成渝经济区主要城市间经济联系方向性研究

Research on the Economic Contact Directions of Major Cities in Chengdu-Chongqing Economic Zone

构建了综合评价城市竞争力指标体系,对成渝经济区16个地级城市的竞争力进行主成分分析。建立了城市经济联系模型计算城市之间的联系强度,模拟城市发展趋势和方向,综合评价成渝经济区各城市对外联系强度,并运用ARCGIS对矩阵数列进行可视化处理,明确城市经济发展的实体空间方向。结果表明,成都和重庆是成渝经济区的中心城市,这2个城市的联系强度最高;以成都为核心,以德阳、绵阳为方向的经济联系趋向性最强,其次是眉山、乐山、资阳;以重庆为中心的城市经济关联趋向性不明显。成渝经济区经济联系的地理空间指向性明显,城市经济联系的趋向性很大程度上受交通和区位影响。

An comprehensive evaluation index system for city competitiveness was constructed,and a principal component analysis was carried out on the competitiveness of 16 cities in Chengdu-Chongqing Economic Zone.The city economic contact model was established to calculate the relations among cities,to simulate the development trend and direction of cities and comprehensively evaluate the external economic links of each city,matrix series were visualized treated with ARCGIS so as to make clear the spatial direction of city economic development.As indicated by the results,Chengdu and Chongqing were two closely related central cities;With Chengdu as the center,the economic contact trend was the strongest in the direction of Deyang and Mianyang,then followed by Meishan,Leshan and Ziyang;the economic contact trend with Chongqing as the center was not obvious.The direction of economic contact was effected obviously by geo-spatial directivity in chengdu-chongqing Economic Zone.
