Research on the Time Evolution of Digital Economy Development Level and Interregional Differences and Correlation
As one of the complex systems,the digital economy system exhibits complex characteristics through the interaction of various subsystems.Simulating and exploring its evolution trend,as well as the differences and correla-tions between subsystems,is of great significance for studying the development laws of the digital economy.Taking the digital economy system of Zhejiang Province from 2017 to 2021 as the research object,the temporal evolution charac-teristics of regional digital economy based on Kernel kernel density estimation were analyzed first,then the Dagum Gi-ni coefficient was introduced to mine the regional differences of digital economy,and the gravity model and social net-work was used to analyze the interregional digital economy correlation.The results show that the number of cities with a high development level of digital economy is gradually increasing,but regional heterogeneity and imbalance charac-teristics emerge,and this imbalance mainly comes from inter-regional,and the contribution of intra-regional cities is small.The internal cities in the more developed regions of the digital economy are closely connected,and the spillover effect is significant.
