数字贸易赋能新质生产力发展研究

Research on the development of new quality productivity empowered by digital trade

以2014—2022年全国30个省份面板数据作为研究样本,选取经济、贸易相关数据,利用熵值法测度各省份数字贸易综合发展水平和新质生产力发展水平,并建立固定效应模型,实证检验数字贸易对新质生产力的影响效应和作用机制。研究发现:数字贸易对新质生产力水平的提升有显著的正向效应,并且可以通过数字技术创新和产业结构优化升级显著提升新质生产力水平。在异质性检验中,数字贸易发展在东部地区、中部地区、西部地区均对新质生产力产生促进作用,而在东北地区这一表现则不明显。为此要大力发展数字经济和数字贸易,完善数字基础设施建设,加快构建现代化产业体系,为提升新质生产力赋能,推动中国区域经济高质量发展。

This paper takes the panel data of 30 provinces in China from 2014 to 2022 as the research samples,selects economic and trade-related data,uses the entropy method to measure the comprehensive development level of digital trade and the development level of new quality productivity in each province,and establishes a fixed effect model to empirically test the impact and mechanism of digital trade on new quality productivity.It is found that digital trade has a significant positive effect on the improvement of new quality productivity,and can significantly improve the level of new quality productivity through digital technology innovation and industrial structure optimization and upgrading.In the heterogeneity test,the development of digital trade has a promoting effect on new quality productivity in the eastern region,the central region and the western region,while this performance is not obvious in the northeast region.To this end,we should vigorously develop the digital economy and digital trade,improve the construction of digital infrastructure,accelerate the construction of a modern industrial system,so as to improve new quality productivity and promote the high-quality development of China’s regional economy.
