Drawn to the unique natural and geographical advantages of ecotourism scenic areas, tourists can roam the natural environment and, at the same time, promote the sustainable development of the scenic area’s ecology. As a result, ecotourism has gradually become a popular type of tourism. Tourists’ perceived authenticity, perceived values, revisit intentions, and environmentally responsible behaviors, which are important variables in understanding their cognition and behaviors, have received extensive attention from scholars. However, few studies have combined tourists’ perceived authenticity, perceived values, revisit intentions, and environmentally responsible behaviors in the context of ecotourism. Taking Huangshan World Natural and Cultural Heritage Site in Anhui, China, as a case study, this study explored the relationship between the perceived authenticity and perceived values of ecotourists, and the respective relationships of perceived authenticity and perceived values with revisit intentions and environmentally responsible behaviors. A survey research method was employed, and the structural equation modeling technique was used to determine the relationships among variables. The results indicated that the perceived authenticity of ecotourists had a significant positive impact on their perceived values. Tourists’ perceived authenticity and perceived values significantly and positively affected their revisit intentions and environmentally responsible behaviors, respectively, while their perceived values played a mediating role in the impact of perceived authenticity on revisit intentions and environmentally responsible behaviors. Theoretically, this study introduces the concept of perceived authenticity into ecotourism, expands the research scope of perceived values, and fills the gaps in the research regarding the impact of perceived authenticity on environmentally responsible behaviors. Practically, it will assist tourism managers in developing a strategic plan for protecting the unique natural resources and cultural customs of scenic spots, producing a valuable interactive experience, and enhancing the collaborative decision-making process, which will lead to the sustainable development of ecotourism destinations.

Safeguarding water resources in tourism contributes to the achievement of the United Nations Sustainable Development Goals (SDGs) and to the wider 2030 Agenda for Sustainable Development. However, sustainable management of water, in order to address both current and future demand for water resources in an equitable and environmentally sound manner, is one of the most significant challenges faced by tourist destinations. Using a case study approach, this research conducts a social network analysis (SNA) of the water policymaking system of Singapore’s hotel industry by longitudinally examining the structure of relations among policy themes and policy stakeholders. The network approach attempts to examine the structural evolution in the water demand management (WDM) policy network based on an analysis of 329 (co)produced policy documents (2001–2020) available in the public domain. A broad range of policy themes, together with divergent policy stakeholders, are uncovered in this interconnected dynamic policy system. Subsequently, systematic policy research is extended to discuss the interrelationships of policy stakeholders and policy themes over the past 20 years. Our findings highlight the network structure of the policy domain and suggest an openness and vibrancy of sustainable WDM as an interdisciplinary policy domain. Cross-sectoral stakeholder engagement has contributed to the evolution and complexity of the policy theme network. The study’s findings provide significant insights into the relationships of policy actors and the evolving network structure of a multidimensional policy framework.
