基于Nooteboom模型构建网络中企业间创新合作的博弈模型,确定企业合作伙伴数的临界值,结合复杂网络模型仿真企业网络的动态演化,研究企业网络结构与合作度的变化规律。结果表明,企业合作的临界伙伴数由合作收益、成本及风险决定。当企业合作伙伴数小于临界值时,合作是最优策略,且随着合作度增加,合作网络的特征路径长度缩短,集聚度下降网络出现均匀而致密的结构;在合作的伙伴数等于临界值时,网络中的合作度最大,结构趋于稳定。
Based on the Nooteboom model, this paper constructs a game model of innovation cooperation among enterprises in the network, determines the critical value of the number of partners in the enterprise, and simulates the dynamic evolution of the enterprise network based on the complex network model to study the changing rules of enterprise network structure and cooperation degree. The results show that the number of critical partners in business cooperation is determined by the benefits of cooperation, costs and risks. When the number of business partners is less than the critical value, cooperation is the optimal strategy, and as the cooperation increases, the length of the characteristic path of the cooperation network is shortened, and the degree of concentration decreases. The network has a uniform and compact structure. When the number of partners is equal to the critical value When the degree of cooperation in the network is the largest, the structure tends to be stable.
