新型城镇化与美丽中国建设协调度研究OA

The new type of urbanization and the construction of"Beautiful China"are two major development strategies in China,with critical importance to advancing regional green sustainability.By combining the coupling coordination degree model and spatial data analysis,the spatiotemporal patterns and influencing factors of the coupling and coordination between these two systems were investigated using data from 2013 to 2023 for Jiangsu Province.The results indicated that during the research period,the comprehensive index of new urbanization in Jiangsu increased significantly from 0.101 to 0.900,whereas that of the construction of"Beautiful China"fluctuated and rose from 0.421 to 0.595.The degree of coupling coordination improved consistently from 0.319(basic incoordination)in 2013 to 0.829(good coordination)in 2023.The relative development status shifted from the lagging state of new urbanization to the lagging state in the construction of"Beautiful China".Factors such as rural domestic sewage treatment and comprehensive utilization rate,among others,significantly influenced the coordination degree,development degree,and coordinated development degree of the two systems.In particular,the rural domestic sewage treatment and the comprehensive utilization rate had the greatest impacts,with individual contribution rates of 26.9%,66.7%,and 69.5%to the degree of coordination,development degree,and degree of coordinated development,respectively.The coupling coordination development status of various prefecture-level cities indicated significant spatial heterogeneity,with the spatial pattern of southern region>central region>northern region;moreover,as the research progressed,the coupled and coordinated development status of each prefecture-level city gradually improved.By 2023,Nanjing and Wuxi had reached the good coordination category.Compared with that in 2013,the overall regional coordination level improved markedly.Moving forward,the development of new-type urbanization in Jiangsu Province must prioritize ecology,enhance regional ecological carrying capacity,and then accelerate urbanization in various dimensions,including spatial and population development,thereby achieving the strategic goal of building a high-quality"Beautiful China"construction.
