数字政策对城市经济韧性的影响研究

The Research on the Impact of Digital Policies on Urban Economic Resilience

基于2013—2022年30个省份面板数据,利用PSM-DID模型分析了不同城市数字政策制定对城市经济韧性影响,同时分析了环境规制和产业数字化转型在数字政策促进城市经济韧性提升过程中的作用.研究结果表明:数字政策执行对城市经济韧性具有显著的正向效应,在沿海地区中的效应要强于在内陆地区中的效应.产业数字化转型在数字政策对城市经济韧性的影响中起着中介作用,且存在一定的非线性效应;在较高的产业数字化转型水平下,数字政策促进城市经济韧性提升的效应更为显著;环境规制在数字政策促进城市经济韧性提升的过程中发挥着动态调节作用,即在环境规制执行前期,数字政策不利于城市经济韧性提升,而在环境规制执行后期,数字政策对城市经济韧性起着积极的促进作用.

Based on panel data from 30 provinces from 2013 to 2022,the PSM-DID model is used to systematically analyze the impact of digital policy formulation in different cities on urban economic resilience.At the same time,the roles of environmental regulations and industrial digital transformation in promoting urban economic resilience through digital policies are analyzed.The results show that the implementation of digital policies has a significant positive effect on urban economic resilience,which is stronger in coastal areas than in inland areas.The digital transformation of industries plays a mediating role in the impact of digital policies on urban economic resilience,and there is a certain non-linear effect.At a higher level of industrial digital transformation,the effect of digital policies on enhancing urban economic resilience is more significant.Environmental regulations play a dynamic regulatory role in promoting urban economic resilience through digital policies.In the early stages of environmental regulation implementation,digital policies are not conducive to improving urban economic resilience,while in the later stages of environmental regulation implementation,digital policies play a positive role in promoting urban economic resi-lience.
