中文摘要：

以集群产业链中上、下游企业创新链接的关键环节＂谁负责创新＂作为研究的着力点,尝试运用数量生态学中的进化博弈模型,对集群上、下游企业的创新链接机制进行剖析和研究。博弈分析的结果显示：集群企业＂创新型进化＂具有自我维持的特征,集群群落中已有的＂创新型＂企业的占有率、下游企业对上游企业的依赖程度以及政府采取的补贴、知识产权保护等因素对集群企业向＂创新型＂企业＂种群＂方向演化具有催化作用。

英文摘要：

Making the key link ＂who is responsible for innovation＂ as the focus of the study of cluster chain in the upstream and downstream,this paper tries to use quantitative ecology of evolutionary game model to analyze and research the innovative link mechanism upstream and downstream enterprises.Game analysis showed： cluster enterprise ＇innovative evolution＇ has the characteristics of self-sustaining;cluster communities of ＇innovative＇ company share,reliance of downstream to the upstream enterprise,government＇s subsidies and intellectual property protection and other factors promote cluster enterprises to ＇innovative＇ enterprises ＇population＇ as direction of evolution.
