数字贸易对产业结构升级的影响研究

Research on the influence of digital trade on industrial structure upgrading

数字贸易是科技发展赋能国际贸易的结果,对推动国家经济发展、产业结构升级发挥重要作用。本文在技术进步、数字资源禀赋、国际贸易和物流四维分析框架下,阐释数字贸易对产业结构升级的影响机理,并基于2001-2019年中国省际面板数据进行实证检验。研究发现:(1)数字贸易对产业结构升级具有明显的促进作用,但存在影响的区域异质性,对中部地区促进作用最强,东部地区次之,西部地区最弱;(2)从影响路径上来看,数字贸易主要通过技术进步、数字资源禀赋比较优势转换、国际贸易和物流路径促进产业结构升级。基于此,提出加大对数字贸易发展的支持力度、加快数字技术赋能产业的速度、建设现代物流业以改善贸易结构等建议。

Digital trade is the result of international trade enabled by the development of science and technology, and plays an important role in promoting national economic development and upgrading of industrial structure. Based on the four-dimensional analysis framework of technological progress, digital resource endowment, international trade and logistics, this paper explains the impact mechanism of digital trade on industrial structure upgrading, and conducts an empirical test based on China’s inter-provincial panel data from 2001 to 2019. The results show that :(1) digital trade has a significant promotion effect on industrial structure upgrading, but there is regional heterogeneity of the impact.The promotion effect is the strongest in the central region, followed by the eastern region, and the weakest in the western region.(2) From the perspective of impact path, digital trade mainly promotes industrial structure upgrading through technological progress, conversion of comparative advantage of digital resource endowment, international trade and logistics path. Based on this, some suggestions are put forward, such as strengthening the support for the development of digital trade, speeding up the speed of digital technology enabling industry, and building modern logistics industry to improve the trade structure.
