中文摘要：

知识溢出是形成产业集群的主要因素之一，知识溢出机理仍然是一个“黑箱”。针对高技术产业集群内的知识溢出，首先分析影响知识溢出各环节的因素，然后运用系统动力学模型，建立因素作用结构反馈模、型，揭示知识溢出的机理，得出在知识溢出过程中有六大反馈回路。

英文摘要：

Knowledge spillover is one of the main factors of industrial clusters formed,and knowledge spillovers mechanism is still a ＂black box＂. For high technology industry cluster,this paper first analyzes the influence factors of knowledge spillovers along the channel, and then use the system dynamics model to establish factors structure feedback model, reveal the mechanism of knowledge spillovers, and finally find that there are six feedback loops in the process of knowledge spillovers.
