Empirical analysis of enabling high-quality development of digital economy based on grey correlation degree and Moran's I index

The index system of digital economy and high-quality development is constructed from multiple dimensions, and the development index of digital economy and high-quality development index are measured by entropy weight method. The correlation between digital economy and high-quality development is analyzed by using grey relational degree, and the spatial correlation characteristics of the two are analyzed by Moran's I index. The study found that the development level and high quality of our country's digital economy show an increasing trend of fluctuation, and the regional difference is obvious. The digital economy is highly correlated with high-quality development, with significant regional heterogeneity and spatial correlation characteristics. We should vigorously develop the digital economy and promote high-quality development.
