摘要：合理评价物流服务供应链脆弱性是实现网络高效率的重要前提。分析物流服务供应链网络节点作用规律，引入聚集系数、最大连通度及连通效率作为网络脆弱性测度指标，基于所构建攻击策略对二级物流服务供应链网络进行实例研究。结果表明：所构建指标可较好描述物流服务供应链网络脆弱性能变化；相较于功能型物流服务供应商与物流客户，物流服务集成商对网络脆弱性影响程度最大。最后提出物流服务供应链网络脆弱性的有效防范对策。

Abstract: Considering hierarchy and complexity of logistics service supply chain network system, complex network vulnerability of logistics service supply chain is studied. First of all, two-level basic framework of logistics service supply chain is extended to multi-level complex network, and interaction law of internal nodes is analyzed. Secondly, network clustering coefficient, largest connectivity and network connectivity efficiency are introduced as measure indicators of vulnerability of logistics service supply chain network. Then, according to different nature of nodes, attack strategies of logistics service supply chain network are established. Finally, the paper takes two-level logistics service supply chain network as an example to carry on empirical research, and effective preventive strategies of logistics service supply chain network vulnerability are put forward.. Results show that: the constructed complex network can be used to characterize vulnerability level of logistics service supply chain network; compared to attack result of logistics service provider and logistics customer, performance index of attack logistics integrator is zero; the impact of network vulnerability is the largest.
