A RESEACH ON THE ECONOMIC CENTRE EVOLUTION AND REGIONAL DEVELOPMENT EQUILIBRIUM OF NORTHEAST CHINA
基于GIS和重心模型，研究了1989年以来东北地区经济中心的空间偏移和区域发展均衡性，发现经济中心呈东北-西南往复移动且区域发展极化严重。
Based on GIS,this paper do some research on the regional development equilibrium of Northeast China since 1989.Firstly,the regional barycenter model is introduced to take a visible measurement over the time-spatial deviation of the economic centre of the Northeast China compared with its geometric centre.Combined with the related statistics indicators,we introduce the relative development ratio to systematically analyze the time-spatial characteristic of the regional development balance of Northeast China.The conclusions are drawn as follows:There is obvious spatial deviation of the economic centre in Northeast China;the economic centre moves from northeast to southwest,to northeast,and then back to southwest again;The regional development polarizes severely.
