| 摘 要： | 分析经济区内城市间经济联系不仅有利于引导城市的空间发展,而且有利于空间经济的合理组织。以皖江城市带为例,引入克鲁格曼指数、建成区面积、人口素质权重系数等指标修正了以往的引力模型,并利用城市间的日发车班次数据对修正模型进行了检验。在此基础上,利用修正模型确定了各城市的主要对外联系方向及联系强度,采用断裂点公式计算了中心城市的吸引范围。结果表明:①皖江城市带内各城市对外经济联系强度差异较大;②各城市的主要联系方向呈现中心城市指向性和地域相邻指向性特征;③合肥和芜湖为皖江城市带的两个经济中心城市,它们的对外吸引范围较为狭小。 |
| 关 键 词： | 经济联系 引力模型 辐射范围 皖江城市带 |

| Abstract: | Through the analysis of the economic links between cities,it may supply the development orientation to the city and is conducive to the reasonable organization of economic space.The paper revises the city gravity model by using the index of Krugman,the area of built-up areas and the coefficient of the population quality.Empirical research is made by utilizing the frequency data of the bus departure in a day.Based on the revised gravity model,we have analyzed the main directions and intensities of urban econ... |
