焦点企业的发展离不开作为网络组织的企业集群，基于焦点企业的企业集群已经成为区域经济发展和技术能力提升的重要支柱。然而现有文献大多关注企业集群内部的网络结构及其共生关系，较少研究企业集群间共生关系的网络特征，也就不可能系统归纳共生网络的阶段性演化过程，难以获取共生网络的动态演化规律。本项目研究遵循复杂适应系统（CAS）分析思维，将基于焦点企业的企业集群间共生网络视为复杂网络组织，以共生网络结构描述及演化刻画为研究主线，结合国内外典型案例研究，并引入动态仿真技术和社会网络分析方法，构建共生网络演化过程的回声模型和演化动力模型，挖掘并获取共生网络的演化规律及机理，并对演化模型的仿真结果进行验证，从而为基于焦点企业的企业集群间共生网络的演化治理及政策设计提供理论支持。

The development of the focal firms can not be separated from the enterprise clusters, which are generally taken as network organizations. The enterprise cluster based on focal firm plays an important role in the regional economy developing and technical capacity promoting. However, most of the existing literatures concentrate on the inner network structures of enterprise cluster and the symbiosis relationship among the sub-structures. They also neglect the characteristics of the symbiosis relationship among enterprise clusters, which reduces the possibility of summarizing the periodical process of evolution of the symbiosis network in a systematic way and makes it hard to acquire the law of dynamic evolution of symbiosis network. With an analytical thinking of complex adaptive system (CAS), this item regards the symbiosis network among the enterprise clusters based on focal enterprise as complex network organization. The main line of this study constitutes of a description of the symbiosis network and a portraying of its evolution. With the combination of the study of some typical cases all over the world and the adoption of dynamic simulation technology and analytical approaches of social network, our item constructs an echo model and a dynamic model of evolution. Both of the two models depict the evolution process of symbiosis network. By using the above two models, this item strives to mine and acquire the law and mechanism of symbiosis network. A test of the results of simulation of the evolution model will also been made. All of the works could provide theoretical support for the governance and policy design of the symbiosis network among the enterprise clusters based on the focal firm.
