数字经济对产业结构升级的影响及空间效应

The Impact and Spatial Effect of Digital Economy on Industrial Structure Upgrading

数字经济不仅是经济增长的新动能,也是产业结构升级的新引擎。基于2011—2020年30个省份的数据,从产业结构高级化、合理化的双重视角出发,使用熵值法测度各省数字经济发展水平,并从基准回归-中介效应-空间效应3个模块围绕数字经济对产业结构升级的影响展开研究。结果表明:数字经济促进产业结构升级;居民消费扩容在两者促进机制中起到部分中介作用;数字经济对产业结构高级化具有正向空间溢出效应,而对产业结构合理化的空间溢出效应还未体现。

Digital economy is not only the new power of economic growth,but also the new engine of industrial structure upgrading.Based on the data of 30 provinces from 2011 to 2020,from the dual perspectives of the advanced and rationalized industrial structure,the development le-vel of digital economy in each province is measured by using the entropy method.The impact of digital economy on industrial structure upgrading is studied from the three modules of benchmark regression-intermediary effects-spatial effects.The results show that the digital economy promotes the upgrading of industrial structure,the expansion of household consumption plays a part of the intermediary role in the promotion mechanism of both,and the digital economy has a positive spatial spillover effect on the upgrading of industrial structure.However,the spatial spillover effect on the rationalization of industrial structure has not yet been manifested.
