甘肃省人口与社会经济重心的动态演变及其对比分析

Comparative Analysis of the Dynamic Evolvement Procedure of Population and Economy in Gansu Province

以人口分布与经济发展的相互作用关系为主线,以甘肃省86个县(市)为研究的区划单元,结合重心模型对近10年来甘肃省人口、经济的空间分布的动态演变过程做综合的比较分析。研究结果表明甘肃省经济重心始终位于人口重心的西北方向,反映了甘肃省经济发展水平与人口分布之间的不平衡性。1994—2004年人口重心、GDP重心以及三大产业的重心总体都呈现向西北方向移动的趋势,但经济重心的迁移幅度远大于人口重心,经济重心和人口重心的偏离距离在不断拉大,全省经济发展与人口分布的不平衡在加剧。

Taking the interaction between population distribution and economic development as the main thread and 86 towns of Gansu province as the research object , using the Gravity Model to do a com- prehensive comparative analysis of the dynamic evolvement procedure of population and economic spatial distribution of Gansu province over the past some 10 years. The results show that the economic center of gravity is always located in the northwest of the gravity of the population, that reflecting the imbalance between economic development and population distribution in Gansu province. From 1994 to 2004, the gravity of population,the GDP and three industrials have a tendency of moving northwest. However, the rate of migration of the economic center of gravity is far greater than the grivity of the population . Showing that the imbalance between economic development and population distribution is intensifying.
