| 摘 要： | 基于空间经济学"城市引力"模型,构建了经济质量指标体系,运用主成分分析法提取公因子测算了成渝城市群各城市的经济质量,利用时间和货币距离计算了各城市间的经济距离,并综合计算了城市间的经济引力.研究结果表明:成渝城市群各城市与成都、重庆两市间的经济引力仍存在较大差异;成渝城市群内部仍存在发展不均衡现象;城市间的地理距离与其经济距离并不存在必然的相关性.基于此,有必要进一步加强成渝城市群各城市经济质量建设,完善成渝城市群交通路网结构,形成成渝城市协同发展的体制机制,逐步推进成渝城市群经济的一体化发展.

| Abstract: | This paper attempts to construct a model of an urban gravity which based on structure economic quality index system.It estimates the economic quality of each city by using principal component analysis,calculates the economic distance of the Chengdu-Chongqing urban agglomeration with the distance of time and money.Results show that each city in this urban agglomeration still have considerable differences between Chengdu and Chongqing's economic gravity,and the development of each city in there is different.There are no inevitable connections between the geographic distance and the economic distance.Therefore,it is necessary to further strengthen the construction and to improve the transportation network structure of Chengdu-Chongqing urban agglomeration for promoting the development of economic integration in the Chengdu-Chongqing urban agglomeration gradually. |
