Exploring the Driving Effect of Policies on Cultural-Tourism Integration Levels: A Difference-in-Differences Approach
摘要
Drawing on industry convergence theory, this study develops an evaluation index system to quantify cultural-tourism integration. It applies the entropy weight method and a multiple-linear comprehensive index approach to measure both the levels and the spatiotemporal dynamics of culture-tourism integration in 31 selected Chinese provinces (municipalities and autonomous regions) from 2010 to 2022. A staggered Difference-in-Differences model is then used to estimate the driving effects of integration policies and to uncover the pathways. The results show a steady upward trend in integration, marked regional disparities consistent with a Matthew effect, and a significant overall policy effect on integration levels, with notable heterogeneity across regions. Pathways analysis indicates that policies primarily enhance resource and market integration and that the pathways of policies also influence differ by region. This study advances understanding of how policy drives cultural-tourism integration and provides guidance for promoting high-quality, balanced regional development of culture-tourism.
