Research on the Spatio-temporal Evolution and Regional Differences in the Coupled Coordination of Rural Revitalization and Common Prosperity
The dynamic coupled coordination relationship between the two subsystems of rural revitalization and common prosperity from 2010 to 2019 was analyzed by constructing an evaluation index system for ru-ral revitalization and common prosperity,and comprehensively applying the coupled coordination model,entropy value method,kernel density estimation,Theil index and other methods.The results show that during the period from 2010 to 2019,the overall level and degree of coupled coordination between rural re-vitalization and common prosperity in China generally exhibit an upward trend and spatial imbalance,with a characteristic spatial distribution of"strong in the east and weak in the west".The overall difference of the degree of coupled coordination between rural revitalization and common prosperity is gradually shrink-ing,and it exhibits a stage characteristic with 2015 as the demarcation point.The degree of coupled coor-dination demonstrates a significant positive spatial correlation,and most provinces experience notable changes in their spatial distribution during the sample period.
