摘　　要：基于我国数字技术快速发展以及“双碳”目标的背景,本文将“宽带中国”试点政策作为准自然实验,使用2007—2019年278个地级市的面板数据,通过构建渐进双重差分模型、空间杜宾双重差分模型来考察“宽带中国”试点政策对经济绿色转型的影响。研究发现:“宽带中国”试点政策能够促进我国经济实现全面绿色转型;并且这种促进作用在不同资源禀赋、不同环境污染、不同地理区域的城市中表现出异质性。进一步机制检验结果表明,“宽带中国”试点政策主要是通过促进绿色创新能力的提升、推动城市产业结构升级来实现经济绿色转型。空间溢出效应检验显示,“宽带中国”试点政策还会对周边邻近地区的经济绿色转型产生正向空间溢出效应,即带动周边邻近地区的经济实现绿色转型。本文研究为建设数字中国以推动我国经济实现全面绿色转型提供了一定的参考。Based on the background of the rapid development of digital technology and the "Dual Carbon Goals" in China, this paper takes the pilot policy of "Broadband China" as a quasi-natural experiment. Using the panel data of 278 prefecture-level cities from 2007 to 2019,this paper examines the impact of the pilot policy of "Broadband China" on the green economic transformation by constructing a progressive difference difference model and a spatial Dubin Difference difference model. The results show that the pilot policy of "Broadband China" can promote the comprehensive green transformation of Chinese economy;And the promotion effect is heterogeneous in cities with different resource endowments, different environmental pollution and different geographical regions. The further mechanism test results show that the pilot policy of "Broadband China" mainly realizes the green economic transformation by promoting the improvement of green innovation ability and promoting the upgrading of urban industrial structure. The test of spatial spillover effect shows that the pilot policy of "Broadband China" will also have positive spatial spillover effect on the economic green transformation of neighboring areas, that is, drive the economic green transformation of neighboring areas. This paper provides some reference for the construction of digital China to promote the comprehensive green transformation of Chinese economy.
