中文摘要：
采集呼包鄂榆经济区内38个旗县区2001、2005和2009年的数据，利用SPSS、AGCGIS、ESDA软件进行主成分分析、空间相关分析和可视化处理，研究县域经济的时间变化、空间变化、空间相关关系。结果表明：县域经济差异的年际变化曲线相对稳定，各县经济差异变化没有明显起伏；四种类型县域经济变化相对稳定，局部有明显变化；大城市的极化作用相对明显，而扩散作用明显不强；县域经济水平类型数量结构从“水桶型”向“橄榄球型”演变；县域经济水平的分布呈中心高、四周低的分异状态，经济发达县和高收入县主要分布在鄂尔多斯中部、呼和浩特城区、包头城区，低收入县主要分布在榆林市南部，集中分布；县域经济水平空间结构呈典型的“三核”形态，呼和浩特市、包头市、东胜区构成区域经济发展的“中心”，但对区域经济的辐射带动作用不足；县域经济水平具有为明显的空间集聚性，即高值集聚、低值集聚的格局，高值集聚在鄂尔多斯中部，低值集聚在榆林市南部；热点区域主要是东胜区，盲点区域主要是榆林市南部8个旗区。
英文摘要：
Hohhot-Baotou-Erdos-Yulin region is one of the fastest economic development regions of western China in recent years. The paper collection these data of 12 indicators of 38 counties in this region from 2001 to 2009, use SPSS, AGCGIs, ESDA software to do principal component analysis, space analysis, visualization, study the temporal, spatial variation and the spatial correlation of the county economy. The results show that ： the inter-annual variation curve of the economic differences among counties is the relatively stable：, there is no obvious ups and downs. The changes of four county economy types is relatively stable, there is obvious change in local counties. Polarization effects in large cities are relatively Significantly, while the diffusion effects is obviously not strong. The number structure of county economic level type evolves from the ＂bucket-type＂ to ＂football-type＂. The distribution of county economy Level was that the high economic level counties was in center, surrounded by low economic level counties, economic developed counties and high-income counties are mainly located in the Ordos central, Hohhot City and Baotou City District, low-income counties are mainly located in the south of Yulin City. County economic level spatial structure was typical ＂Triple-core＂ morphology, Hohhot City, Baotou City, Dongsheng District constitute the ＂center＂ of regional economic development, but they are inadequate leading role on the regional economy. There are the obvious spatial clustering with the county economic level, this means that the high-score clustering and low- score concentration, the high-score clustering in the Erdos Central, low gather in the south of Yulin City. There are the obvious the hot zone and the blind spot area of the county economic level, the hot zone is in Dongsheng District, the blind area is in the south of Yulin City.
