Abstract: In view of the unequal status of enterprises,there is a two-way relationship between supply chain nodes,resulting in uneven distribution in the process of interrupting risk transmission.Nodes with lower status will be more threatened.The whole process emphasizes dynamic allocation,and the tradition static supply chain vulnerability research methods are not applicable.Aiming at the dynamic allocation behavior of interrupted risk transfer process,based on the unequal supply chain topology network,the dynamic risk transfer model with joint failure theory was established,which included the node bearing capacity and risk transfer mechanism.The improved information entropy was used to determine the supply chain vulnerability assessment index.Through the analysis result of the example,the equal network was not the best strategy for the establishment of supply chain.Changing the two-way relationship between enterprises could effectively reduce the vulnerability of the supply chain and provide a theoretical basis for the establishment strategy of supply chain network.

Key words: unequal status, supply chain vulnerability, cascade failure, interrupt risk, dynamic transfer
