Digital Trade Reform,Spatial Spillovers,and Urban Economic Resilience——A Quasi-natural Experiment Based on Cross-border E-commerce Comprehensive Pilot Zone
This article takes the pilot policy of cross-border e-commerce comprehensive pilot zones as a quasi-natural experiment,and based on panel data from 287 prefecture level and above cities in Chi-na from 2010 to 2021,constructs DID with multiple time model and spatial DID models to deeply explore the impact effect and mechanism of digital trade reform on urban economic resilience.The research results indicate that:(1)The digital trade reform can significantly enhance the resilience of the urban economy,and this conclusion still holds after robustness tests such as parallel trend test,placebo test,and PSM-DID test.(2)The heterogeneity analysis shows that the impact of digital trade reform on urban economic resilience is characterized by geographical location heterogeneity and development level heterogeneity.The impact on the economic resilience of central cities is greater than that of eastern and western cities,and the impact on the economic resilience of second tier and below cities is significantly higher than that of first tier and new first tier cities.(3)The spatial spillover analysis shows that digital trade reform has a significant positive spatial spillover effect on urban economic resilience,which can effectively promote the synergistic improvement of economic resilience in neighboring cities.Based on the above conclusions,this article proposes corresponding countermeasures and suggestions.
