摘　　要：为深入研究成渝城市群内各城市间的经济联系状况以及演化过程,采用主成分分析法以及修正后的引力模型,对成渝城市群内36个城市的城市质量、经济联系进行计算和分析,研究成渝城市群2009-2019年城市经济联系的空间格局及其演化。结果表明:(1)成渝城市群内各城市的质量总体上不断提高,在空间上呈现出不平衡状态,西北部城市质量较高,东部城市质量较低;(2)重庆都市圈和成都都市圈的经济联系量大,区域内呈现出经济发展不均衡分布的空间格局;(3)以成都、重庆为双核心的成渝城市群的网络化进一步发展完善,经济联系和结构复杂程度增加,但各城市之间经济联系量仍较低,2个核心对外的辐射带动作用较弱。在此基础上,提出促进成渝地区经济协调发展的建议。To study in depth the status and evolution process of economic ties among cities in Chengdu-Chongqing city groups,the principal component analysis method and the revised gravity model are adopted to calculate and analyze the urban quality and economic ties among 36 cities and study the spatial pattern and evolution of urban economic ties from 2009 to 2019.The results show that the overall quality of cities in Chengdu-Chongqing city groups are constantly improving;the spatial unbalance is embodied by the higher quality of northwest cities and lower quality of east cities;there are a large number of economic ties between Chongqing city group and Chengdu city group,showing a spatial pattern of unbalanced economic development in the region;with Chengdu and Chongqing as its dual cores,the network of Chengdu-Chongqing city groups has been further developed and improved;the density of economic ties and the complexity of its structure have both increased;however,the gravity value of economic ties among cities in the city groups is still quite low,and the external radiation driving effect of the two cores is relatively weak.Therefore,some suggestions on this basis are put forward to promote the coordinated economy development of Chengdu-Chongqing Region.
