红三角经济圈人口与经济空间分布关系研究

在红三角经济圈1998-2008年人口和GDP数据支持下，应用区域重心和地理集中指数等方法，分析了红三角经济圈人口与经济的耦合特征，并结合耦合指数对经济区发展类型进行了划分。结果表明:红三角经济圈人口重心位于几何重心的北北西方向，经济重心位于几何重心的正西方向；人口和经济地理集中度均呈现西高东低格局；人口地理集中度和经济地理集中度高度相关；根据耦合指数，红三角经济圈可划分为经济超前型、协调发展型和经济滞后型三类区域。

Study on the Relationship Between Population and Economic Spatial Distribution in the Red-Triangle Economic Zone

The changes in the distribution of population and economics are very important in the regional studies.Based on the population and GDP data of Red-Triangle Economic Zone in 1998-2008 and the methods of regional center and geographic concentration index,the coupling characteristics of the population and the economy of Red-Triangle Economic Zone is analyzed.The economic zone has been divided into three types by coupling index.The following conclusions are obtaied:(1) the economic center is locateds in the west direction of the geometric center,and the population center is located in the SSW direction of the geometric center of Red-Triangle Economic Zone;(2) the degree of geographic concentration of population and economics in the west is higher than in the east;(3) the geographic concentration index is highly related between population and economics;(4) according to coupling index,the Red-Triangle Economic Zone can be divided into three types,the advance-economic type,the coordinate development type and the lag-economic type.
