数字经济对产业结构优化升级的影响研究——基于山东省16个地市面板数据

On the Impact of Digital Economy on the Optimization and Upgrading of Industrial Structure--Based on Panel Data From 16 Cities in Shandong Province

数字经济的蓬勃发展,为产业结构优化升级提供了新动能。文章基于2014—2019年山东省16个地级市面板数据,运用熵值法测度数字经济发展水平,通过固定效应模型分析数字经济对产业结构优化升级的影响效应。研究结果表明:(1)数字经济能够对产业结构优化升级产生积极影响,且这一结论通过了稳健性检验;(2)数字经济对产业结构优化升级的促进效应在经济发展水平较高的地市更为显著。据此,山东省应加快数字经济建设,通过数字经济赋能产业结构调整,实现产业结构优化升级。

The vigorous development of the digital economy has provided new impetus for the optimization and upgrading of industrial structure.The article is based on panel data from 16 prefecture level cities in Shandong Province from 2014 to 2019,using the entropy method to measure the level of digital economy development,and analyzing the impact of digital economy on industrial structure optimization and upgrading through a fixed effects model.The research results indicate that:(1)the digital economy can have a positive impact on the optimization and upgrading of industrial structure,and this conclusion has passed the robustness test;(2)the promotion effect of the digital economy on the optimization and upgrading of industrial structure is more significant in cities with higher levels of economic development.Based on this,Shandong Province should accelerate the construction of the digital economy,empower industrial structure adjustment through the digital economy,and achieve industrial structure optimization and upgrading.
