Under the background of urban-rural integration development， in order to solve the urban-rural dual structure， comprehensively promote the modernization of agriculture and rural areas， and optimize the allocation of urban and rural resources， taking the Chengdu Plain economic zone as an example， this paper constructs the evaluation index system of rural revitalization and the evaluation index system of new urbanization， and comprehensively uses the combination weighting method， coupling coordination degree model， obstacle degree analysis and other methods to analyze the level of rural revitalization， the level of new urbanization， the spatial and temporal evolution of the coupling and coordination between rural revitalization and new urbanization， and the obstacle factors of rural revitalization and new urbanization in the Chengdu Plain Economic Zone from 2013 to 2022. The results show that：（1） The level of rural revitalization and new urbanization in the study area is constantly improving. The average annual growth rates of the comprehensive index are 3.03% and 2.07%， respectively， but the development is relatively unbalanced， showing a spatial differentiation pattern of ''high in the middle and low around''；（2） The coupling coordination degree of rural revitalization and new urbanization has evolved from ''serious imbalance'' in 2013 to ''basic coordination'' in 2022， among which Chengdu is the first to achieve ''high-quality coordination''；（3） The main obstacle factors of rural revitalization and new urbanization show systematic differences. The frequency of afforestation area， research and development expenditure （R&D expenditure ） accounted for the proportion of regional GDP， the number of rural cultural stations and the area of urban construction land are higher. These obstacle factors reveal the core crux of the lack of overall ecological governance efficiency， insufficient support for innovation ability， and imbalance of spatial resource allocation in the region.
