摘　　要：以国家电子商务示范城市建设作为准自然实验,采用最新交叠双重差分模型,实证分析电子商务示范城市建设对城市服务业结构升级的直接和空间溢出影响。研究表明:电商城市试点政策对服务业结构升级有显著的促进作用,且正向效应在东部地区、大规模城市和珠三角城市群城市中更为明显;试点政策通过技术效应、渠道效应和需求效应对服务业结构升级产生影响;电商城市试点政策对非示范城市服务业结构升级存在正向溢出效应,且最优溢出距离约为100千米。Taking the construction of national e-commerce demonstration cities(NEDC)as a quasi-natural experiment,the paper employed the latest staggered difference-in-differences model to empirically analyze the direct and spatial spillover effects of NEDC on the structural upgrading of urban service industry.The study showed that:the pilot policy of e-commerce cities significantly contributed to the structural upgrading of the service industry.This positive effect was more obvious in the eastern region,large-scale cities,and the cities located in the Pearl River Delta urban agglomeration.Mediating factors in this relation included the technological effect,the channel effect and the demand effect.In addition,NEDC had a positive spillover effect on the structural upgrading of the service industry in non-demonstration cities,and the optimal spillover distance was approximately 100 kilometers.
