摘　　要：通过建立城市经济综合质量指标体系、OD成本距离矩阵并考虑产业结构差异修正传统引力模型,结合社会网络分析法,以2010年、2015年、2020年为时间节点,研究成渝双城经济圈内36个行政单元的经济联系网络格局演变特征及趋势。结果表明:(1)2010—2020年成渝双城经济圈城市经济联系强度和网络密度水平均较低,但有缓慢上升趋势,城市经济联系网络总体呈两极化、密集化、复杂化趋势。(2)网络中心势水平总体较高,但有缓慢下降趋势,成都和重庆中心城区中心性水平高,点入度高于点出度,城市间相互作用较明显,对核心城市的依赖程度略微下降。(3)凝聚子群构成城市较稳定且地域邻近性强,成都、重庆中心城区为核心的第一子群聚集性显著,是资源互通和产业交流中心。(4)成都和重庆中心城区为两大核心区,过渡区城市核心程度波动上升,大部分边缘区城市边缘化程度小幅降低,核心-边缘结构明显。This paper modifies the traditional gravity model by establishing the comprehensive quality index system of urban economy,considering the difference of industrial structure,and combining with the social network analysis method,taking 2010,2015 and 2020 as time nodes,studying the evolutionary characteristics and trends of the economic connection network pattern of 36 administrative units in the economic circle.The results show that:(1)The level of urban economic connection intensity and network density in the economic circle in the years of 2010,2015 and 2020 is low,but there is a slow upward trend,and the urban economic connection network shows a trend of being more bipolarization,intensification and complexity.(2)The network centrality in Chengdu and Chongqing is generally at a high level,with a slow downward trend.It shows an evident interaction among cities,and the degree of dependence on core cities is slightly decreased.(3)The agglomeration subgroup remains relatively stable with strong regional proximity.Chengdu and Chongqing central areas,as the core district of the first subgroup,which has a significant spatial aggregation,and is the center of resource interchange and industrial exchange.(4)Chengdu and Chongqing are the two core districts.In the transition area,the degree of urban core fluctuates,while the marginal area decreases slightly,and the core-periphery structure becomes more obvious.
