中文摘要：

以长三角城市群为研究案例区,运用ESDA探索性空间数据分析法,通过Arc GIS/Geo Da软件对长三角城市群R＆D投入相关数据进行分析,得出其空间分异及演化特征。主要结论包括：1长三角城市群研发投入要素城市间差异化的整体变化呈逐渐缩小的趋势;2总体来看,长三角研发投入要素中的创新人员投入出现相似水平城市集聚显著特征,而研发经费投入出现显著的极化现象;3具体来看,研发人员投入呈现由以上海为核心的两翼延伸的＂V＂字形向环杭州湾南移的发展态势,呈现南高北低的分布现状,而研发经费投入呈现以上海为绝对高值极化中心,杭州、苏州、南京、无锡为次级极化中心的多极鼎立的空间指向。

英文摘要：

The concentration ratio and continuity of RD input is of great importance to regional innovation. This paper set Yangtze River Delta city group as study area, applied ESDA analytical method, in virtue of Arcgis/Geoda software in analyzing RD input data. Expecting that the research result would boost regional integration and regional coordination of the angtze River Delta city group area. The main conclusions are： 1）Rd inputs between cities is narrowing.2） overall,spatial characteristic of the RD Professional Innovator appeared distinguishing feature of regional aggregation, while the RD expenditure appears polarization characteristic. 3）Concrete analysis, the aggregation tendency of RD Professional Innovator is lower from north to south, the hot spot transferred to the southern cities; Shanghai is the polarization core of RD expenditure, secondary polarization center are Hangzhou, Suzhou, Nanjing and Wuxi.
