人居环境与数字经济耦合协调的空间关系研究——以长江中游城市群及周边城市为例

Spatial Relationship of Coupling Coordination between Human Settlement Environment and Digital Economy:A Case Study of Urban Agglomeration and Surrounding Cities in the Middle Reaches of the Yangtze River

基于城市人居环境与数字经济的耦合协调发展机理,分别构建两者的评价指标体系,运用熵值法、耦合协调度和社会网络分析方法研究了长江中游城市群及周边城市的人居环境与数字经济耦合协调空间关系及其动力因素。研究发现:(1)城市人居环境与数字经济的耦合协调水平呈现空间不平衡特征,城市群内外部区域存在较大差异,省会城市的耦合协调水平较为突出;(2)与环鄱阳湖城市群相比,武汉都市圈和环长株潭城市群的耦合协调关联强度较高,对外辐射带动能力较强;(3)在城市群中心城市和周边城市的共同作用下,湖北和湖南两省的成员联系紧密,具有明显的凝聚性;(4)空间邻接关系、空间地理距离和产业结构是形成城市群内部空间关联网络的主要动力因素。研究揭示了人居环境与数字经济的动态耦合协调关系,为提升长江中游城市群人居环境数字化治理能力提供政策依据。

Based on the coupling and coordinated development mechanism of urban human settlements environment and digital economy,the evaluation index system of urban human settlements environment and digital economy was constructed in this paper.The spatial relationship and dynamic factors of coupling and coordination between human settlements environment and digital economy in urban agglomerations in the middle reaches of the Yangtze River and surrounding cities were studied by using entropy method,coupling coordination degree and social network analysis method.We found that:(1)The coupling and coordination level of urban human settlements environment and digital economy presented the characteristics of spatial imbalance.There existed great differences between the internal and external regions of urban agglomerations,and the coupling and coordination level of provincial capitals was more prominent;(2)Compared with the urban agglomeration around Poyang Lake,the coupling coordination correlation strength of Wuhan metropolitan area and the urban agglomeration around Changsha-Zhuzhou-Xiangtan was higher,and the external radiation driving ability was stronger;(3)Under the joint action of the central city and the surrounding cities of the urban agglomeration,the members of Hubei Province and Hunan Province were more connected and had obvious cohesion;(4)Spatial adjacency,spatial geographical distance and industrial structure were the main driving factors for the formation of the internal spatial correlation network of urban agglomerations.This study revealed the dynamic coupling and coordination relationship between human settlement environment and digital economy,which provided policy basis for improving the digital governance capacity of human settlement environment in the middle reaches of the Yangtze River urban agglomeration.
