摘　　要：基于BA网络模型构建了一种包括节点进入、退出和补偿机制的供应链网络演化模型。首先运用连续域理论求解该模型的度分布解析表达式;其次,使用Matlab进行仿真,并计算出模拟网络的度分布;最后研究供应链演化与生命周期的关系。理论解析结果和仿真结果均表明,节点度分布服从幂律分布,供应链网络具有无标度性。同时,发现厂商进入、退出和补偿的速度决定了供应链网络所处生命周期的阶段。The supply chain network is complex. Based on the BA network model,the evolution model of supply chain network was constructed,which included nodes entrance、deletion and compensation rewiring from the perspective of complex networks. Firstly the degree distribution analytic expression of the model was solved by using the mean-field theory. Secondly,the supply chain network evolution process was simulated using Matlab,and the degree distribution of the network was calculated. Lastly the relationship evolution of the supply chain and the life cycle was researched. Theoretical analytical results and simulation results show that the node degree obeys power-law distribution,and supply chain network is scale-free. And the speed of nodes entrance、deletion and compensation rewiring decide the different stages of the life cycle.
