基于经济协同、设施互联互通、创新协同等7个维度构建成渝地区双城经济圈高质量一体化评价指标体系,并用熵权法测度2010-2020年发展水平,进而利用社会网络分析、Dagum基尼系数等识别内部各城市和各区域的时空特征,采用QAP回归分析剖析各维度对整体高质量一体化发展的内部驱动作用与特点.研究表明:①成渝地区双城经济圈内部城市高质量一体化发展多数为低和中低水平,高质量一体化空间关联网络结构脆弱,城市关联不紧密,核心边缘区总体保持"六强矗立"分布,各城市在网络中拥有不同的作用和地位.②成渝地区双城经济圈内部各区域高质量一体化水平从高到低依次为重庆、成都平原、川南、川东北,高质量一体化发展的空间差异不断缩小且主要来自区域间差异.③成渝地区双城经济圈整体高质量一体化及各分维度发展水平逐渐提升但发展水平均较低,除生态协同,其余因素均对高质量一体化发展具有显著的正向驱动作用.
High-quality integration level and spatio-temporal characteristics of the Chengdu-Chongqing Twin-City Economic Circle
An evaluation index system for high-quality integration of the Chengdu-Chongqing Twin-City Economic Circle was constructed based on seven dimensions including economic synergy,infrastructure interconnection,innovation synergy,etc,and the de-velopment level from 2010 to 2020 was measured by using the entropy method.Then,social network analysis and Dagum Gini coefficient were used to identify the spatiotemporal characteristics of each city and region in the interior,and QAP regression analysis was used to analyze the internal driving effect and characteristics of each dimension on the overall high-quality integration development.The results showed that:① The majority of cities with low and medium-low levels of high-quality integration development were located in the Chengdu-Chongqing Twin-City Economic Circle,the structure of the high-quality integration spatial linkage network was fragile,the cities were not closely linked,and the core and peripheral zones generally maintained the distribution of the"top six",with different roles and statuses for each city in the network.②The level of high-quality integration among the regions within the Chengdu-Chongqing Twin-City Economic Circle was,in descending order,Chongqing,Chengdu Plain,Southern Sichuan,and Northeastern Si-chuan,and the spatial differences in high-quality integration development were shrinking and mainly came from inter-regional differ-ences.③The overall high-quality integration of the Chengdu-Chongqing Twin-City Economic Circle and the development level of each sub-dimension had gradually increased but the development level was low,and except for the ecological synergy,all the other fac-tors had positively driven the high-quality integration development.
