摘　　要：推动经济社会绿色化、低碳化转型,是实现高质量发展的关键环节和解决我国资源环境生态问题的基础之策。在加强生态文明建设、推进绿色低碳发展的背景下,电子商务为城市实现内涵式、集约型、绿色化的经济高质量发展提供了新思路。基于283个城市的面板数据,以国家电子商务示范城市建设为准自然实验,运用多期双重差分模型,探究电子商务政策对城市绿色生态效率的影响及其作用机制。结论如下:电子商务政策显著提升了城市绿色生态效率,在经过了平行趋势检验、安慰剂检验、工具变量方法等一系列稳健性检验后,结论依然成立;空间双重差分模型的研究结果显示,电子商务政策对邻近地区的绿色生态效率存在正向空间溢出效应;机制分析结果表明,电子商务政策通过促进技术创新和产业结构升级来提升绿色生态效率;进一步分析表明,电子商务政策因城市区位及资源禀赋差异而对绿色生态效率的影响存在异质性,且东中部地区、非资源型城市的影响效应更为明显。研究对于加快城市经济绿色转型、推动经济社会可持续高质量发展等具有重要意义。Against the backdrop of strengthening ecological civilization construction and pro-moting green and low-carbon development,cities are exploring a green development path that balances ecological environment and economic growth to improve their green ecological effi-ciency.E-commerce,which is the electronic form of traditional business activities based on in-formation technology and big data,is playing a significant role in this endeavor.Covering various aspects of traditional commerce in digital platforms,it is creating a new retail model that inte-grates online and offline collaboration,offering new ideas for cities to achieve high-quality eco-nomic development that is connotative,intensive,and green.This research is based on panel data from 283 cities,using the construction of national E-commerce demonstration cities as a quasi-natural experiment.Difference-in-differences(DID)with multiple time periods models,spatial econometric models,mediating effect models,etc.are used to explore the impact and mechanism of E-commerce policies on urban green ecological efficiency.The research results indicate that E-commerce policies have significantly improved urban green ecological effi-ciency.The results have been validated through robustness tests such as parallel trend tests,pla-cebo tests,and instrumental variable methods.The spatial effect analysis found that e-commerce policies not only improve the green ecological efficiency of the local area but also have positive spatial spillover effects on the green ecological efficiency of adjacent areas.The mechanism analysis results indicate that E-commerce policies enhance urban green ecological efficiency by promoting technological innovation and industrial structure upgrading.Heterogene-ity testing found that the impact of E-commerce policies on green ecological efficiency varies due to differences in urban location and resource endowment.The impact is more pronounced in the eastern and central regions and non-resource-based cities and has a significant improve-ment effect
