Highlights
The results of this study confirm that tourists’ perception of external stimuli affects their pro-environmental behavioral responses through the assessment of their environmental cognition. This expands the application of the Stimulus-Organism-Response theory in empirical research on tourism.
The study reveals a positive relationship between media use and tourists’ perception of environmental pollution threats, environmental knowledge, and environmental concern in empirical research on tourism.
Pro-environmental contextual forces play a mediating role, showing that tourists with a strong perception of contextual forces related to the destination are more likely to display favorable pro-environmental behaviors.
Place attachment successfully strengthens the relationship between environmental concern and pro-environmental contextual forces. It also successfully reinforces the relationship between pro-environmental contextual forces and pro-environmental behavior.
Introduction
The global ecological crisis is intensifying, with issues such as pollution, global warming, and natural disasters causing severe disruptions to ecological balance (Yu et al., 2019). Multinational environmental organizations warn that human-driven economic growth has accelerated environmental degradation, while the post-pandemic surge in tourism has further exacerbated greenhouse gas emissions, threatening global environmental sustainability (Gössling & Schumacher, 2010; Holmgren et al., 2019; Schanes et al., 2018). The United Nations World Tourism Organization (UNWTO) predicts that by 2050, the growth of tourism will result in significant increases in energy and water consumption, as well as a dramatic rise in greenhouse gas emissions and waste production (UN_Environment_Programme, 2015). Tourist behaviors, such as excessive resource use and waste generation, are key contributors to environmental degradation (Gao et al., 2021). Media, as a critical channel for information dissemination, has the potential to influence tourists’ pro-environmental behavior by enhancing their environmental knowledge, threat perception, and environmental concern (Keshavarz & Karami, 2016; Y. Liu & Li, 2021; Y. Wu et al., 2018). For example, Gao et al. (2023) proposed a rational-affective-moral factor model, emphasizing the significant role of emotional factors in shaping tourists’ pro-environmental behavior. Z. Xu et al. (2023) examined how destination psychological ownership influences pro-environmental behavior through attributions of responsibility and perceived effectiveness. J. Li et al. (2023) highlighted that enhancing destination attractiveness and place attachment effectively encourages environmentally responsible behavior. Meanwhile, Cheng and Chen (2022) explored the impact of cultural experiences on tourists’ pro-environmental behavior in heritage tourism, identifying cultural attachment as a mediating factor. Hui et al. (2023), based on Media Richness Theory, emphasized the potential of immersive journalism and metaverse promotions in fostering ecological literacy and environmental awareness. However, research on the mechanisms through which media influences tourists’ pro-environmental behavior remains limited, especially in the context of Chinese tourism. Further investigation into the role of media use in promoting pro-environmental behavior is urgently needed to address global environmental challenges and advance sustainable tourism development.
As the environmental impact of the tourism industry intensifies, promoting tourists’ pro-environmental behavior has become a key strategy for mitigating the negative effects of tourism (Becken, 2007). Existing research highlights the significant influence of emotional factors, place attachment, and psychological ownership on tourists’ pro-environmental behavior (Gao et al., 2023; J. Li et al., 2023; Z. Xu et al., 2023). For instance, emotional connections can effectively inspire tourists’ commitment to environmental protection, while psychological ownership can drive behavioral changes through attributions of responsibility and perceived effectiveness (J. Li et al., 2023; Z. Xu et al., 2023). Additionally, immersive media technologies, such as the metaverse and immersive journalism, have been shown to enhance environmental awareness, presenting new possibilities for promoting regenerative tourism (Hui et al., 2023). However, existing literature predominantly focuses on individual-level psychological variables (e.g., self-efficacy, attitudes, and values) or demographic characteristics (Casaló et al., 2019; Schmitt et al., 2018), with relatively limited attention paid to destination-level external factors, such as local community environmental awareness, infrastructure development, and conservation efforts (J. S. Wu, Font, & Liu, 2021). Furthermore, the mechanisms through which place attachment and emotional factors influence pro-environmental behavior remain insufficiently explored (Lewicka, 2011; Qu et al., 2019). Against this backdrop, in-depth exploration of destination-level influencing factors and the role of emotional factors is essential for comprehensively understanding the mechanisms underlying pro-environmental behavior. Such research also provides crucial empirical support and strategic recommendations for enhancing the sustainable development of the tourism industry.
This study, based on the Stimulus-Organism-Response (SOR) theory, aims to construct a comprehensive model to explore the mechanisms through which media use influences pro-environmental contextual forces and pro-environmental behavior via environmental cognitive appraisal, encompassing perceived environmental pollution threats, environmental knowledge, and environmental concern. Specifically, it analyzes the impact of media use on cognitive appraisal factors, uncovers the pathways through which these factors indirectly affect pro-environmental behavior via pro-environmental contextual forces, and clarifies the bridging role of contextual forces between external stimuli and behavioral responses. This study seeks to deepen the understanding of the mechanisms underlying the formation of pro-environmental behavior while providing empirical support for governments and tourism managers to optimize environmental information dissemination strategies and promote sustainable tourism development.
This study theoretically innovates by integrating media use with the multidimensional elements of environmental cognitive appraisal, clarifying the roles of perceived environmental pollution threats, environmental knowledge, and environmental concern as mediating variables. This not only enriches the application of the SOR theory in the field of pro-environmental behavior but also highlights the critical role of cognitive appraisal in shaping individual pro-environmental behavior. By introducing the variable of pro-environmental contextual forces, the study further extends the explanatory power of the SOR theory in elucidating how external stimuli influence behavioral responses through internal cognitive appraisal. This addition deepens the theoretical chain linking external stimuli, cognitive appraisal, and behavioral responses, offering a new perspective in the field of pro-environmental behavior.
