摘　　要：山西省作为我国重要的能源化工基地,分析其县域经济发展差异,对促进区域经济协调发展有重大的意义。该文以山西省县域为研究对象,选取反映县域经济差异的15个指标,以2001～2007年份为研究时间截面,采用主成分聚类分析与GIS相结合的方法,对县域经济发展差异进行分析。结果表明:山西省107个县域单元可以分为五类:发达型、较发达型、中等型、落后型、较落后型;2001年至2007年山西省县域经济有了较快的发展,经济差异在逐步缩小。在研究截面里,全省多年人均GDP也有较大的增长趋势,贫富差异缩小。County economy disparity is a critical problem in coordinating regional economic development. Based on the investigation on economy of the 107 counties （cities） of Shanxi Province, this paper analyzed the county econo- my disparity using an approach combining GIS with principal component and cluster analysis. 15 indicators were se- lected to reflect economy disparity. The result showed that： 1 ） 107 counties （cities） of Shanxi province can be di- vided into five categories, i. e. , advanced developed, less advanced developed, middle developed, backward de- veloped, and more backward developed counties; 2） county-level economic situation in Shanxi province has devel- oped significantly from 2001 to 2007. Especially, the regional economic differences were narrowed gradually; 3 ） Per capita GDP in Shanxi also showed a growing trend from 2001 to 2007 and the gap of county - level economy dis- parity shrank gradually.
