Against the backdrop of increasing global political and economic uncertainties,enhancing regional economic resilience has become a key focus of regional development.Green technology innova-tion,as a critical driver of high-quality urban development and economic transformation,has an un-clear impact on regional economic resilience.From the perspective of the green technology innovation value chain,this study employs panel data from 283 prefecture-level and above cities in China during 2004-2022 to theoretically and empirically examine the multidimensional effects and mechanisms of green technology innovation on urban economic resilience.The findings reveal that:1)green technology innovation enhances economic resilience by promoting technological upgrading,optimizing industrial structure,and fostering the coordinated development of the"economy-society-ecology"sys-tem.2)From 2004 to 2022,the level of green technology innovation in Chinese cities continued to rise,showing a spatial pattern of"Eastern leadership,Central rise,and Western catch-up".Mean-while,urban economic resilience evolved from"clear local advantages"toward"overall improvement accompanied by intensified internal differentiation".3)Green technology innovation significantly pro-motes urban economic resilience in China,demonstrating a U-shaped effect,and this conclusion holds under robustness tests.4)Spatial effect tests confirm that green technology innovation has a posi-tive spatial spillover effect on economic resilience.Based on these findings,this study proposes governance pathways for regional economic resilience that deeply integrate green technology innovation with the real economy,aiming to enhance cities'ability to cope with external shocks,narrow regional resilience gaps,and achieve high-quality economic development.
