Research on the Coupling and Coordinated Development of Digital Economy and Rural Revitalization in the Yangtze River Delta Basin

The Yangtze River Delta basin is an important region for high-quality development in China. Based on the panel data of three provinces and one municipality directly under the Central Government in the Yangtze River Delta basin from 2019 to 2023, the comprehensive evaluation index of the digital economy and rural revitalization in the Yangtze River Delta basin and the coupling coordination degree between them were calculated using the entropy method and the coupling coordination degree model. The results show that the digital economy and rural revitalization in the Yangtze River Delta basin are highly coupled as a whole, and the coordination degree is increasing year by year, but it shows the characteristics of regional differences. Therefore, it is necessary to strengthen digital construction. For the rural areas in the Yangtze River Delta region, digital infrastructure construction is the top priority. Strengthen regional cooperation to achieve high-quality coordinated development of the digital economy and rural revitalization, actively promote integrated construction, strengthen policy support, and achieve balanced development, so as to realize China's modernization development and promote common prosperity.
