Coupling and coordination of provincial new urbanization and high-quality agricultural development in China, 2004-2018

The construction of a new type of urbanization is a necessary path for the development of modern cities, and a powerful support for coordinating the balanced development of urban and rural areas and promoting high-quality agricultural development. Based on the panel data of 30 provinces in China from 2004 to 2018, the article constructs a new urbanization and agricultural high-quality development evaluation system; then using the coupling coordination degree model and the spatial correlation analysis method, the paper empirically tests the coupling coordination of the two systems degree and its spatial relevance. The results of the study show that the average level of coupling and coordination between new urbanization and high-quality agricultural development in the period under study is at a barely coordinated level, with the highest level being moderately coordinated. There are significant inter-regional differences, with a higher level of coupling and coordination in the eastern regions and more room for improvement in the central and western regions. At this stage, the trend of "club convergence" is remarkable, with highhigh agglomeration and low-low agglomeration coexisting, and the polarization is serious. Therefore, comprehensively promoting the rural revitalization strategy, adhering to the integrated development of urban and rural areas, and enhancing inter-regional collaborative governance are powerful measures to promote the joint progress of new urbanization and high-quality agricultural development.
