摘　　要：突发事件严重影响企业生产、社会稳定和经济繁荣,而供应链中断是各类突发事件的直接结果,对供应链节点企业和供应链整体均带来多重负面影响.文章针对供应链中断风险传导路径的复杂性特点,引入小世界网络,定性判断了小世界网络方法的适用性,然后就供应链中断风险传导路径对供应链中断风险传导速度、供应链中断风险传导广度和供应链中断风险传导稳定性三方面的影响进行了研究和数值模拟分析,验证了供应链中断风险传导路径的小世界特性.研究发现,较短的中断风险传导路径和较大的集聚系数均能有效提升供应链网络的中断风险传导速度,核心节点企业的稳定性对供应链中断风险传导过程中供应链网络整体的稳定性起到至关重要的作用.此研究有利于供应链节点企业和供应链整体应对中断风险并提升运作效率.The emergent events exert a significant impact on the corporate production, social stability, and economic prosperity. As the direct result of various emergent events, supply chain disruption brings multiple influences to the node enterprises in the supply chain and the supply chain as a whole. This study investigates the complexity of supply chain disruption risk conduction route, and introduces the small world network to qualitatively evaluate the applicability of the method of the small world network. Then, it is concerned with the impact of supply chain disruption risk conduction route on the speed, breadth and stability of supply chain disruption risk conduction, together with the numerical simulation analysis, which verifies the nature of the small world network relating to the supply chain disruption risk conduction route. Research has shown that the shorter disruption risk conduction route and larger aggregated coefficients are able to increase the speed of disruption risk conduction in the supply chain network. It has also shown that the stability of key node enterprises plays a pivotal role in stabilizing the whole supply chain network in the process of supply chain disruption risk conduction. The findings of this study could benefit the node enterprises on the supply chain and the supply chain as a whole in terms of the management of the disruption risks and the improvement of the operation efficiency.
