摘要 运用知识生产函数和空间分析中的空间滞后模型、空间误差模型,对我国省域内产研地理接近所引起的内隐知识的专业化溢出、多样化溢出及Porter溢出和省域间技术溢出在区域创新中的作用进行了计量分析。结果,三种溢出作用随时间点的不同呈有规律的变化。总体而言,专业化和多样化溢出对区域创新存在正面影响,Porter溢出对区域创新存在负面影响。知识的省域间溢出对区域创新绩效的影响是通过空间滞后模型表现出来的,而且这种溢出仅发生在相邻省区之间,二阶滞后的省域间知识溢出不明显。 The paper utilizes special lag model, space error model in knowledge production function and special analysis to conduct the quantitative analysis for the function of professional spillover, diversified spillover and Porter spillover and provincial technology spillover of inner-hidden knowledge caused by production-research geography close in regional innovation. The result shows the function of three kinds of spillover changes regularly with the time changes. Generally speaking, professional and diversified spiUover makes a positive effect on regional innovation, Porter spiUover makes a negative effect on regional innovation. The effect of provincial spillover of knowledge for regional innovation performance is shown by spacial lag model, moreover, this kind of spillover only occurs in adjacent provinces and regions, the secondphase lag provincial knowledge spillover is nor obvious.
