Abstract: Based on the 2013-2022 data of the cities in Chengdu-Chongqing Twin-city economic circle, the entropy weight TOPSIS method, Dagum’s Gini coefficient, Kernal kernel density estimation, and dynamic QCA and NCA are applied to explore the dynamic evolution of the high-quality development level in the region and the factors affecting it. The study shows that: from 2013 to 2022, the level of high-quality development in the region as a whole shows an upward trend, but the development is slow and is still at a relatively low stage of development; the level of high-quality development in the region shows a significant dynamic trend of change, and the cities with a higher level of development are mainly concentrated in the “double cores” surroundings. Around the neighborhood, the neighborhood background of the cities of the spatial spillover effect is obvious, part of the high level of the city there is a siphon effect; the region’s high-quality development can be divided into five types of grouping paths, can be refined into economic innovation and coordination of efficiency, economic coordination of green and open drive type and the new development concept of upgrading type, Chengdu-Chongqing “double cores” of the periphery of the city by the economic innovation coordination. The neighboring cities of Chengdu-Chongqing “double cores” are affected by the economic innovation and coordination efficiency type, and the other cities are mostly affected by the new development concept upgrading type.
