摘　　要：本文探究了数字经济推动制造业转型升级的效应及其内在机制。理论分析表明,数字经济可以通过激发创新活跃度,进而赋能制造业转型升级。实证研究方面,本文基于2010~2020年中国30个省(区、市)的数据,构建了数字经济综合发展水平、创新活跃度和制造业转型升级的指标评价体系,在此基础上进行计量分析。结果表明:数字经济显著促进了制造业转型升级,这一结论在选用制造业合理化指数作为被解释变量以及运用多种回归方法进行稳健性检验后仍成立。作用机制的研究结果表明,激发创新活跃度是数字经济赋能制造业转型升级的重要机制。最后,采用面板门槛回归模型进行分析,发现数字经济的促进作用表现为“边际效应”非线性递增的特点和区域异质性,并且在中部和东部地区的提升作用显著大于西部地区。This paper explores the effect of digital economy on the transformation and upgrading of manufacturing industry and its internal mechanism.Theoretical analysis shows that digital economy can stimulate innovation activity,and then enable the transformation and upgrading of manufacturing industry.In terms of empirical research,based on the data of 30 provinces in China from 2010 to 2020,this paper constructs an index evaluation system for the comprehensive development level of the digital economy,innovation activity and the transformation and upgrading of manufacturing industry,and makes quantitative analysis.The results show that the digital economy has significantly promoted the transformation and upgrading of manufacturing industry.This conclusion is still valid after choosing the rationalization index of manufacturing industry as the explanatory variable and using a variety of regression methods.The results of the mechanism analysis show that stimulating innovation activity is an important approach for the transformation and upgrading of manufacturing industry enabled by the digital economy.Finally,through the panel threshold regression analysis,it is found that the promotion effect of digital economy is characterized by the non-linear increase of“marginal effect”and regional heterogeneity,and the promotion effect in China's central and eastern regions is significantly greater than that in China's western regions.