This study constructs a comprehensive model based on the SOR theory to systematically explore the relationships among media use, environmental cognitive appraisal, pro-environmental contextual forces, and pro-environmental behavior. It begins by outlining the research background and theoretical foundation, followed by the development of research hypotheses through a review of the literature. A questionnaire is then developed as a measurement tool, and an empirical study is conducted to test the model’s hypotheses. Finally, theoretical implications and practical recommendations are proposed based on the research findings. This study provides a novel theoretical framework and practical pathways for researchers and practitioners in the fields of environmental protection and sustainable tourism.
Literature Review and Research Hypothesis
SOR Paradigm
The SOR model by Mehrabian and Russell explains how external cues shape behavior. SOR clarifies how stimuli affect internal states, influencing behavior (Mehrabian & Russell, 1974). This model studies environment’s impact on behavior (Sun et al., 2021). In SOR, Stimulus (S) affects the organism (O), the psychological response to stimuli. Response (R) is the behavioral reaction to stimulus content. SOR theory is used across research areas. For instance, Song et al. (2022) linked it to low-carbon behavior, using climate policy awareness as stimulus and environmental emotions as experiences. They assessed its influence on eco-friendly travel. Also, Fakfare and Sangpikul (2022) used SOR to analyze COVID-19 policies’ effects on Thai tourism. They studied local satisfaction, fear, and avoidance behaviors. This enriches insights into tourism policy amid the pandemic.
The SOR theory has been widely applied across various research fields, revealing how external stimuli influence behavior through the organism’s psychological state. For example, Song et al. (2022) linked the theory to low-carbon behavior, treating climate policy awareness as the stimulus, environmental emotions as the organism, and assessing their impact on environmentally friendly travel. Fakfare and Sangpikul (2022) applied the SOR model to analyze the impact of COVID-19 policies on Thailand’s tourism industry, examining local residents’ satisfaction, fear, and avoidance behavior, thereby offering new insights into tourism policy research during the pandemic. In addition, Nonthapot et al. (2024) analyzed water tourism demand in the Mekong River Basin using the SOR theory, uncovering how water transportation services, as the stimulus, influenced tourists’ revisit intentions. Hamdan and Basrowi (2024) explored the mediating role of community entrepreneurship development in the impact of geographical conditions, local wisdom, and traditional culture on the sustainability of tourism villages, highlighting community factors as the organism driving positive contributions to tourism village sustainability. Moreover, Florido-Benítez (2024) examined the impact of smart tourism destination development in Spain on tourist behavior, emphasizing how technology and digital services, as stimuli, enhance tourist experiences and satisfaction. Xuan et al. (2024) utilized the SOR model to explore the influence of social networks as stimuli on green hotel choices in sports activities in Vietnam, demonstrating the formation process of trust and intention in green consumption behavior. These studies illustrate the broad applicability of the SOR theory across diverse fields, from policy impacts to tourism behavior, showcasing its versatility in addressing complex behavioral dynamics.
The Environmental Cognitive Appraisal Theory’s “primary-secondary-reappraisal” process (Lazarus et al., 1970) is pivotal. It links primary appraisal to pollution threats, secondary appraisal to knowledge, and reappraisal to concern. Thus, this study, using SOR, probes media’s impact on pro-environmental actions. Here, stimulus is media’s effect, organism is cognitive processing (threat perception, knowledge, concern), and response is pro-environmental behaviors (Figure 1).

Conceptual model.
Media Use
Media use involves exposure and attention. Exposure is info intake, while attention is focused info processing. Media conveys ideologies and values through universal symbols, evoking resonance (Potter, 2014). It simplifies complex climate science, aiding understanding and emotional formation. Media types studied are traditional (television, newspapers) and social (internet, networks). Traditional media boosts climate awareness (Holbert et al., 2003). Internet spurs climate info search (Zhao, 2009). Social media elevates eco knowledge (Karahan & Roehrig, 2015). Media, per agenda-setting theory, shapes knowledge, attitudes, and priorities, guiding perceptions on issues.
Perceived Environmental Pollution Threats
Perceived environmental threats are gauged threat levels from degradation (Arthur & Quester, 2004). O’Connor et al. (1999) link it to recognizing causes of environmental harm. Franzen and Meyer (2010) note rational insight, action willingness, and emotional impact. This study views it as rational insight into pollution causes and understanding.
Rogers (1975) introduced Protective Motivation Theory (PMT) for understanding how threats drive environmental behavior. It asserts that perceiving harm and identifying threats prompt protective actions (Carrete et al., 2018). As environmental issues impact personal interests, individuals adjust their stance for survival, engaging in eco-friendly acts (Z. Zhang et al., 2018). People act to shield against environmental risks, safeguarding their lives (Ding et al., 2018). When public sees harm from degradation, they’re likelier to join green efforts (Dong et al., 2018).
