Abstract: Based on the panel data of 169 counties in the Yangtze River Delta from 2015 to 2022, a county-level economic resilience index system was constructed, and a two-way fixed-effect model and an intermediary effect model were used to empirically test the impact of digital inclusive finance on county-level economic resilience and its mechanism. Combined with the uniqueness of the county economy in the Yangtze River Delta, the characteristics of regional heterogeneity are discussed from multiple dimensions such as the level of county economic development and the degree of development of primary and tertiary industries. The results show that digital inclusive finance significantly improves the level of county economic resilience by enhancing the ability of economic adaptation and adjustment, improving the ability of innovation and transformation, and narrowing the income gap between urban and rural areas, and this promotion effect is more prominent in counties with underdeveloped economy, low agricultural dependence and high industrial sophistication. Based on the research findings, it is recommended to implement a gradient digital finance supply strategy to enhance the resilience of the industrial chain, establish a dynamic adjustment mechanism for urban and rural income to stimulate rural vitality, promote the deep integration of digital finance and industrial upgrading, and build a cross-regional coordinated development network to improve the policy effect evaluation system.
