摘　　要：对于FDI引致的国际R&D知识溢出的研究,通常主要基于OLS方法构建的线性模型,忽视了知识溢出的空间时滞性和空间局限性。利用中国29个省(直辖市、自治区)2000—2010年的面板数据,以C-H模型为基础构建了国际R&D知识溢出对我国全要素生产率的影响模型。考虑到不可测度的隐性知识资本所具有的空间属性,将其作为遗漏变量,扩展为空间杜宾模型。将知识溢出效应按照空间邻接矩阵的阶数进行分解,用于分析知识溢出的空间滞后性。分析结果表明国际R&D知识溢出对我国的全要素生产率具有显著正效应,但由于空间局限性的作用,知识累积的溢出效果对区域创新的作用呈现先增大后减少的空间衰减趋势。The OLS ignores its spatial heterogeneity and locality when testing international R＆D knowledge spillo- vers induced by foreign direct investment（FDI）. The spatial dependency was illustrated with the spatial knowledge spillovers induced by FDI as the starting point. Using a panel data of 29 provinces in China from 2000--2010, the paper constructed spatial Durbin model to quantify the international R＆D spillovers effects to TFP based on the C- H model, considering the spatial property of tacit knowledge was omitted from C-H model. The spillover impacts were partied to illustrate the spatial lagging nature as move from low-order to higher-order contiguity matrix. The empirical result showed that international R＆D knowledge spillovers had a prominent positive effect on the progress of Chinese TFP, and the effect of knowledge spillovers on the regional innovation increased firstly and descend later because of the spatial locality.
