Spatial Correlation and Influencing Factors of Tourism Eco-Efficiency in the Urban Agglomeration of the Yangtze River Delta Based on Social Network Analysis

Tourism eco-efficiency analysis is an effective tool to solve the problem of sustainable tourism development. The evaluation index system was constructed in study, and undesirable output super-slacks-based measure model used estimate 26 cities Yangtze River Delta. Then, modified gravity based on values each city construct a spatial correlation network. structural characteristics association networks eco-efficiency, interrelationships among different cities, roles played by blocks were explored using social network analysis. quadratic assignment procedure (QAP) applied analyze influencing factors that affect formation eco-efficiency. results show has overall increasing trend, gap decreasing. structure good connectivity, accessibility, robustness with correlations all spillover effects are significant, showing polarization, such as Shanghai, Suzhou, Hangzhou occupying core position QAP shows affected distance between levels development economy information dissemination. this study innovatively reveal It could provide valuable insights for corresponding policy measures government sectors firms enhance sustainability regional
