中文摘要：

运用空间基尼系数、赫芬达尔指数、EG指数、区位商对长三角知识密集型服务业的空间集聚状况进行量化测度,通过全局自相关分析判定影响长三角知识密集型服务业空间集聚的因素。从城市层面来看,上海作为长三角的龙头城市,其知识密集型服务业的空间集聚特征最为显著;从知识密集型服务业本身来看,除整体上表现出明显的空间集聚发展特征之外,金融业空间集聚程度最高,并且政府行为和城市（区域）开放度对长三角知识密集型服务业空间集聚发展影响最为显著。

英文摘要：

Through using the Gini coefficient, Herfindahl index, EG index, location quotient, the paper analyzes the spatial agglom- eration status of knowledge intensive business service （KIBS） in Yangtze River Delta. And by the analysis of Global autocorrelation, it determines the main factors that affects the development of spatial agglomeration of KIBS in Yangtze River Delta. From the city level, as the leading city of Yangtze River Delta, spatial agglomeration characteristics of shanghai KIBS is the most significant. From the perspec- tive of KIBS, it shows significant spatial agglomeration characteristics in the whole industry. At the same time, financial industry has the highest spatial agglomeration in the four sub-sectors of KIBS; government action and city （regional） openness are the most signifi- cant factors affecting the space agglomeration of KIBS of the Yangtze River Delta.