Media shapes understanding of environmental topics like greenhouse effect, climate change, and pollution. It underscores Earth, human, and animal threats, effectively gauging issue impact. With wider media reach, influence strengthens. As media use rises, perception of pollution threats grows. Thus, we posit (
Environmental Knowledge
Environmental knowledge encompasses understanding about conditions, climate change, perspectives, and ecological effects of consumption/production (Pagiaslis & Krontalis, 2014). It also involves grasping issues and solutions (Angreani et al., 2022). Research suggests higher per capita income relates to greater environmental knowledge, linked to wealth growth (Guerra et al., 2016). Knowledge influences conservation intent, predicting intentions and behaviors (Gkargkavouzi et al., 2019). Otto and Pensini (2017) agree on knowledge’s role in behavior change. Thus, this study views environmental knowledge as awareness and understanding of various aspects.
Traditional media raises awareness. Zhao (2009) highlighted media’s role in understanding global warming. Social media aids awareness too. Internet boosts ecological knowledge (P. Liu et al., 2021). Y. Liu and Li (2021) linked both media types to environmental understanding. This study proposes
Environmental Concern
Environmental concern is individual focus on environmental matters. Vainio and Paloniemi (2014) added overall environmental value and future worries. Stern et al. (1995) identified egoistic, altruistic, and biospheric concern dimensions. Schultz (2001) tied self-nature link to impact perception. These dimensions merge into environmental concern—individual attention, various ecological perspectives.
Media exposure, including mass media and social media, strongly shapes environmental awareness and concern. Mass media’s consistent, credible info boosts awareness (Hansen, 2013). Social media’s interactive role aids communication, fostering engagement (Newman & Dale, 2007). Public involvement observes environmental shifts. Social media encourages responsibility (Y. Wu et al., 2018). Media’s environmental coverage elevates public concern. Thus, this study suggests the following hypothesis:
Pro-Environmental Contextual Forces
Pro-environmental contextual forces refer to external conditions or factors that support individuals in engaging in pro-environmental behavior. According to Guagnano et al. (1995) and Stern and Oskamp (1987), these external forces include material factors (such as the availability of environmental facilities and resources), laws and policies (such as environmental regulations and incentives), social factors (such as group norms and social support), economic conditions (such as costs and subsidies), cultural contexts (such as the prevalence of pro-environmental values), and technological support (such as the application of green technologies). These factors shape individuals’ behavioral decision-making environments, providing motivation for environmental protection. Furthermore, Stern et al. (1999) emphasized that pro-environmental contextual forces encompass not only macro-level structural factors (such as laws and policies) but also micro-level individual experiences (such as destination facilities and landscapes). Qin and Hsu (2022) introduced this concept into the study of tourist behavior, arguing that pro-environmental contextual forces significantly influence tourists’ pro-environmental behavioral tendencies at destinations.
In this study, pro-environmental contextual forces specifically refer to external factors that influence tourists’ pro-environmental actions at destinations. These include destination facility conditions, such as the availability of waste recycling facilities and green transportation; policy support, such as environmental initiatives and promotional activities by local governments; social norms, such as the environmental awareness and behavior of local residents and tourists; and community involvement, such as the level of support and willingness to cooperate with environmental protection efforts by the local community. Therefore, studying pro-environmental contextual forces helps to uncover the deeper impact of external environments on individual pro-environmental behavior.
PMT elucidates environmental threat perception and response. It explores how threats attract and impact behavior. PMT assesses threat appraisal through perceived vulnerability and severity (Keshavarz & Karami, 2016). Higher threat exposure likelihood and severe consequences yield stronger protective responses, heightening environmental awareness. Hence, stronger pollution threat perception boosts sensitivity to external contextual forces.
Environmental knowledge shapes lifestyles via personal info exposure (Hobson, 2003). Brunswicker and Chesbrough (2018) linked knowledge to eco-friendly actions in the hotel industry. Adequate knowledge is vital for perceiving pro-environmental contextual forces. Environmental concern fosters cooperation, awareness, and involvement (Borg et al., 2020). Yet, higher concern doesn't always mean more sacrifices (Nordlund & Garvill, 2002), but it increases eco-friendly actions. Consequently, heightened environmental concern aligns with stronger perception of pro-environmental contextual forces.
To conclude, this study posits that in tourism, perception of pollution threats, environmental knowledge, and concern impact pro-environmental contextual forces. The following hypotheses are proposed:
Pro-Environmental Behavior
Pro-environmental behavior encompasses green, responsible, and impactful actions (Han, 2015). Ho, Liao, and Rosenthal (2015) expand it to behaviors minimizing harm or maximizing benefits. Research defines diverse types like general and place-specific (Halpenny, 2010), individual, collective, and policy-supportive (Walker et al., 2015). In this study, pro-environmental behavior signifies individual eco-friendly actions in specific tourism contexts.
In recent years, research on Pro-environmental behavior has continued to expand, delving into its research hotspots, theoretical frameworks, and behavioral driving factors. Carvajal-Trujillo et al. (2024) conducted a bibliometric analysis to review the development trends in tourist pro-environmental behavior research from 1999 to 2023, revealing the evolution of research hotspots and future research directions. Jaffar and Latiff (2024) provided a systematic review based on the Norm Activation Model (2018–2023), emphasizing the key role of responsibility and normative awareness in promoting protective behavior, offering theoretical support for practice. Brick et al. (2024) investigated research practices in environmental psychology, analyzing current methodological trends in pro-environmental behavior research, and pointed out the need to strengthen cross-cultural studies and the integration of multidisciplinary approaches. Mi et al. (2024) used knowledge mapping analysis to reveal research hotspots and frontiers in the field of pro-environmental behavior, especially advancements in public perception, behavioral drivers, and policy impacts. Y. Zhang et al. (2024) studied the determinants of pro-environmental behavior among higher education students, highlighting the importance of education in shaping environmental attitudes and behaviors, providing practical insights for future sustainable development. Together, these studies provide a theoretical foundation for a deeper understanding of the complexity of pro-environmental behavior and offer strong support for the design of policies and educational practices. The influencing factors of pro-environmental behavior are shown in Table 1.
