数字经济对产业结构升级的影响研究——基于省级面板数据的实证分析

Research on the Impact of the Digital Economy on the Upgrading of Industrial Structure——Empirical Analysis Based on Provincial Panel Data

随着新一轮科技革命和产业革命的兴起,新技术、新产业、新业态、新模式层出不穷,传统产业被深刻重塑,新兴产业蓬勃发展,新动能快速崛起。基于2011—2020年省级面板数据,探究数字经济对产业结构升级的影响。利用主成分分析法对数字经济进行测度,并以创新投入作为中介机制进行分析。研究结果表明:数字经济对产业结构升级具有正向影响,并且创新投入的提高是数字经济促进产业结构升级的关键机制。进一步分析发现,数字经济对产业结构升级的推动作用存在区域异质性。具体而言,数字经济对东部地区和西部地区均产生了正向的积极作用,但与东部地区相比,西部地区表现出“后发优势”。

With the rise of a new round of technological and industrial revolutions,new technologies,in-dustries,business models,and patterns are emerging one after another.Traditional industries are being deeply reshaped,emerging industries are thriving,and new dynamic forces are rapidly rising.Exploring the impact of the digital economy on the upgrading of industrial structure based on provincial panel data from 2011 to 2020.Measure the digital economy using principal component analysis and analyze with in-novation input as an intermediary mechanism.The research findings indicate that the digital economy has a positive impact on the upgrading of industrial structure,and the increase in innovation input is the key mechanism through which the digital economy promotes the upgrading of industrial structure.Further anal-ysis reveals that the driving effect of the digital economy on the upgrading of industrial structure exhibits characteristics of regional heterogeneity.Specifically,the digital economy has had a positive impact on both the eastern and western regions,but compared to the eastern region,the western region has shown a"late-mover advantage".
