中文摘要：

企业集群作为大中小企业及相关机构在地域集聚所形成的产业网络组织可以划分为均衡型、核心企业型、供应主导型、中介企业型、密集网络型等，网络结点内成员间、结点间的交互作用促使成员单位的竞争力提升，从而提高集群对环境的适应能力．本文应崩NK模型对不同类型和进化模式的集群进行适应度模拟分析，得到集群的局部和全局适应度最优值，揭示企业集群演变的规律，并提出政策建议．

英文摘要：

As an industrial network organization formed by geographical gathering of enterprises and related institutions, business cluster could be divided into the types of chain-balanced, core business, supply-dominated, business agency, and dense network. The interaction among members within and between nodes can promote their competitive strength, and further increase the adaptability of the whole cluster to the environment. It applies the NK model to make the fitness simulation analysis on different types and different evolution modes of clusters, and gets the local and global optimal values of business cluster fitness. It reveals the evolution law of business cluster, and puts forward relevant policy suggestions.
