数字经济对产业结构升级的影响研究

Research on the Impact of Digital Economy on Industrial Structure Upgrading

数字经济的发展对产业结构升级产生了十分重要的影响。基于2011—2022年我国省级面板数据,研究数字经济对产业结构升级的作用。研究结果表明:数字经济能够有效促进产业结构整体升级、产业结构高级化和产业结构合理化,进而促进产业结构升级,并且在经过稳健性检验之后上述结论依然成立。但异质性分析表明数字经济在非长江经济带与长江经济带的表现显著性不同,而在中西部地区和东部地区分别表现出促进和阻碍两种作用。进一步建立门槛效应模型发现数字经济发展对于产业结构升级的影响呈现出非线性特征。在此基础上提出完善数字基础设施、加大科技研发投入力度等建议。

The development of the digital economy has had a very important impact on the upgrading of industrial structure.Based on provinciallevel panel data from 2011 to 2022 in China,this study investigates the role of digital economy in upgrading industrial structure.The research results indicate that the digital economy can effectively promote the overall upgrading,advancement and rationalization of the industrial structure,thereby promoting the upgrading of the industrial structure.After robustness testing,the above conclusion still holds.However,heterogeneity analysis shows that the performance of the digital economy is significantly different in the non Yangtze River Economic Belt and the Yangtze River Economic Belt,while it exhibits promoting effect in the central and western regions,and hindering effect in the eastern regions.Further establishing a threshold effect model reveals that the impact of digital economy development on industrial structure upgrading exhibits non-linear characteristics.On this basis,suggestions are proposed to improve digital infrastructure and increase investment in scientific and technological research and development.
