在复杂动态环境下，知识协同行为（KCB）是产业集群创新（ICI）活动的有力支撑，构建复杂动态环境下产业集群创新中的群体知识协同行为模型具有重要的理论意义和实践价值。在分析复杂动态环境下产业集群创新与群体知识协同行为耦合规律的基础上，构建了复杂动态环境下产业集群创新中的群体与协同行为模型（CDEIKCBM）。与已有研究相比，该模型不仅可以反映随时间不断变化的动态演化规律，也可反映复杂动态环境下产业集群创新和群体知识协同行为的内在关联本质，有助于揭示二者的循环反馈关系。

In complex dynamic environment,knowledge collaboration behavior(KCB) is powerful support for activities of industrial clusters innovation(ICI).It is of great theoretical and practical significance to construct knowledge collaboration behavior model of industrial cluster innovation in complex dynamic environment(CDEIKCBM).Based on the analysis of the coupling law of industrial cluster innovation and knowledge collaboration behavior (including "factor coupling","target coupling" and "process coupling"),this paper constructs a knowledge collaboration behavior model of industrial cluster innovation in the complex dynamic environment (CDEIKCBM).Compared with previous studies,the model not only reflects the dynamic evolution law of the changing time,but also reflects the intrinsic relation nature of industrial cluster innovation and knowledge collaboration behavior.Thispaper also reveals the "circular feedback relationship" between KCB and ICI.This study can provide useful help and inspiration for the related research of industrial cluster innovation.
