摘要 根据供应链网络演化的内在动态机制及一些重要影响因素,建立了供应链网络演化的空间加权网络模型。在模型中,不仅考虑了成员企业之间契约关系的强弱,还考虑了空间距离因素对供应链网络演化过程的影响。通过对宏观统计特征的分析,探讨了供应链网络在大规模突发事件环境下的结构稳定性。结果表明:供应链网络对于随机性突发事件来说具有很大的结构鲁棒性,而对于蓄意攻击的突发事件则显得比较脆弱。因此,在供应链管理中应尽可能采取一切措施保护核心企业和关键供应关系。 Based on the internal mechanism of structural evolution and factors affecting the structural evolution, this work establishes the spatially weighted network model of structural evolution of supply chain network, where we not only consider the intensity of relationship among the finns of supply chain network, but also take into account the geographical factor affecting the process of structural evolution. By analyzing the macro-statistical characteristics, we investigate the structural stability of supply chain network under the situation of large-scale paroxysmal events. We show that supply chain network exhibits high structural robustness under the situation of random attack and exhibits low structural robustness under the situation of intentional attack. Therefore, the supply chain managers have to protect the key firms and relationships for long-term development.
