中文摘要：

经济活动最重要的地理特征之一是产业集聚,而服务业比制造业更具空间集聚效应.运用Theil系数、空间基尼系数、赫芬达尔系数以及空间自相关方法分析长三角地区服务业及其典型行业集聚特征和空间格局.结果表明：2003-2010年长三角服务业空间存在显著差异但在逐步缩小,不同类型地区对差异有不同的贡献率;区域集聚程度由大到小为房地产业,流通业,批发零售业,住宿餐饮业,金融业,呈现倒＂U＂型变化;行业集中度由大到小为房地产业,流通业,住宿餐饮业,批发零售业,金融业,表现为波动性上升趋势;服务业表现出空间正相关性,高值集聚显著主要集中在上海地区,集聚水平低的地区主要在南部区.并基于测度结果提出了一些优化调控建议.

The most important geographical features of economic activity is industrial concentration ,and service industry has more agglomeration effect than manufacturing .Mainly based on using Theil‐coeffi‐cient ,Spatial Gini‐coefficient ,Herfindahl coefficient ,Spatial autocorrelation and other methods and indi‐cators ,in this article the model has been measuredof locality distribution ,the industrial characteristics ,the specialized rate of service industry in each city of this region from 2003 to 2011 .The analysis results indi‐cate that the services space of Yangtze river delta exists significant difference but gradually narrowed ,and different types of regional differences have different contribution rate;in regional cluster ,real estate in‐dustry〉circulation〉 wholesale and retail〉 accommodation catering 〉 finance ,present the inverted “U”type change;in industry concentration , real estate industry 〉 circulation 〉 accommodation catering 〉wholesale and retail〉finance ,characterized by volatility rising trend;services space showed positive corre‐lation ,w hile high value agglomeration are mainly concentrated in Shanghai area ,low level of agglomera‐tion areas are mainly in the southern area .Finally ,some optimization adjustment suggestion are put for‐ward .
