中国数字贸易发展水平测度、区域差异及非均衡性研究

Research on the Development Level, Regional Difference and Imbalance of Digital Trade in China

摘要: 在探讨中国数字贸易发展理论逻辑、内涵及决定因素的基础上，构建了9个方面指标47个具体指标的中国数字贸易发展综合评价体系，并运用Dagum基尼系数方法等方法对2011年至2022年全国30个省份数字贸易发展水平进行系统测算与分析，结果表明：(1) 考察期内，中国数字贸易发展水平呈现逐年上升趋势，但整体发展水平仍有较大提升空间；(2) 中国数字贸易发展存在不均衡性，“数字鸿沟”问题仍需改善；(3) 中国数字贸易发展水平的区域差异主要源于区域间差异，但差异正逐步缩小。本文研究为提升中国数字贸易发展水平，破除数字鸿沟问题，让全社会成员享受数字红利，增加全社会成员福利水平具有重要意义。

Abstract: On the basis of discussing the theoretical logic, connotation and determining factors of China’s digital trade development, this paper constructs a comprehensive evaluation index system of China’s digital trade development with 47 specific indicators in 9 aspects, and calculates the development level of digital trade in 30 provinces in China from 2011 to 2022. The Dagum Gini coefficient method and Kernel density estimation are used to analyze the regional differences and non-equilibrium of China’s digital trade development. The results show that the development level of China’s digital trade shows an increasing trend year by year, but the development level of digital trade is still not high; The imbalance of China’s digital trade development is prominent, and the development of digital trade is faced with the problem of “digital divide”. The regional differences in the development level of China’s digital trade mainly come from inter-regional differences, and are gradually narrowing. The development of digital trade in the country and the three major regional provinces has the characteristics of non-equilibrium, and the polarization phenomenon appears in the central part. This study is of great significance to improve the development level of China’s digital trade, break the digital divide, let all members of society enjoy digital dividends, and increase the welfare level of all members of society.
