新型城镇化与绿色低碳循环发展的耦合协调及时空演化——以安徽省为例

The Coupling Coordination and Spatiotemporal Evolution of New Urbanization and Green and Low-Carbon Circular Development-A Case Study of Anhui Province

基于2011—2021年安徽省面板数据,本文构建新型城镇化和绿色低碳循环发展指标体系,利用熵值法测度了新型城镇化水平和绿色低碳循环发展水平,并通过耦合协调模型和空间自相关法,研究安徽省两系统耦合协调度的时空格局和空间聚集性。研究表明:(1)安徽省新型城镇化和绿色低碳循环发展综合水平逐年上升,但增速较慢。(2)各地级市新型城镇化与绿色低碳循环发展协调发展效应逐年增强,耦合协调度呈现明显的空间分异特征,合肥、芜湖、马鞍山三市的耦合协调水平明显高于其他地级市。(3)安徽省新型城镇化与绿色低碳循环发展的耦合协调度存在明显空间聚集性,高—高聚集区主要位于合肥、芜湖、马鞍山三市,低—低聚集区主要集中在阜阳市。

Based on the panel data of Anhui Province from 2011 to 2021,this paper constructs a new urbanization and green and low carbon circular development index system,measures the level of low carbon circular development and new urbanization by the entropy method,and studies the spatiotemporal pattern and spatial agglomeration of the coupling coordination degree of the two systems in Anhui Province through the coupling coordination model and spatial autocorrelation method.The results show that:(1)The comprehensive level of new urbanization and green and low carbon circular development in Anhui Province has increased year by year,but the growth rate is slow.(2)The coordinated development effect of new urbanization and green and low carbon circular development in prefecture level cities has increased year by year,and the coupling coordination degree has shown obvious spatial differentiation characteristics,and the coupling coordination level of Hefei,Wuhu and Ma’anshan cities is significantly higher than that of other prefecture level cities.(3)There is obvious spatial aggregation in the coupling coordination degree of new urbanization and green and low carbon circular development in Anhui Province,with high high aggregation mainly located in Hefei,Wuhu and Ma’anshan,and low low aggregation area mainly concentrated in Fuyang City.
