Regional Differences and Driving Factors of Coupled Coordinated Development of Digital Economy and Rural Revitalization

Based on the panel data of 11 provinces (municipalities) in the Yangtze River Economic Belt from 2011 to 2021, the coupled coordination degree of digital economy and rural revitalization was measured by entropy method and coupled coordination degree model.The difference of regional coupling coordination was studied by Dagum Gini coefficient decomposition, and the driving factors of the development of the two coupling coordination were studied by grey relational degree model. It is found that as time goes by, the stage of coupled and coordinated development of the Yangtze River Economic Belt continues to improve. In 2011, most areas are still in the stage of serious imbalance, and by 2021, there will be no areas in the stage of imbalance. The gap between the river basins is the main reason for the uncoordinated coupling development of the Yangtze River Economic Belt. The influence of each driving factor on the coupling coordination degree is spatially different, and the correlation degree of each driving factor is government regulation, industrial structure, innovation drive, economic drive and human capital in order from large to small.
