Abstract：This paper measures and analyzes the input-output efficiency and causes of digital economy in the Yangtze River economic belt from 2010 to 2019 through DEA-Malmquist index,and evaluates the regional differences and dynamic evolution trend of digital economy output efficiency in the region by using Dagum Gini Coefficient,Kernel Density Estimation,Moran Index and Markov Chain.The empirical results found that the output efficiency and growth rate of digital economy in the upper,middle and lower regions of the Yangtze River showed different characteristics.And the innovation,diffusion and introduction of technology significantly promoted the development of digital economy in the Yangtze River economic belt.Regional differences were the main source of the overall differences in the Yangtze River economic belt,and there was no significant spatial correlation between regions.Compared with the upper regions and lower regions,the digital economic efficiency in the middle regions of the Yangtze River was less likely to remain stable,and a downward trend of the high-level efficiency was presented.Based on this,suggestions were put forward,such as promoting technological progress,implementing differentiated digital economy development policies and building a regional coordinated development mechanism in the upper,middle and lower regions of the Yangtze River.The research results and conclusions have important practical significance for promoting the green circular low-carbon development of the Yangtze River economic belt,creating the new advantages of regional innovation-driven development,and promoting regional coordinated development.
