| 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。 |

| Abstract: |
| 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. |
