摘　　要：采用熵权TOPSIS法测算2014—2020年全球42个国家的数字服务贸易发展指数,以基尼系数等指标衡量一国收入不平等程度,对数字服务贸易发展与全球收入不平等之间的关系及其传导机制进行实证分析。研究发现:数字服务贸易发展显著降低了一国收入不平等程度,经过系列稳健性检验和内生性分析后该结论依然可靠。异质性分析发现,数字服务贸易发展有助于降低高收入群体占有收入份额,提高中间收入群体占有收入份额;有助于降低高收入国家和数字政府建设水平较高国家的不平等程度。机制检验表明,数字服务贸易发展通过改善就业结构、技能结构和提高生产效率三条渠道影响收入不平等程度。The paper measures the digital service trade development index of 42 countries in the world from 2014 to 2020 by entropy weight TOPSIS method,and the income inequality of a country by Gini coefficient and other indicators to make an empirial analysis of the relationship between the development of digital service trade and global income inequality and its transmission mechanism.The study finds that the development of digital service trade significantly reduces the level of income inequality in a country,and the conclusion of series of robustness tests and endo-geneity analysis is still reliable.Heterogeneity analysis shows that the development of digital service trade helps reduce the income share of high-income groups and increase the income share of middle income groups.It can help reduce inequality in high-income countries and countries with high levels of digital government.The mechanism test shows that the development of digital service trade affects the degree of income inequality through three channels of improving employment structure,skill structure and production efficiency.
