| 摘 要： | 通过研究区域内各个城市之间的引力关系，能够探索城市之间的经济关系，这是合理划分城市圈内城市组团，实现城市组团协同发展的基础。基于城市竞争力和矢量的城市引力模型，通过加入心理距离相关理论对模型进行了改善，并以成都城市圈为例，阐述成都城市圈引力格局现状及经济联系。结果表明:通过改进后的城市引力模型计算的引力结果，反映出城市相对引力现状基本符合客观事实；成都城市圈明显呈现出“一家独大”的经济格局，成都市的城市竞争力和引力远远超出平均水平，整个城市的经济联系过于分散，区域内各城市发展不均衡，有待未来改善。

| Abstract: | By studying the gravity relationships among cities within the region，the economic relationships among cities can beexplored，which is the basis for reasonably dividing the urban groups within the city circle and achieving the coordinateddevelopment. Based on the theory of urban gravity model，this paper introduces the theory of psychological distance and improvesthe urban gravity model based on the urban competitiveness and vector-based gravity model. Taking Chengdu city circle as anexample，this paper expounds the current situation and economic connection of Chengdu city cycle’s gravity pattern. The resultsshow that the improved gravity model can objectively reflect the current conditions of relative gravity among cities. The city circle ofChengdu clearly presents the economic pattern of "overdominance". The urban competitiveness and gravity of Chengdu are farbeyond the average level. The economic connection of the whole city is too scattered and the regional development is not balanced，which need to be improved in the future development. |
