And based on this, it further reveals the regional differences in China's digital economic development and the dynamic evolution characteristics of source and distribution. The purpose of this study is to provide practical experience and effective measures for promoting the coordinated development of digital economy in various regions and narrowing the regional digital divide. The study shows that the level of China's digital economy development has been increasing, and the digital economy has become the main engine of national economic development.

The regional differences in the level of China's digital economy development are mainly due to inter-regional differences, and there is a trend of gradual reduction. There is also a certain degree of ups and downs in the process of regional digital economy development, and its spatial heterogeneity and convergence characteristics need to be further studied.
