Research on the development characteristics and influencing factors of tourism financial efficiency in the Chengdu-Chongqing Twin-City Economic Circle based on DEA-Malmquist and GeoDetector

The Chengdu-Chongqing Twin-City Economic Circle, as an important strategic urban cluster in western China, has made significant achievements in the integration and development of tourism and finance, leveraging its tourism resources and strong financial potential. However, due to limitations in regional resources and economic development, the integration of tourism and finance in this area faces prominent issues, such as significant regional disparities and inefficient mobility between areas. This paper measures the tourism financial efficiency in the Chengdu-Chongqing Twin-City Economic Circle from 2011 to 2019 using the DEA-Malmquist model. After understanding the basic characteristics of tourism-finance integration in the region, the GeoDetector method is applied to calculate the main influencing factors of tourism financial efficiency. Based on the empirical research results, certain recommendations are made to provide decision support for industrial integration in related regions.
