Coupling Coordination Measurement and Obstacle Diagnosis of New Urbanization and Rural Revitalization in the Basin Area of Sichuan Province, China

The coupling coordination of new urbanization (NU) and rural revitalization (RR) is the key research that focuses on promoting integrated development between urban and rural areas. The entropy weight method, coupling coordination model, and obstacle model were used to explore the development level, coupling coordination degree, and obstacle factors of NU and RR in the basin area of Sichuan Province from 2013 to 2021 in this study. The results show the following: The levels of NU and RR in the basin area of Sichuan Province show an uptrend. Central cities exhibit higher levels of RR and NU. Under the influence of a central city, regional central cities have obvious growth in RR and NU. There are fluctuations in the RR and NU indicators in node cities. The coupling coordination degree of NU and RR in the basin area of Sichuan Province continues to rise, and the coordination levels are mainly basic coordination and moderate coordination. The coupling coordination degree is higher in central and regional central cities, while the coupling coordination degree of node cities is relatively lower. The levels of agricultural modernization, public infrastructure and medical resources, and rural governance are the main factors influencing the coupling coordination of NU and RR in the basin area of Sichuan Province. Affected by terrain, economy, and other factors, the level of urban–rural integration in the basin area of Sichuan Province is obviously different. With the continuous improvement of policies, the coupling coordination level of NU and RR is gradually developing towards a positive trend.