Factors Influencing Pro-environmental Behavior.
The broken windows theory clarifies pro-environmental contextual forces’ impact on behavior. It asserts that disorderly environments foster disorderly behavior acceptance (Kelling & Wilson, 1982). Addressing minor issues averts more severe problems (Stitt, 2023). Similarly, well-maintained settings encourage positive behavior (Lang et al., 2010). J. S. Wu et al.’s (2021) findings affirm that appealing ecological park environments boost responsible intentions. The theory links macro-environment and behavior, backing contextual forces’ role in behavior determination.
Previous research by Lee (2011) highlighted how exposure to environmental info boosts values and protective behavior among students in Hong Kong. Steg and Vlek (2009) added that lacking transportation options affects behavior. Hence, pro-environmental contextual forces can directly shape tourist behavior. Higher forces lead to greater pro-environmental actions. Consequently, this study suggests that pro-environmental contextual forces impact tourist behavior positively, forming the following hypothesis:
Multiple Mediation Effects
This study delves into how media use influences pro-environmental contextual forces through multiple mediating roles of environmental pollution threat perception, knowledge, and concern. Media is crucial in enhancing perceptions, knowledge, and concern about environmental issues (Dong et al., 2018; Z. Li, 2021). Environmental info leads to lifestyle changes and promotes pro-environmental forces. Hence, media influences multiple pathways, involving threat perception, knowledge, concern, and contextual forces.
Drawing from the above research, media use positively affects threat perception, knowledge, and concern. Likewise, these factors enhance pro-environmental contextual forces. Thus, heightened media engagement links to stronger pollution threat perception, increased knowledge, and heightened concern. Consequently, these factors collectively amplify pro-environmental contextual forces. This study posits the following research hypotheses:
Place Attachment
Place attachment evolves from cognitive (place dependence) and affective (place identity) bonds (Patwardhan et al., 2020). Functional ties characterize place dependence (Gu & Ryan, 2008), while emotional or symbolic links define place identity (Loureiro, 2014). When a place caters to needs, it fosters attachment. In this study, following Patwardhan et al. (2020), place attachment signifies travelers’ cognitive and affective bonds formed via direct and indirect interactions with a destination.
Tourists’ place attachment is closely related to their concern for the natural environment of a specific destination. According to Social Identity Theory (SIT), individuals who identify with a group are more likely to act in ways that benefit the group (Brown, 2000). Similarly, individuals who are attached to a place and identify with its community are more likely to prioritize the interests of the place over their own self-interest (Carrus et al., 2014; Scannell & Gifford, 2014). Specifically, people with emotional ties to a place may care more about shaping its pro-environmental contextual forces through their perceived environmental pollution threats, environmental knowledge, and environmental concern. Consequently, individuals with stronger place attachment are likely to strengthen the effects of perceived environmental pollution threats, environmental knowledge, and environmental concern on pro-environmental contextual forces. Conversely, individuals with weaker place attachment may diminish these effects. Therefore, in the context of tourism, place attachment moderates the relationships between perceived environmental pollution threats, environmental knowledge, environmental concern, and pro-environmental contextual forces. Based on this, the following hypotheses are proposed:
For the relationship between place attachment, pro-environmental contextual forces, and pro-environmental behavior, the perspective of place attachment theory supports the notion that place attachment strengthens the positive link between pro-environmental contextual forces and pro-environmental behavior. Attachment to a place can evoke a sense of responsibility for the local environment, thereby encouraging activities that contribute to environmental sustainability. Tourists with emotional attachment to a specific destination may develop an extended sense of empathy toward the destination, making them more willing to engage in behaviors that benefit it (Gosling & Williams, 2010; Kim & Thapa, 2018). Kim and Koo (2020) also found that anticipated positive emotions and empathetic concern influence pro-environmental behavior, moderated by the degree of place attachment. Based on these findings, individuals with stronger place attachment are more likely to have their pro-environmental contextual forces effectively promote pro-environmental behavior. Conversely, for individuals with weaker place attachment, the influence of pro-environmental contextual forces on pro-environmental behavior may be diminished. Thus, for tourists visiting specific destinations, place attachment can moderate the relationship between pro-environmental contextual forces and pro-environmental behavior. Based on this, the following hypothesis is proposed:
This study investigates how media use impacts pro-environmental behavior within tourism. Media use is the independent variable, while environmental pollution perception, environmental knowledge, environmental concern, and place-based pro-environmental attitudes act as mediators. Pro-environmental behavior is the dependent variable, moderated by place attachment. Figure 2 depicts the research model, shaped through a comprehensive literature review.

Methodology
Sample
This study focuses on exploring pro-environmental behavior in the tourism context. Data were collected through an online questionnaire survey conducted from May 1 to June 1, 2023. A total of 400 questionnaires were collected, with 355 valid responses retained after excluding invalid ones. The questionnaire was distributed via social media, tourism communities, and travel agency email lists to reach target groups from diverse backgrounds and ensure sample diversity. Participants were required to meet the criteria of being 18 years or older and having participated in at least one tourism activity within the past year. To ensure data validity, measures such as restricting IP submissions, removing low-quality responses, and checking logical consistency were implemented. Although the study is limited by the internet accessibility and language constraints inherent to online surveys, the use of multiple distribution channels and a rigorous data cleaning process maximized sample randomness and data quality.
