Abstract: Evolution of microcosmic Knowledge Network(KN) is precondition and important part of evolution procedure of industrial cluster network.In this paper, firms in industrial cluster are classified as Task-lead and Knowledge-lead according to their preference of interaction among them.A Multi-agent-based model is constructed and simulated using Blanche software which is a tool for research of multi-agent networks.The characteristics and the effect to KN evolution of Task-lead KN and Knowledge-lead KN are analyzed based on the simulation of the model.Finally,the limitation of the research is concluded and the agendas are discussed for the future research.

Key words: industrial cluster, knowledge network, evolution
