Study on Synergistic Development and Dynamic Evolution of Internal Systems in Rural Revitalization: Based on PVAR Model and Kernel Density Estimation Method

Using entropy method, descriptive statistics, PVAR model, Kernel density estimation and other methods, this paper systematically measured the level of synergistic development and dynamic evolution process of the internal systems of rural revitalization by using the data of China’ s localities and municipalities in the period of 2000—2022. The study showed that, the coordinated development among the subsystems of rural revitalization jointly promoted the effective implementation of the rural revitalization strategy. The comprehensive development level of rural revitalization was multi-polarized, multi-peaked and trailing right, but the development level of each subsystem was basically consistent with the dynamic evolution of the comprehensive development level of rural revitalization, indicating that although there were some differences in the level of rural revitalization and the development level of its sub-systems in China, the various sub-systems of rural revitalization were able to develop in coordination and promote the effective implementation of the strategy of rural revitalization together.
