Residents are facing conflicts in supporting heritage tourism development by considering current personal interests or long-term community welfare. By applying social dilemma theory, this research illustrates how residents’ social emotions and dilemmas evaluations would affect their supports toward sustainable heritage tourism development. Applying a quota sampling method, a survey of 500 respondents will be conducted in Wulingyuan World Heritage Site in China. The research will establish a theoretical model by structural equation modeling (SEM) to reflect the relationships between residents’ social emotion, efficacy beliefs, temporal concerns and support. Implications for encouraging residents’ cooperation and eliminating tourism conflicts would be raised from the findings.
