边效益因素下复杂供应链网络局域演化机制

针对一般复杂网络演化模型中节点连接测度不能很好地描述复杂供应链网络特性的局限性，将节点企业间的合作所带来的边效益引入复杂供应链网络的演化模型中，采用节点度与边效益作为节点择优连接的综合测度指标，构建了复杂供应链网络的局域演化模型与算法。然后通过仿真，并与有关文献的复杂网络演化模型进行对比，分析了复杂供应链网络的增长性、边退化性与节点消失性，说明该模型具有高聚集系数、较低平均路径长度、无标度性、小世界特性，而且很好地解释了现实供应链网络在不同时期的演化机制问题，同时给出了经济学解释，这有助于更好地分析现实供应链网络的相关特性。

A local-world evolution model of complex supply chain network under edge benefit

As the node connected measures in general complex network cannot accurately describe the complex supply chain network characteristics, by introducing the edge benefit between enterprises into evolution model of complex supply chain network, using the node degree and the edge benefit as the preferred comprehensive measure index node connection, local-world complex supply chain network evolution model and algorithm has been constructed. And then through the simulation and compared with the complex network evolution models in related literatures, this paper analyzed the complex supply chain network growth, degradation and disappearance of edge nodes. The result show that the model has a high clustering coefficient, lower average path length, scale-free, small world property, and can better explain the evolution mechanism of real supply chain network problems in different periods, and gives explanation in economics, and related characteristics of the reality supply chain network would be better analyzed.
