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.展开更多
