The firms located in industrial cluster are important ties that linked the local industrial cluster and the global production network. They are as well as the micro-dynamics for the clusters' upgrading and evolution in the context of economic globalization. The existing researches on industrial cluster almost focus on the cluster's competitive advantages as a whole unit, which has supposed the firms in clusters are homogeneous and opportunity equipotent that can get extra advantages compared to the un-clustered firms.

集群企业正成为联系地方产业集群与全球生产网络的重要纽带，是经济全球化背景下产业集群升级和演进的微观动力；从已有的集群理论研究成果来看，目前的研究主要集中于集群整体层面，研究的焦点是对集群整体的竞争优势进行探讨，集群企业被假定为是具有同质性和机会均等性的，相对于非集群企业可以获得一种"非对称"的特殊竞争优势。
