摘　　要：从社会经济与地理特征两方面构建6个空间权重矩阵,以2003-2013年的创新投入产出数据为样本,研究长三角区域创新空间集聚。Moran指数显示区域创新有明显的正空间相关性,且相关程度在增强;实证表明长三角区域创新集聚拟合为个体随机效应的SEM模型更合适;空间权重矩阵的变化,在Moran指数、LM检验以及空间模型对长三角的区域创新集聚的判定方面并无本质影响,但在空间相关程度强弱方面有显著性影响。This paper constructs six spatial weight matrixes from the geographical features and social economic characteristics, respectively, samples the innovation input and output data from 2003 to 2011, and studyies the spatial dependence of technological in- novation of the Yangtze River Delta. The Moran＇s values show that the regional innovation activities in the Yangtze River Delta has a significant positive spatial correlation, and the degree of correlation is enhanced. Empirical results indicate that the SEM model with in- dividual random effects fitting Yangtze River Delta regional innovation agglomeration is more appropriate. With the change of the spatial weight matrix, there is no essential influence on the decision of the Moran index, the LM test and the spatial model of the Yangtze Riv- er Delta Regional Innovation Cluster, but there was a significant impact on the degree of spatial correlation.
