摘　　要：数字经济时代,新一代信息技术与城市建设的有机融合有利于克服集聚经济的负外部性,产生良好的生态效应。基于三批国家智慧城市试点建设名单,运用准自然实验的研究手段,旨在评估智慧城市建设的生态效应及异质性,并探讨其间的作用机制。研究发现,智慧城市建设显著推动了城市在环境、经济和社会等领域的生态化发展,从而提升城市生态健康水平。机制检验表明,智慧城市建设通过推动污染企业退出、激励绿色技术创新、促进人力资本积累三个渠道来发挥积极的生态效应。In the age of digital economy,the organic integration of the new generation of information technology and urban construction is conducive to overcoming the negative externalities of agglomeration economy and producing good ecological effects.This article is based on the list of national pilot projects for smart city construction,and uses various methods such as propensity score matching double difference(PSM-DID)to evaluate the ecological effects of smart city construction.The research indicates that the construction of smart cities significantly promotes the ecological development of cities in the fields of environment,economy,and society,thereby improving the level of urban ecological health.The mechanism test shows that smart city construction has positive ecological effects through three channels:promoting the exit of polluting enterprises,stimulating green technology innovation,and promoting human capital accumulation.
