摘要
随着数字化浪潮席卷全球,数字经济成为推动我国产业结构优化升级的重要动力。文章基于2013—2022年我国30个省份的面板数据,在利用熵值法对我国数字经济发展水平进行测度的基础上,引入中介效应与空间杜宾模型,研究数字经济、科技创新与产业结构优化升级的运行传导机制。研究发现,数字经济对产业结构优化升级具有直接正向效应,在经过一系列稳健性检验后该结论依然成立;从影响机制来看,科技创新作为中介在数字经济影响产业结构优化升级中发挥显著作用;数字经济发展对产业结构优化升级具有正向的空间溢出效应和区域异质性。建议制定区域差异化发展策略,通过科技创新激发数字经济潜力,以促进产业结构全面优化升级,推动我国经济实现高质量发展。
As the wave of digitalization is sweeping across the world,the digital economy has become an im⁃portant driving force for the upgrading of China’s industrial structure.With the panel data from 30 provinciallevel administrative regions in China during 2013-2022,this study employs the entropy method to measure the development of China’s digital economy.Furthermore,the mediating effect and the spatial Tobit model are adopted to probe into the transmission mechanism of the digital economy,scientific and technological innova⁃tion,and industrial structure upgrading.The results show that the digital economy has a direct positive effect on the upgrading of industrial structure,which is still tenable after robustness tests.Scientific and technologi⁃cal innovation mediates the effect of the digital economy on industrial structure upgrading.The development of the digital economy presents regional heterogeneity and has a positive spatial spillover effect on the upgrading of industrial structure.According to the results,the development strategies should be formulated considering regional differences.Scientific and technological innovation should be levered to release the potential of the digital economy and promote the comprehensive upgrading of the industrial structure,thus boosting the highquality development of China’s economy.