Measures
The research questionnaire comprises participants’ background information and subjective perceptions of research variables. The first section collects gender, age, education, income, and residence data. The second part gauges seven latent variables via a 7-point Likert scale (1–7), adapted from previous studies.
The media usage items adopted from Huang (2016) include the ways in which environmental information is accessed, the frequency of news exposure, the level of attention given, and the assessment of how relevant the information is to the destination. These items encompass different media types, such as television, radio, newspapers, magazines, the internet, and social media platforms. Environmental threat perception employs six items from P. Liu et al. (2021) about issues’ severity like water, air, noise pollution, waste, and insufficient green spaces.
Environmental knowledge utilizes four items from Zebardast and Radaei (2022) regarding information on causes, consequences, prevention, and improved quality of life related to environmental crises. Environmental concern’s egoism, altruism, and biospheric dimensions (Stern et al., 1995) are measured through two items each.
Pro-environmental contextual forces employ seven items modified from Qun and Hsu’s (2022) dimensions, assessing factors like environment, quality, facility readiness, policy effectiveness, and travel companions. Pro-environmental behavior uses one item from Qun and Cathy and three from Kim and Koo (2020), focusing on policies, environmental quality, local flora and fauna protection, and future eco-friendly actions.
Place attachment is assessed through five items, two from J. Xu and Han (2019) and three from J. Zhang and Wang (2022), encompassing emotional connection, willingness to stay, local residents’ approval, and affinity for natural features.
The scale items developed in this study and the data sources are shown in Table 2.

Data Analysis
The data analysis of this study will begin with descriptive statistics to examine the distribution of sample characteristics using SPSS 25.0 statistical software. Subsequently, the analysis and estimation procedure in Smart PLS 3.2.8 will be employed to test the structural equation model and examine the significance of research hypotheses. First, the reliability and validity of the scales will be assessed, followed by testing the goodness-of-fit between the research model and the sample size. Finally, path analysis, mediation effect analysis, and moderation effect analysis will be conducted to test the research hypotheses.
Study Results
Descriptive Statistics
The sample distribution in this study covers several key variables, including gender, age, education level, income, and residential area, demonstrating high representativeness (as shown in Table 3). Specifically, the gender ratio is relatively balanced, with 50.7% male and 49.3% female participants. The age range is broad, with the majority falling in the 51 to 60 age group, while other age groups are also represented. Educational levels range from high school to postgraduate, with bachelor’s degree holders making up the largest proportion (33.0%), aligning with the general educational characteristics of the tourism population. Income distribution varies from below 5,000 RMB to above 10,000 RMB, reflecting the participation characteristics of different income groups. In terms of residential areas, the sample includes participants from county-level and below areas, cities, and other types of regions, adequately representing the behavioral characteristics of tourists from diverse geographical backgrounds. Therefore, the sample in this study exhibits good diversity and representativeness, providing a reliable foundation for the research conclusions.

Measurement Model Validation
Convergent Validity
This study examined the reliability of the items using factor loading. The criterion for testing was based on the suggestion by Hair et al. (2019), which states that the correlation between the formatively measured construct and the single-item construct, measuring the same concept, should be 0.70 or higher. As shown in Table 4, the factor loadings of each construct in this study ranged from 0.816 to 0.888, all exceeding 0.7.
Reliability of Items.
Fornell and Larcker (1981) and Nunnally (1978) pointed out that Cronbach’s α should be greater than .7, composite reliability should be greater than .7, and average variance extracted should be greater than 0.5. In this study, the Cronbach’s α values for all constructs ranged from .837 to .932, indicating that all values are greater than .7. The composite reliability ranged from .902 to .946, indicating that all values are greater than .7. The average variance extracted ranged from 0.699 to 0.754, indicating that all values are greater than 0.5. Based on these statistical data, the study demonstrates good convergent validity (Table 5).
Convergent Validity Analysis.
Discriminant Validity
This study used the average variance extracted (AVE) method to assess discriminant validity. Fornell and Larcker (1981) suggest that the square root of AVE for each construct should be greater than the correlation coefficients between the pairs of variables, indicating discriminant validity among the constructs. In this study, most of the AVE values were greater than the squared correlation coefficients, indicating that the results have discriminant validity (Table 6).

Conclusion and Discussion
This study primarily investigates the influence of media use on pro-environmental responses in the context of tourism. By integrating factors such as “media use” and employing mediating variables including “perceived environmental pollution threats,”“environmental knowledge,” and “environmental concern,” the study examines their impact on “pro-environmental contextual forces” and subsequently on “pro-environmental behavior.” A research framework and corresponding hypotheses were proposed, and data were collected through a questionnaire survey. The proposed model and hypotheses were tested using structural equation modeling to validate the findings.
