摘　　要：利用至2009年的省级数据,与前人结论进行了对比,纠正了某些认识。①与我国几何中心相比,人口重心和经济重心均表现出不均衡性;②政策因素和由此导致的开放程度、开放时序的差别,是区域差异的最主要原因之一;③经济危机是经济重心产生剧烈跳动的主要原因;④广东省人口的快速增长是人口重心持续的西南向移动的真正原因,而经济重心的东南向移动是珠江三角洲和长江三角洲经济发展共同作用的结果;⑤人口重心和第一产业重心较为吻合,而与经济重心、第二产业重心、第三产业重心较为离散。From the latest data （2009） at the provincial level, the paper analyzes spatial-temporal change of regional difference and spatial pattern in China which take population gravity centers and economic gravity centers as examples, some of the conclusions can been drawn with different and even opposite viewpoints in contrast with previous research results. Compared with the geometric gravity centers, population gravity centers and economic gravity centers have shown imbalance since 1990. The policy factors, the following openness degree and the open timing differences have been the most important reasons of regional differences. The new regional policy brings the conversion of economic engine, so the role and the status of Pearl River Delta, Yangtze River Delta and other regions have changed, which could be as the main reason for changes of population gravity center and economic gravity center. Population gravity center, primary industry gravity Center and second industry gravity center will gradually move toward north and west. Economic crisis has been the main reason for a sharp jump of economic gravity centers, and the economic crisis in 1997 and 2007 caused a sharp jump respectively to the opposite orientation （north, west） against the overall trend. The rapid population growth of Guangdong Province has been one of the main reasons for continuing southwest move, and effect of economic development of the Pearl River Delta and the Yangtze River Delta together has arisen southeast move for economic gravity center. Population gravity centers are more consistent with the primary industry gravity centers than others.
