数字化转型、出口开放与产业结构升级

Digital Transformation,Export Opening and Industrial Structure Upgrading——Empirical test based on mediation effect

数字经济时代的数字化转型是推动出口贸易高质量发展,促进产业结构协同升级的重要手段。基于2011—2019年中国省际层面面板数据,对数字技术发展、出口开放以及产业结构升级之间的传导机制进行研究。结果表明:数字技术发展能够通过影响出口开放进而影响产业结构优化升级;从区域视角来看,分地理结构的区域异质性显示,出口贸易的中介效应在东中部地区显著为负,在西部地区并不显著;分技术产业水平的区域异质性显示,出口贸易的中介效应在低技术产业水平区域显著为负,在高技术产业水平区域不显著。为推进我国产业结构优化升级,需要加快新型数字技术基础设施建设,因地制宜,不断完善产业政策与和贸易政策,精准补齐区域发展不平衡的短板,构建以合作共赢为核心的新型国际规则体系。

Digital transformation in the digital economy era is an important means to promote the high-quality development of export trade and lead to the coordinated upgrade of the industrial structure.In view of this,this paper studies the transmission mechanism between digital technology development,export opening,and industrial structure upgrading based on panel data at the inter-provincial level in China from 2011 to 2019.The results show that the development of digital technology can affect the optimization and upgrading of the industrial structure by affecting the opening of exports.From a regional perspective,the regional heterogeneity by geographical structure shows that the mediating effect of export trade is significantly negative in the eastern and central regions,but not in the western regions.The regional heterogeneity by technology industry level shows that the mediating effect of export trade is significantly negative in the low-tech industry level area,but not significant in the high-tech industry level area.In order to promote the optimization and upgrading of my country's industrial structure,it is necessary to speed up the construction of new digital technology infrastructure.All localities continue to improve industrial policies and trade policies according to local conditions,accurately fill in the shortcomings of unbalanced regional development,and build new international rules centered on win-win cooperation system.
