摘　　要：本文主要基于股权和关联交易形成有向赋权网络结构,并结合SIRS模型,构建企业集团内部风险传染模型研究集团内部的风险传染机制。研究发现,稳态时集团成员的状态与节点的度分布密切相关,受冲击节点的度越大,风险传染范围越广。进一步,通过对无标度网络的讨论,得出相关因素对集团内部风险传染的影响,并分析出治愈率是影响集团内部风险传染情况的关键因素。研究表明,集团通过减小有效传染率,增加集团消除危机的可能性,可以使集团的经营更加稳健。It is devoted to studying the transmission mechanism of risk within the group in this paper.Based on the relationship between equity and related party transaction,a directed weighting network structure is formed,and the model of risk contagion mechanism within enterprise groups is built by combining SIRS model.It is found that the state of group members in steady state is closely related to the degree distribution of nodes.The greater the degree of the impacted nodes,the wider the scope of risk contagion.Furthermore,through the discussion of scale-free network,it is found that the influence of related factors on the risk contagion within the group,and learned that the recovery rate is the key factor affecting the risk spread within the group.The research shows that the group can make its operation more stable by reducing effective infection rate and increasing the possibility of eliminating crisis.
