中文摘要：

主要采用有关统计年鉴中的就业人数数据，分别选用变异系数、空间基尼系数和区位商测算r长株潭城市群2003—2008年生产性服务业的空间分布差异程度和集聚程度。结果表明：就整个生产性服务业而言，空间分布较为分散，在全国的集聚程度也不高，但具有集聚发展的趋势；从不同城市看，长沙集聚程度最高，株洲和湘潭则相差甚远；从行业看，科学研究、技术服务和地质勘查业以及批发零售贸易业的集聚度较大，而金融业及交通运输、仓储和邮政业的集聚度很小，其它行业的集聚度居中；此外，信息传输、计算机服务和软件业的空间基尼系数连年下降。认为要使生产性服务业朝着更集聚的方向发展，应在空间分布和结构优化两个层面实行差异化的调控。

英文摘要：

Mainly adopting the number of employment coming from the relevant statistical yearbooks, the paper measured Variation-coefficient（ V ）, spatial Gini-coefficient（ G ）and Location Quotient（ Q ）in order to understand the spatial distribution difference and the agglomeration degree of producer service in Changsha- Zhuzhou-Xiangtan urban clusters from 2003 to 2008. The conclusion is： For total producer service, its spatial distribution was dispersive, its agglomeration degree in China also wasn＇t high, but it had agglomerative tendency. In different cities, the agglomeration degree of Changsha＇s producer service industry was the biggest, but those of Zhuzhou and Xiangtan were much smaller. As for every inner industry of producer service, the agglomeration degrees of Scientific Research, Technical Service and Geological Prospecting as well as Wholesale and Retail Trade were higher, while those of Transportation, Storage and Post Service industry, and Finance much lower. The others were at a medium place, as compared with the foregoing industries. In addition, the magnitude of spatial Gini-coefficient about Information Transmitting, Computer Services and Software industry dropped year after year. The authors consider that for promoting producer service agglomeration, different regulating and controlling measures on the aspects of spatial distribution and structural optimization should be adopted.
