广西北部湾经济区人口与经济空间分布关系分析

摘要：运用区域重心、地理集中指数等分析方法，对广西北部湾经济区1998—2010年人口与经济空间分布关系进行研究，并结合不一致指数对经济区发展类型进行了划分。研究结果显示：北部湾经济区人口重心位于几何中心的东南方向，经济重心则由位于几何中心的东南方向往西南方向转移，并呈现南北波动的格局，人口重心的移动远远慢于经济重心的移动；研究时段内北部湾经济区人口与经济地理集中度沿着南宁-北海一带分布；根据这两个地理集中指数将北部湾经济区各县（市）分为三种类型：人口集聚滞后于经济集聚、人口集聚与经济集聚协调发展和人口集聚超前于经济集聚。

y on the Relationship Between Population and Economic Spatial Distribt in Guangxi Beibu Gulf Economic Zone

Thanks to the help of population and GDP data of Guangxi Beibu Gulf Economic Zone from 1998 to 2008, based on the methods of regional gravity center and geographic concentration in- dex, the coupling characteristics of the population and the economy of Guangxi Beibu Gulf Economic Zone are analyzed, and the economic zone has been divided into three types by inconsistent index. Con- clusions are found as follows：（1） The population gravity center of Beibu Gulf Economic Zone is loca- ted in the southeast direction. The economic gravity center transfered to the southwest direction from the southeast at the geometric center, and presented a north-south fluctuation pattern.The mobile of the population gravity center is much slower than the economic gravity center. （2） The degree of geog- raphy concentration of population and economy distributed along the Nanning-Beihai area in the study period.（3） According to inconsistent index, the Beibu Gulf Economic Zone can be divided into three types： population concentration lags behind economic concentration~ population concentration is har- monized with economic concentration; population concentration advances before economic concentra- tion.
