摘要
文章基于地级以上城市数据,实证检验了数字经济发展对城市绿色全要素生产率的影响。研究显示:数字经济发展对城市绿色全要素生产率具有显著促进作用;中介效应检验发现数字经济发展对城市产业结构高度化具有显著正向影响,但对城市产业结构合理化的影响不显著;数字经济发展是通过推动产业结构高级化而非产业结构合理化促进城市GTFP。
Based on the data of cities above the prefecture level, this paper empirically tests the influence of digital economy development on urban green total factor productivity. The study shows that the development of digital economy significantly promotes urban green total factor productivity;the intermediary effect test shows that the development of digital economy has significant positive influence on urban industrial structure, but not the rationalization of urban industrial structure;the development of digital economy promotes urban GTFP through the rationalization of industrial structure.
