As the cornerstone and driving force for the vigorous development of the digital economy, digital infrastructure is playing an increasingly important role in enhancing the resilience of urban economies. Using panel data from 271 cities in China from 2008 to 2022, this study examines the impact of digital infrastructure on urban economic resilience using a double fixed-effect model, a mediator-effect model, and a spatial Durbin model. The empirical results show that digital infrastructure not only directly has a significant positive impact on urban economic resilience, but also injects new momentum into urban economic resilience by stimulating innovation and entrepreneurship activity. In addition, the spatial effect analysis further shows that the positive impact of digital infrastructure on urban economic resilience has a positive spillover effect across geographical boundaries. Heterogeneity analysis shows that compared with the central and western regions and small and medium-sized cities, the eastern region and large cities have more prominent performance in the enabling effect of digital infrastructure construction on economic resilience. The results of this study provide a solid theoretical support and practical reference for giving full play to the potential of digital infrastructure and promoting the overall improvement of urban economic resilience. %K 数字基础设施， %K 创新创业活跃度， %K 城市经济韧性， %K 空间溢出
