中文摘要：

采用系统动态学的反馈环路分析方法，给出产业集群企业层面和整体层面的系统结构模型，分别描述了集群内企业的竞合机制和整个集群与需求、资源之间的关系。模型中的反馈环路反映了集群的主要系统结构，并分析了集群生命周期各阶段的主导反馈关系。依据各阶段主导反馈关系的分析，给出欠发达地区在集群发展各阶段的策略建议。

英文摘要：

After stating the literature review and systematic characteristic of industrial cluster, this study presents systematic structure models for industrial cluster on the level of enterprises and whole cluster, based on the System Dynamics, to describe enterprises＇ competitive and cooperative mechanisms in the cluster and relations among the whole cluster, demand, and resources respectively. The feedback loops in models reflect and explain the systematic structure of cluster mainly, and the dominant ones vary in different stages of cluster life cycle. According to the systematic characteristic and different dominant feedback loops in systematic structure models, the strategie suggestions of undeveloped regions are presented for the cooperation, coordinative competition of enterprises, and the whole cluster development respectively.
