Abstract: The coupling coordination degree model，the Dagum Gini coefficient decomposition method，and the spatial Kernel density estimation method are employed to calculate the coupling coordination degree between high-quality financial development and economic resilience，comprehensively reveling their spatiotemporal evolution characteristics；the spatial econometric method is used to study the mechanism and effect of high-quality financial development in empowering economic tenacity. The results show that the coupling and coordination degree between the overall high-quality financial development at the national level and economic resilience is continuously improving；however，regional differences are gradually expanding，and in the spatial aspect，there is a spatial distribution of“high-high”and“low-low”；high-quality financial development can effectively enhance regional economic resilience，but it has a negative spillover effect on adjacent regions. Further analysis suggests that high-quality financial development can significantly mitigate adverse impacts，and an increase of marketization can enhance the hedging intensity of high-quality financial development against adverse shocks，thereby improving economic resilience.
