摘要： 考虑了供应链网络中企业节点增加和脱离的情况，利用修正的BA模型分析了供应链网络演化中企业节点连接度的分布特征。研究表明，在供应链网络中，仅有少数核心厂商能够获得网络中大多数连接，其连接度的概率分布与其连接度成反比；结论指出，在供应链网络中的企业节点同步增加或删除的情况下，供应链网络中结点的连接度的概率分布服从参数为γ(1<γ≤2)的幂率分布，对大企业实施供应链战略管理提供了依据。

Abstract: With the frequent adding and escaping of nodes in supply chain network being taken into account, the scalefree characteristics of such networks is studied. For this purpose, the BarabasiAlbert (BA) model is modified to describe the system. With the modified BA model, the probability distribution of an enterprise nodes link degree in the network is analyzed. Results indicate that only a minority of core firms can capture the great majority of links from other firms and the probability distribution of the link degree is inversely proportional to its link degree. Also, when the nodes of firms are synchronously increases and deleted, the link degree probability distribution of nodes in the supply chain network follows power distribution with parameterγ(1<γ≤2). The results are helpful for largescale enterprises in strategic management in the supply chain.
