Abstract: Industrial cluster research has the development tendency which is from macro to micro, from homogeneous to heterogeneity and from “structural-oriented” to “behavioral- oriented”. Under the view of “micro-heterogeneity” and “behavioral-oriented”, a very important heterogeneous body—“knowledge gatekeeper” and its behaviors have great effects on cluster’s upgrading. After defining the “knowledge gatekeeper” and “cluster upgrading”, the article think that knowledge gatekeeper’s knowledge behavior—knowledge absorption, knowledge translation and knowledge diffusion and knowledge gatekeeper’s strategic behavior—technology leapfrogging, network building and rule making drives the cluster upgrading together. Finally, the article gives some suggestions for Chinese cluster upgrading.

摘要： 产业集群研究呈现出从宏观到微观、从同质性到异质性、从“结构导向”到“行为导向”的深化发展趋势。在“微观异质”和“行为导向”的理论视角下，产业集群中一类重要的异质性主体——“知识守门者（Knowledge gatekeepers）”的行为对产业集群升级产生了重要影响。在对“知识守门者”以及产业集群升级内涵进行界定的基础之上，本文认为“知识守门者”的知识行为——知识吸收行为、知识转译行为与知识扩散行为以及“知识守门者”的战略行为——技术跨越行为、网络建构行为和规则制定行为共同驱动了产业集群的升级。文章最后给出了基于知识守门者行为的促进我国产业集群升级的政策建议。
