Abstract Based on the panel data of 285 cities in China from 2005 to 2021, this paper examines the influence and mechanism of digital industry agglomeration and local government competition on urban green economy efficiency. The research shows that the agglomeration of digital industry is beneficial to improve the efficiency of urban green economy. However, due to the differences in the level of urban economic development, resource dependence and industrialization, the improving effect of digital industry agglomeration on the efficiency of green economy is more significant in first-and second-tier cities, non-resource-based cities and non-old industrial cities. Mechanism analysis indicates that digital industrial agglomeration can improve the efficiency of urban green economy mainly by promoting the online transformation of residents' lifestyle and the intensive transformation of industrial production mode. Under the effect of local government competition, local government economic competition strengthens the promoting effect of digital industry agglomeration on urban green economic efficiency, but the role of local government innovation competition is not obvious. Governments at all levels should actively promote the development of digital industry agglomeration according to the characteristics of urban development, cultivate new momentum of urban green transformation and development, and fully release the enabling effect of digital industry agglomeration development on the improvement of urban green economic efficiency.