Academic Contribution
Impact of Media Use on Perceived Environmental Threats, Environmental Knowledge, and Environmental Concern
This study examines the relationships between media usage and environmental threat perception, environmental knowledge, and environmental concern. The findings indicate that media usage positively influences these factors. Consistent with previous literature, the results confirm that media usage significantly enhances environmental knowledge, particularly in explaining environmental issues and their solutions. Hansen (2013) and Newman and Dale (2007) point out that traditional and social media effectively increase public environmental concern by providing consistent and credible environmental information and fostering interactive participation, especially by emphasizing the relationship between humans and nature and a sense of responsibility (Y. Wu et al., 2018). Similarly, Zhao (2009) and P. Liu et al. (2021) highlight the significant role of media, especially online media, in disseminating environmental knowledge, such as promoting scientific understanding of climate change and pollution. Moreover, the interactivity of social media enhances the efficiency of knowledge dissemination (Y. Liu & Li, 2021). Rogers (1975) and Dong et al. (2018) also note that media amplifies public perception of environmental threats, such as climate change, pollution, and ecological degradation, particularly in raising awareness of the personal impact of pollution (Ding et al., 2018). These findings suggest that modern society’s high dependence on media has led to greater attention to its coverage of environmental and public issues. Scholars believe that media provides a virtual window for people to access previously unseen natural environments, fostering environmental awareness, and promoting conservation behavior.
A comparison of the effects on Environmental Concern (EC), Environmental Knowledge (EK), and Perceived Environmental Pollution Threats (EP) reveals that the impact on Environmental Concern is the strongest, indicating that media is most effective in enhancing public emotional engagement and sense of responsibility toward environmental issues. The effect on environmental knowledge is the second strongest, suggesting that media plays a significant role in disseminating environmental knowledge, though its impact is less pronounced than on environmental concern. The effect on perceived environmental pollution threats is the weakest, indicating that media is relatively less effective in strengthening individual awareness of specific pollution threats. This implies that while media has substantial potential to enhance public emotions and knowledge, its role in promoting awareness of specific threats may require supplementary interventions, such as field education or direct experiences.
The Influence of Perceived Environmental Pollution Threats, Environmental Knowledge, and Environmental Concern on Pro-Environmental Contextual Forces
The results of this study confirm that environmental knowledge, pollution threat perception, and environmental concern all have a significant positive impact on pro-environmental contextual forces. Among them, environmental knowledge exerts the greatest influence, indicating that an individual’s mastery of environmental knowledge significantly enhances their perception of external environmental support. Pollution threat perception ranks second, showing that the sensitivity to external contextual factors is influenced to some extent by perceived threats. Environmental concern has the least influence, suggesting that individuals’ emotions and values have a relatively weaker impact on contextual factors.
Environmental knowledge directly influences individuals’ understanding of environmental issues, helping them recognize and perceive external support factors such as policies or infrastructure. Hobson (2003) and Brunswicker and Chesbrough (2018) emphasized the importance of knowledge in promoting pro-environmental behavior, consistent with the study’s findings, which highlight that adequate information increases sensitivity to contextual support. While previous literature often focuses on the application of knowledge in specific actions, this study emphasizes its impact on external contextual support factors.
The strength of individuals’ perceptions of pollution threats directly affects their demand for and sensitivity to external support factors. According to Protection Motivation Theory (PMT; Keshavarz & Karami, 2016), the higher the perceived threat intensity, the more likely protective behavior will be triggered. However, as a highly situational factor, the influence of threat perception may be less stable than that of knowledge. Keshavarz and Karami (2016) and Dong et al. (2018) confirmed the significant impact of threat perception on protective behaviors, and this study similarly demonstrates its significant effect on pro-environmental contextual forces. However, prior research has predominantly focused on the direct relationship between threat perception and individual behavior.
Environmental concern represents individuals’ attitudes and value orientations, with a more indirect influence that is often reflected in behavior choices emphasizing environmental importance. Nordlund and Garvill (2002) noted that high environmental concern does not necessarily translate into action, especially when such actions involve high costs or sacrifices, which may explain its weaker influence. Borg et al. (2020) suggested that environmental concern can promote cooperation and participation, a relationship that this study also confirms. However, previous literature also points out that high concern does not necessarily lead to more action (Nordlund & Garvill, 2002), explaining the relatively low impact of environmental concern observed in this study.
This study broadly defines contextual support as encompassing legal, social, and technological dimensions, which may have increased the pivotal role of knowledge in relation to these factors, whereas prior literature tends to focus more on the correlation with single-dimensional factors. By expanding the research to include sensitivity to external contextual factors, this study contributes to the field by addressing an area less emphasized in existing literature.
Impact of Pro-Environmental Contextual Forces on Pro-Environmental Behavior
This study demonstrates a direct positive influence of pro-environmental contextual forces on pro-environmental behavior, in line with the conceptual framework of the broken windows theory. This highlights the active role that pro-environmental contextual forces play in driving pro-environmental behavior at tourist destinations.
The findings of this study align with the Broken Windows Theory (Kelling & Wilson, 1982), which suggests that clean and orderly environments promote positive behaviors, while chaotic environments inhibit them. Well-maintained pro-environmental contextual factors, such as clean tourist facilities and effective environmental policies, reduce both psychological and practical barriers for tourists to engage in pro-environmental actions, thereby encouraging positive behaviors. This study focuses on behaviors in specific tourism contexts, making the direct impact of contextual forces on behavior more evident. The Broken Windows Theory emphasizes that good environmental conditions facilitate positive behaviors, and the results of this study confirm the significant influence of contextual factors on pro-environmental behaviors (Lang et al., 2010; J. S. Wu et al., 2021). For instance, Wu et al. found that attractive ecological park environments enhance tourists’ intentions to act responsibly. However, while the Broken Windows Theory is typically applied to the prevention of destructive behaviors, this study extends its application to positive behaviors, particularly in promoting pro-environmental actions within tourism contexts.
