Abstract: Based on the panel data of 285 prefecture-level cities in China from 2011 to 2021, by constructing a multi- dimensional econometric model system, the impact of digital finance on the export resilience of cities was systematically investigated. The research shows that digital finance has a significant positive impact on the export resilience of Chinese cities, and the impact has a more significant improvement on the export resilience of cities with poor traditional financial endowments. The analysis of regional heterogeneity shows that digital finance in the eastern region has a significantly greater promoting effect on urban export resilience than that in the central and western regions. The intermediary effect test further shows that digital finance can indirectly promote the export resilience of cities by improving the innovation ability of cities and easing financing constraints. The results of spatial measurement show that digital finance and urban export resilience have significant spatial positive correlation and global agglomeration characteristics, and digital finance has a significant positive spatial spillover effect on urban export resilience.

Key words: digital finance; export resilience; urban innovation ability; financing constraints; spatial spillover effect
