The promotion of innovation is considered a kind of important advantage o f cluster of enterprises,which is a unique industrial organization fo rm.But the existing literatures care little about the integration innov ation between various organizations inside the cluster.Based on the survey of the deve lopment of the clusters of enterpris es in Zhejiang Province and the theoretic al discussion of the coupling modes i nside clusters,this thesis demonstrates the effects of integration innovation h aving on the cultivation of sustainable advantage in clusters.In order t o realize the integration of innovation,two issu es earn our attention:one is that the members in clusters should carry out the effect of knowledge sharing through the harmonious process of cluster learning;the other is that we need competitiv e mechanisms incenting the members to innovate one after another,forming the effect of extrusion.At last,the thesis discusses the effective governance arrangements to promote the integra tion innovation in clusters.
