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。

Abstract:The oLS ignores its spatial heterogeneity and locality when testing international R&D knowledge spillo-vers induced by fbreign direet investment(FDI).The spatial dependeney was iUustrated with the spatial knowledgespillovers indLlced by FDI as the starting point.Using a panel data of 29 provinoes in China from 2000-2010,thepaper eonstrueted spatial Durbin model to quantify the international R&D spiUovers effects to TFP based on the C-H model,considering the spatial property of taelt knowledge was omitted from C-H model.The spillover impactswere partied to illustrate the spatial lagging nature as move from low-order to higher-order eontiguity matrix.Theempirical resuh showed that international R&D knOWledge spillovers had a prominent positive eflfect on the progressof Chinese TFP,and the effect of knowledge spillovers on the regional innovation increased firstly and descend laterbecause 0f the spatial locality.

作为外商直接投资的主要流入国,我国当前正处于经济转型的重要时期,外商直接投资(ForeignDireet Investment,FDI)一方面通过知识溢出效应促进了我国的产业结构升级和经济结构调整,提升了产品国际竞争力,另一方面这种溢出效应又放大了我国对外资的依赖性以及全球性经济危机对我国经济稳定性的威胁,因而加大了国家的经济运行风险。因此,构建合理、有效的国际R&D知识溢出的分析框架,实证研究国际R&D对我国区域创新的空间知识溢出效应具有重要的价值和实际意义。
Romer最早将知识作为生产要素纳入生产函数,将创新产出作为创新投入的函数,以生产企业作为研究对象,构建了知识溢出的内生增长模型。……
