Spatial evolution and differences in driving factors of tourism dual circulation market efficiency in China.

To explore the heterogeneity of development differences and driving factors in the tourism dual-circulation market, this issue uses the Super-DEA algorithm to measure the efficiency of the tourism industry within and outside the 31 provinces in China, and investigates the spatiotemporal evolution of tourism dual circulation market efficiency by using conditional kernel density method and GIS spatial analysis. Through the Geodetector tool, we analyze the differences in the driving factors of tourism internal and external market. The results showed that: (1) In terms of static spatial structure, the difference in tourism market efficiency inside and outside China presents a regional segmentation phenomenon, with smaller differences in the east and the largest differences in the central region. (2) In terms of dynamic spatial evolution, the gravity center of tourism internal and external market efficiency is shifting to the southwest, and there appears a polarization phenomenon between low-efficiency areas and high-efficiency areas. (3) In terms of driving factors, factors at the product supply level are key to promoting efficient development in both domestic and international markets. Tourism products and supporting facilities play an important role in both markets. At the government behavior guidance level, the role of marketization and information technology in promoting the external circulation market is greater than that of the internal circulation.
