摘　　要：文章基于2011—2021年省级面板数据,采用面板回归模型与门限回归模型实证分析了数字经济驱动产业结构升级的机制与特征,得出如下结论:(1)数字经济能够显著驱动产业结构升级,但存在明显的区域差异;(2)数字经济对产业结构升级的驱动效应存在其自身发展水平的门限效应,而且随着数字经济发展水平的提高,其对产业结构升级的影响呈现边际效应递减的特征;(3)促进人力资本深化可以应对数字经济对产业结构升级影响的边际效应递减问题。Based on the provincial panel data from 2011 to 2021,this paper empirically analyzes the mechanism and characteristics of industrial structure upgrading driven by digital economy by using panel regression model and threshold regression model,and draws the following conclusions:(1)Digital economy can significantly drive the upgrading of industrial structure,but its driving effect has significant regional differences.(2)The driving effect of digital economy on industrial structure upgrading has its own threshold effect of development level.With the improvement of the development level of digital economy,the impact of digital economy on the upgrading of industrial structure shows a decreasing marginal effect.(3)Promoting the deepening of human capital can deal with the diminishing marginal effect of digital economy on the upgrading of industrial structure.