Similar to previous research findings, such as Lee’s study, which demonstrated that exposure to environmental information can enhance values and protective behaviors, this study also found that contextual forces (e.g., environmental education or promotion) can directly influence behavior. Steg and Vlek (2009) proposed that the lack of alternative transportation options and other contextual constraints can inhibit pro-environmental behaviors. This study supports the view that contextual forces are critical determinants of behavioral decision-making. The results of this study are consistent with the literature, all of which confirm the significant role of contextual forces in promoting pro-environmental behavior and support the environmental-behavior linkage proposed by the Broken Windows Theory. While the literature often defines contextual forces narrowly (e.g., transportation or education), this study incorporates multi-dimensional contextual forces (e.g., social, policy, and infrastructure factors), making their influence more pronounced.
Mediating Effects of Environmental Threat Perception, Environmental Knowledge, and Environmental Concern on Media Use and Pro-Environmental Contextual Forces
This study explores how media use (MU) influences pro-environmental contextual forces (PC) through three mediating variables: perceived environmental pollution threats (EP), environmental knowledge (EK), and environmental concern (EC). Among these, environmental knowledge (EK) has the most significant mediating effect, followed by environmental concern (EC), with perceived environmental pollution threats (EP) having the least impact.
The findings of this study align with previous literature (Zhao, 2009; Z. Li, 2021), which highlights that media serves as an important channel for disseminating environmental knowledge, particularly in enhancing understanding of environmental infrastructure and policies. The literature (Hansen, 2013; Y. Wu et al., 2018) suggests that the emotional appeals and consistent information provided by the media can enhance individuals’ environmental concern, which is consistent with the results of this study. Additionally, the literature (Dong et al., 2018) emphasizes that media can increase awareness of environmental threats, such as the consequences of pollution and climate change, a viewpoint supported by this study’s findings.
The Influence of Place Attachment on Environmental Threat Perception, Environmental Knowledge, Environmental Concern, and Pro-Environmental Behavior
This study found that place attachment did not show a significant moderating effect on the relationship between perceived environmental pollution threats and environmental knowledge with pro-environmental behavior. However, place attachment exhibited a significant negative moderating effect on the relationships between environmental concern and pro-environmental behavior, as well as pro-environmental contextual forces and pro-environmental behavior. This indicates that while place attachment can play a positive role in certain contexts, it may also weaken the influence of other environmental factors on pro-environmental behavior under specific conditions. Regarding the moderating effect of place attachment on perceived pollution threats and environmental knowledge, Scannell and Gifford (2014) suggest that place attachment should enhance individuals’ sensitivity to pollution perception and knowledge, thereby promoting pro-environmental behavior. However, this study did not observe such a significant effect. This might be because tourists are more focused on personal experiences and short-term benefits, with place attachment having a weaker influence on cognitive factors. Secondly, in the moderating effect of place attachment on environmental concern, Carrus et al. (2014) argued that place attachment could prioritize environment-related concerns specific to the place, thereby encouraging pro-environmental behavior. However, this study revealed a negative moderating effect in this relationship. This could be because individuals with high place attachment tend to focus more on specific local interests, neglecting broader environmental protection goals. Lastly, for the moderating effect of place attachment on contextual forces, Kim and Koo (2020) found that place attachment could amplify the positive impact of pro-environmental contextual forces on pro-environmental behavior. Nevertheless, this study discovered that in tourism contexts, individuals with high place attachment might prioritize direct local benefits, thereby weakening the overall influence of contextual factors. This may reflect that tourists with high place attachment are less sensitive to other environmental factors.
In the context of tourism, place attachment tends to be short-term and specific. Tourists are more inclined to focus on local interests directly related to their travel experience, which may diminish their attention to broader environmental issues. Functional attachment (such as whether a place meets their needs) may take precedence over emotional attachment (such as a sense of place identity), leading to the complex effects of place attachment on pro-environmental behavior. While some literature emphasizes place attachment in everyday contexts, this study focuses on the tourism context, highlighting the uniqueness of place attachment in tourist behavior and its potential differences in manifestation.
Practical Implications
The study’s findings suggest three recommended directions for policy enhancement aimed at promoting tourists’ pro-environmental contextual forces and encouraging pro-environmental behavior through media use:
Local Destination Policies: Local destination policies play a pivotal role in shaping tourists’ pro-environmental behavior. To capitalize on the information-rich environment, local governments can leverage various communication channels to disseminate pro-environmental contextual forces. Through online platforms such as tourism websites, social media, and self-media, destinations can provide diverse and engaging information about their ecological conservation efforts. By showcasing their commitment to environmental preservation, destinations can create a positive image that resonates with potential tourists. Additionally, focusing on enhancing natural landscape features, such as public spaces, air quality, water bodies, and architectural elements, can leave a lasting impression on visitors. Utilizing clear and informative public facilities, such as posters, banners, and images, can guide tourists toward environmentally friendly actions. Implementing eco-friendly alternatives like shared bicycles, public transportation, and shuttle services within the scenic area can further encourage pro-environmental behavior and reduce energy consumption.
Education and Awareness Campaigns: Implementing comprehensive education and awareness campaigns can significantly impact tourists’ pro-environmental behavior. By integrating environmental topics into guided tours, workshops, and interactive experiences, destinations can enhance tourists’ understanding of the local ecosystem and the importance of sustainability. Collaborating with environmental experts and organizations can add credibility to these initiatives. Through such efforts, tourists can develop a deeper connection to the destination and a heightened sense of responsibility toward its preservation.
