摘　　要：通过空间自相关性指标量测分析发现,中国创新活动呈区域化状态,有明显的空间集群现象,并且主要集中在城市化水平较高的环渤海湾和长三角城市群。基于截面数据所建立的空间计量经济学模型发现:城市化、研发投入和市场化均有助于知识的空间溢出;空间误差模型(SEM)中城市化变量的估计非常显著,明显高于普通最小二乘估计(OLS)的结果;并且参数λ显著为正,相邻地区的创新产出对本地区创新产出有正向影响,存在知识在空间上的溢出现象。By using spatial autocorrelation test, it is revealed that the innovation activities in China are highly regional- ized and spatial clustered, which are centralized along the urbanized Bohai Rim and Yangzta Delta region. The paper further constructs a spatial econometric model to measure the spillover effect. The results suggest that： urbanization, R＆D, and marketization can promote spatial knowledge spillover; the estimation of urbanization by SEM is more significant than that of OLS ; perimeter in the model is significantly positive, which means the innovation of neighboring areas can strengthen the local innovation activities and there is spatial knowledge spillover phenomenon.
