数字经济与产业结构优化升级:来自中国城市的经验证据

Digital Economy and Industrial Structure Optimization and Upgrading:Empirical Evidence from Chinese Cities

探讨了数字经济推动产业结构优化升级的效应以及背后的机制。基于中国2011-2019年城市级别面板数据构建指标体系,利用主成分分析法测度了数字经济水平,估计了数字经济对于中国城市产业结构优化升级的影响。研究发现:第一,数字经济将会通过影响产业结构合理化和高级化两个方面促进城市产业结构优化升级;第二,数字经济对于城市产业结构升级的影响具有人口规模异质性。据此,提出了政府应加快数字化建设、合理分配数字化资源、着重培养复合型人才等对策建议。

This paper discusses the promoting effect of digital economy on the optimization and upgrading of industrial structure and the mechanism behind it.Principal component analysis(pca)is used to measure the level of digital economy and estimate the impact of digital economy on the optimization and upgrading of urban industrial structure in China.The study found that:first,digital economy will affect the rationalization and high-level of industrial structure to promote the upgrading of urban industrial structure.Second,the digital economy has population size for the influence of urban industrial structure upgrade heterogeneity.On this basis,puts forward the government should accelerate the construction of digital,reasonable distribution of digital resources,focus on cultivating inter-disciplinary talent etc.Countermeasures and Suggestions.