Media Partnerships and Collaborations: To effectively enhance tourists’ environmental knowledge and concern, media should adopt the following specific strategies: Firstly, increase tourists’ sense of identification through localized content. Media can create special reports or short videos that integrate local ecological features and environmental issues, such as showcasing examples of natural landscape conservation or ecological threats at tourist destinations (e.g., water scarcity or waste management challenges). This makes the content more relatable and easier for tourists to understand and connect with. Secondly, enhance engagement through interactive content. Social media platforms can host online environmental knowledge quizzes, virtual tours of ecological attractions, or interactive games, allowing tourists to learn about environmental protection while being entertained. For example, an “Eco Challenge” short video campaign could encourage tourists to upload and share creative content showcasing their eco-friendly practices. Thirdly, focus on emotional storytelling to evoke resonance. Media can use real-life cases, documentaries, or photo exhibitions to illustrate the impact of environmental degradation on wildlife or local residents, arousing emotional connections and a sense of responsibility for environmental protection. For instance, highlighting success stories of endangered species conservation or showcasing the positive changes brought about by pollution control efforts. Lastly, expand outreach through multi-platform collaboration. Media can partner with travel websites, destination management organizations, or environmental organizations to embed concise and impactful environmental messages into travel guides, brochures, or digital screens in public spaces, ensuring broader coverage among tourists. These strategies not only improve tourists’ environmental knowledge but also enhance their environmental concern through emotional triggers and interactive engagement, thereby laying the foundation for promoting pro-environmental behavior.
By following these recommendations, destinations can leverage media’s influence to nurture pro-environmental contextual forces and behaviors among tourists. This dual-purpose approach supports both natural resource preservation and an enhanced tourist experience, aligning with sustainable and responsible tourism principles.
Destination authorities should prioritize the conservation of local attributes, encompassing wildlife, plant life, cultural treasures, and intangible heritage. Concurrently, local governments or tourism entities should craft high-quality promotional content, such as images and videos showcasing unique species. For instance, China’s national treasure, the giant panda, primarily found in Sichuan Province’s mountains and valleys, underscores the value of preservation. Through compelling visuals and promotional materials, the Chinese government has championed panda protection, making it an emblem of Chengdu. This serves as a reminder that neglecting these special species and cultural heritage risks their extinction. Diverse media channels, featuring impactful reports, can underscore this message effectively. Promoting species and cultural heritage conservation heightens awareness and serves as a promotional tool, driving tourism development.
These strategies emphasize environmental consciousness and the need to address environmental threats. Short-term promotional efforts can effectively reinforce the ecological significance, ensuring a harmonious relationship between tourism and nature.
Local attachment is vital in shaping pro-environmental behavior policies. Tourists’ affinity for a destination can be nurtured through evocative mediums like imagery, narratives, verse, and cinematic scenes, triggering emotional bonds. This emotional tethering to a distant place might not solely arise from visiting but could also sprout from lifelong exposure to cultural heritage. For instance, locales like Helan Mountain, West Lake, Mount Hua, and Yueyang Tower have been immortalized in poetry and tales, infusing them with cultural significance that fosters emotional ties and a sense of local identity.
Tourist destination governments should acknowledge the pivotal role of these cultural assets in cultivating local attachment. Thus, when shaping pro-environmental behavior initiatives, policies should deepen tourists’ sense of local affinity by delving into and celebrating the cultural roots and heritage of the area.
Research Limitations and Future Development
Firstly, this study has certain limitations regarding its sample size, as it focuses solely on Chinese tourists, which limits the generalizability of the findings to some extent. Future research should expand the sample scope to include international tourists or groups with diverse cultural and socio-economic backgrounds, enabling cross-cultural comparisons and enhancing the generalizability and applicability of the results.
Secondly, this study primarily explores the impact of media use on pro-environmental behavior but does not fully consider the role of contextual factors such as cultural values, social norms, and economic conditions on environmental attitudes and behaviors. Since cultural and socio-economic backgrounds significantly influence the formation of pro-environmental behavior, future research should incorporate these contextual factors into the analytical framework to provide a more comprehensive understanding and reveal the complex interactions between media, contextual factors, and individual behavior.
Thirdly, this study primarily employs quantitative research methods, using questionnaire surveys and structural equation modeling for analysis. While these methods ensure rigor and systematicity, they do not delve deeply into the motivations and emotional experiences underlying tourists’ pro-environmental behaviors. Future studies could adopt qualitative research methods, such as in-depth interviews, focus groups, or case studies, to explore in greater detail the intrinsic drivers of tourists’ pro-environmental behavior and their complex relationship with media use.
Fourthly, this study focuses on the overall impact of contextual forces but does not analyze specific dimensions such as economic incentives, social infrastructure, or policy regulations. Future research could further explore these specific dimensions of contextual forces to reveal their precise effects on pro-environmental behavior, thereby providing empirical evidence for more targeted interventions.
Lastly, this study focuses on general pro-environmental behavior without distinguishing between private-sphere behaviors and public-sphere behaviors. Private-sphere behaviors typically involve individual actions, such as reducing personal waste, while public-sphere behaviors involve collective or community-level actions, such as participating in local environmental protection initiatives. Future research could investigate the characteristics and influencing factors of these two types of behaviors in specific contexts.
These limitations point to several directions for future research, including expanding the sample scope to encompass diverse populations, incorporating cultural and socio-economic factors into the analytical framework, combining quantitative and qualitative research methods, exploring specific dimensions of contextual forces, and distinguishing the characteristics of different behavioral domains. Addressing these gaps could further enhance the scientific, generalizable, and practical value of research on media use and pro-environmental behavior.
