产业集群内基于时间和距离的技术创新扩散模型研究

Technology Innovation Diffusion Model Based on Time and Distance in Industry Cluster

以创新和扩散为导向的集群经济效益已成为产业集群的竞争优势所在。基于时间和空间距离因素,构建了产业集群内的技术创新空间扩散模型,应用数据仿真实验,分析了在集群内进行技术创新空间扩散的动态过程,探讨了模型参数变化对技术创新扩散的影响,并着重分析了空间距离对技术创新扩散的影响。结果表明,产业集群内的技术创新扩散是典型的时空统一扩散过程,空间距离会阻碍技术创新的扩散,而且集群内采用技术创新的企业数量与距离因素呈负指数关系,为客观地预测和控制产业集群内时空统一的技术创新扩散过程提供了理论依据。

Cluster economic benefit oriented by innovation and diffusion has become competitive advantage for industrial cluster. Based on the two factors of time and space distance, the paper constructs technological innovation spatial diffusion mathematical model, applies date simulation, and studies the technological innovation spatial diffusion dynamic process within industrial cluster. Then it discusses how the change of parameter influences the technological innovation diffusion in space and analyzes how the change of space length influences diffusion process. The results indicate that technological innovation diffusion is a typical time-space unifies to spread the process, space distance can hinder the process of diffusion and the amount of enterprises adopting to technological innovation taking on negative index with distance in industrial clus- ter, to supply theoretical evidence to objectively reflect the essence of technological innovation diffusion process in space.
