摘要
产业集群中的企业技术创新行为,由于受产业集群特性的影响,表现出与一般企业技术创新明显不同的特征,其中较重要的一点是产品差异化程度和溢出效应对企业技术创新具有较明显的影响。本文以D’Aspremont与Jac-quem inde的技术研发博弈模型为基础,采用斯潘斯(Spence)和迪克塞特(D ixit)的有产品差异化的反需求函数,建立起集群企业技术创新的动态博弈模型,具体分析了集群企业的产品差异化程度、技术溢出效应对集群企业研发投资的影响,并从中得出一些有价值的结论。
As a result of the influences of industrial cluster, the technological innovation behaviors of enterprises are displayed with many different characteristics compared with the common enterprises. Furthermore, the most important characteristic is that the product differentiation and spillover effect has exerted great influence on technological innovation. On the basis of the R＆D gambling model of D＇Aspremont and Jacqueminde, the article, using the product differentiation counter-demand func- tion of Spang Si and Dick Sert has established a dynamic gambling model for the technological innovation of the enterprises in industrial cluster. Moreover, it has specifically analyzed the influences of the product differentiation and the spillover effect to the cluster enterprise＇s R＆D investment, and draws some valuable conelusions.
