摘　　要：基于企业在创新合作活动中的理性决策行为,建立创新网络动态演化模型。运用复杂网络研究中的数值仿真方法,研究创新网络的动态演化规律、企业间的知识溢出与网络结构的关系。研究放宽了创新网络博弈论文献对网络结构的不合理假定,同时又赋予网络演化一定的经济含义。研究发现:创新网络可自组织演化至稳定状态;知识溢出效率的提高可增进行业的收益水平,并激励企业积极地参与创新合作,但过高的效率值会加剧企业间收益分配的不平等;知识溢出效率不影响企业合作规模的分布;稳定状态下的创新网络为小世界网络,具有高的聚集系数和短的平均路径长度,但其并非利用效率最高的网络安排。In this paper, we present a dynamic evolvement model of innovation network based on rational decision -making behaviors of companies in the innovation cooperation. Using numerical simulation method, we explore the dynamic evolvement laws of innovation network and the relationship between knowledge spillover among companies and the network structures. We relax the irrational assumptions in the conventional innovation network game literature, and endow the network evolvement with certain economic explanations. The results demonstrate the innovation networks could self - organized evolve to stable state. The improvement of knowledge spillover efficiency can enhance the industry＇ s profit, and encourage the companies actively participate in the innovation cooperation. But too high spillover efficiency will enlarge the inequality of companies＇ profit distribution. The knowledge spillover efficiency has nothing to do with the cooperation size distribution among companies. The stable innovation networks are small - world networks, but they are not with the highest utilization efficiency.
