黄河流域城市群社会经济与生态环境耦合协调空间网络分析

Spatial Network Analysis of Coupling Coordination Between Social Economy and Eco-Environment in Yellow River Basin Urban Agglomerations

文章运用耦合协调度模型测度黄河流域7个城市群2006—2020年的社会经济与生态环境耦合协调水平,通过引力模型、社会网络分析及QAP方法研究耦合协调的空间网络结构特征及其影响因素。研究发现:(1)研究期内黄河流域城市群的社会经济与生态环境耦合协调度整体呈上升态势,呼包鄂榆、山东半岛城市群的耦合协调度较高,城市群内部高耦合协调度基本集中在省会城市。(2)稳步建设阶段的城市群耦合协调空间网络结构相较于引导培育阶段的城市群更为复杂。同时,各城市群内耦合协调空间联系具有明显的地域邻近指向和中心城市指向。(3)7个城市群整体网络密度较低,城市群内部空间联系较弱,城市群具有显著核心—边缘结构特征。(4)地理邻接、绿色创新一直是城市群耦合协调网络的重要驱动因素,而对外开放差异、交通设施差异却呈现抑制作用。

This paper measures the coupling coordination level of social economy and eco-environment in the Yellow River Basin's seven urban agglomerations from 2006 to 2020 by the coupling coordination degree model.It uses the methods of the modified gravity model,the social network analysis and the quadratic assignment procedure(QAP) to analyze the spatial network structure characteristics and influencing factors of coupling coordination between social economy and eco-environment.The findings are as follows:1) During the study period,the coupling and coordination degree of social economy and eco-environment in the Yellow River Basin urban agglomerations showed an overall upward trend.The coupling coordination degree of urban agglomerations in Hohhot-Baotou-Ordos-Yulin and Shandong Peninsula was relatively high.The high coupling coordination degree within the urban agglomerations is basically concentrated in the provincial capitals.2) The spatial network structure of coupling coordination of urban agglomerations in the steady construction stage is more complex than that in the guiding and cultivating stage.At the same time,the spatial connection of coupling coordination in each urban agglomeration has obvious geographical proximity and central city orientation.3) The overall network density of the seven urban agglomerations is low,and the spatial connection within the urban agglomeration is weak,the core-periphery structure of urban agglomeration is obvious.4) Geographical proximity and green innovation have always been important driving factors for the coupling and coordination network of urban agglomerations,while the differences in opening to the outside world and transportation facilities have an inhibitory effect.
