近60年来新疆经济重心转移的三次产业分解分析

本文利用区域重心的概念和模型,计算出新疆1949年～2009年经济（GDP）重心和三次产业重心,同时利用GIS技术将重心变化制作成图,得到建国以来新疆经济（GDP）重心和三次产业重心的动态演变轨迹;在此基础上分析了新疆总体经济发展和三次产业发展的区域差异的动态变化及其关系。结果表明：新疆经济（GDP）重心和三次产业的经济重心不仅存在很大的偏离,而且移动的方向和距离也存在较悬殊的差别;新疆经济（GDP）重心缓慢地向东北移动,区域经济差异总体上扩大了,造成区域经济差异的主要原因是第二、第三产业发展的区域差异。

The Decomposition Analysis of Economy Gravity Center in the View of Industry Gravity Center of Xinjiang in Recent 60 Years

Taking the conception and model of the regional gravity center,this paper calculates the GDP and Industry gravity center of Xinjiang province from 1949 to 2009,and then figures out the dynamic evolvements of these gravity centers.On the basis of the results,it analyses the dynamic evolvement and the relationship of the economy and industry regional differences,and from the analysis a conclusion can be drawn： the deviation between GDP gravity center and Industry gravity center is great,and moving direction and distance are with disparate difference as well;the economy（GDP） gravity center has a tendency of moving northwest of Xinjiang,in general,the regional economic differences is expanded,and this phenomenon is mainly caused by the factor of the secondary and the tertiary industry regional differences.
