运用空间变异函数和空间自相关分析模型，以地均GDP为指标，重点从省域和县域尺度分析2000年以来中国经济的时空分异特征。结果表明：①中国地均GDP由103万元/平方公里增加到418万元/平方公里，北方省份的经济增长速度快于南方，东部地区和西部地区的经济增长速度较快；②大多数县域地均GDP低于全国平均水平，“东高西低”阶梯式递减的规律明显，经济发展热点区呈现出“北移西进”的态势；③中国县域经济表现出较强的空间自组织性，热点区域在环渤海地区、长三角和珠三角地区积聚，东南-西北方向地均GDP的空间差异最大。
Comprehensively using the methods of ESDA，Moran’s I，Getis-Ord General G and spatial variogram，this article describes and analyzes the spatial characteristics of per km2GDP in China during 2000-2010.（1）per km2GDP increases from 103×104yuan/km2 in 2000 to 418×104yuan/km2 in 2010. Rapid economic growth of China experienced a spatial shift from coastal regions to inland regions，and economic gravity center moved northward and westward.（2）Considering the overall spatial framework，per km2GDP at county level in China shows a significantly trend of spatial natural correlation. The hotspot regions expand obviously，with circular space structure centered on the area along Bohai Rim，the Yangtze River Delta and the Zhujiang Delta.（3）The spatial self-organized characteristicsof per km2GDP has become stronger and stronger. The homogeneousness of per km2GDP in the direction of northeast-southwest is typical for its relatively small spatial difference.
