The balanced development of ecological quality and residents’ well-being is an important factor in achieving sustainable economic development in rural counties. In order to promote the improvement of the coupling coordination degree between ecology and well-being in rural counties, this study explores the impact mechanism of industrial structural transformation and upgrading on the coupling of ecology and well-being in the Sichuan-Chongqing. A dual-fixed-space Durbin model is constructed to analyze the influence mechanism and spatial interaction effects of industrial transformation and upgrading on the coordination of ecology and well-being. The research indicates: (1) From 2010 to 2020, the overall coordination degree of ecology and well-being in the Sichuan-Chongqing rural counties has steadily increased, with higher coordination in the eastern region and lower coordination in the western region. The growth rate of coordination degree is faster in the east and slower in the west, with significant and increasing differences between the east and west. 2) The coupling coordination degree of ecology and well-being in the Sichuan-Chongqing rural counties has a strong positive spatial spillover effect. (3) The more reasonable the industrial structure, the higher the level of coordinated development in the local and surrounding rural counties. The higher the index of industrial advancement, the better the level of coordinated development locally, but the lower the level of coordinated development in the surrounding areas.
