摘　　要：运用经济重心模型计算东北三省及各省份经济重心和几何中心,从经济重心与几何中心的空间关系、经济重心在经线和纬线方向的移动距离等方面分析东北三省及各省份经济重心变化规律,反映东北三省经济差异的时空演化特征,结果显示:东北三省的经济重心位于几何中心西南方的四平市内,经济重心在经线方向的移动距离大于纬线方向,说明东北三省南北向经济差异变化较大;国家实施振兴东北老工业基地战略以来,经济重心持续南移,后趋于稳定,说明区域经济不均衡性在扩大;3个省份内部经济重心偏离几何中心的距离和年际移动距离小于东北三省总的偏离距离和年际移动距离,说明3个省份间的经济差异是造成经济重心移动的主要原因。Economic gravity center and geometric center of Northeast China were calculated by economic gravity moaei;men the space-time evolution feature of economic gravity center was analyzed from the relationship between economic gravity center and geometric center,moving track in latitude and longitude was got, which could reflect the spatial and temporal character of re gional economic differences. The results are as follows： 1） Economic gravity center is located in Siping City, which is in the southwest of geometric center; the distance of economic gravity center moving is longer in latitude than longitude which reflects that the economic difference changes greater in north to south direction. 2） Since the Chinese state implements the Strategy of Rcvitalizing Northeast China and Other Old Industrial Base（from 1994 to 2011） ,economic gravity center moves southward con tinuallv,which reflects that regional economic imbalance becomes larger. 3） The distance between economic gravity center and geometric center in Northeast China is longer than in each of the 3 provinces,and it＇s all the same with the distance of economic gravity center moving,which reflects that the economic differences among three provinces is a major cause of economic gravity center moving.
