摘要
数字经济作为新质生产力的主要构件,是外贸高质量发展的关键动力,但是,是否已经赋能中国外贸的高质量发展并产生了实质性的经济效应,是一个值得经验研究的问题。本文基于中国30个省级的2011—2020年经验数据,构建面板回归模型讨论了数字经济对外贸高质量发展的影响,并进一步利用产业结构升级和研发创新对于外贸高质量发展的中介效应模型,实证检验了数字经济对外贸高质量发展的机制路径,最后说明了不同省份的外贸高质量发展对低附加值制造业出口的脱钩程度。结果表明,中国的数字经济正向促进外贸高质量的发展,但是存在区域异质性,根据数字经济对外贸高质量的影响强度由高到低依次是东部、中部和西部。进一步来看,数字经济可以通过产业结构升级和研发创新的中介效应正向促进外贸的高质量发展,然而,我国多数省份的外贸高质量增长对低附加值制造业出口脱钩。
The digital economy,as the main building block of the new quality productivity,is a key driving force for the high⁃quality development of foreign trade,but whether it has empowered the high⁃quality development of China's foreign trade and produced substantial economic effects is a question worthy of empirical research.Based on the 2011—2020 empirical data of 30 Chinese provinces,this paper constructs a panel regression model to discuss the impact of the digital economy on the high⁃quality development of foreign trade,and further empirically examines the path of the mechanism of the digital economy on the high⁃quality development of foreign trade using a model of the mediating effect of industrial structure upgrading and R&D innovation on the high⁃quality development of foreign trade,and finally illustrates how the high⁃quality development of foreign trade in different provinces has a significant impact on the decoupling degree of low value⁃added manufacturing exports in different provinces.The results show that China's digital economy positively promotes the development of high quality of foreign trade,but there is regional heterogeneity,according to the intensity of the impact of the digital economy on the high quality of foreign trade from high to low is the east,central and west,furthermore,the digital economy can positively promote the development of high quality of foreign trade through the mediating effect of the upgrading of the industrial structure and the R&D and innovation,however,the high quality of the growth of the high quality of foreign trade in the majority of the provinces of China has been decoupled from the high quality of the low value⁃added manufacturing exports decoupled.
