摘　　要：作为经济发展的关键动力,数字经济在绿色经济中扮演着重要角色。采用2011—2018年中国286个地级及以上城市的数据,利用面板固定效应模型和门槛模型实证探究了中国数字经济发展对城市绿色全要素生产率提高的影响效应和作用机制,并从要素配置效率的角度具体考察了两者之间的影响路径。结果表明,城市数字经济发展有利于提高绿色全要素生产率,主要表现在提高了城市绿色规模效率并促进了绿色技术进步。从区域差异来看,数字经济发展带来的绿色全要素生产率提高主要出现在东部地区、西部地区、政府干预程度较高地区以及数字经济发展水平较高的地区。从要素配置效率来看,资本要素价格扭曲和劳动要素价格扭曲均对数字经济的积极影响产生了抑制效果,且劳动要素价格扭曲存在显著的双门槛效应。当劳动要素价格扭曲程度较高时,数字经济发展对城市绿色全要素生产率提高产生了积极影响。As a key driver of economic development,the digital economy plays an important role in the green economy.Using data from 286 cities in China at the prefecture level and above from 2011 to 2018,this paper empirically explores the impact of the development of China's digital economy on urban green total factor productivity and the mechanism for that effect.It uses panel fixed-effects and threshold models to specifically examine the impact paths from the perspective of factor allocation efficiency.The study shows that the development of a digital economy can improve urban green total factor productivity,mainly by improving urban green scale efficiency and green technological progress.In terms of regional differences,the improvements in green total factor productivity brought about by the development of the digital economy mainly appear in the eastern and western regions,regions with a relatively high degree of government intervention,and those with a relatively highly developed digital economy.In terms of factor allocation efficiency,both capital factor and labor factor price distortion inhibit the positive impact of the development of the digital economy,and labor factor price distortion has a significant double-threshold effect.When the degree of labor factor price distortion is high,the development of a digital economy has a positive impact on urban green total factor productivity.
