In view of the fact that the assessment of group credit risk is more difficult and complex than that of general enterprises due to the complex and concealed relationship within the enterprise group, and that the structural relationship among the members of the enterprise group is consistent with the scale-free network structure, the mechanism of credit risk contagion within the enterprise group is analyzed by applying grey theory and probability theory under the scale-free network structure. The research shows that the contagion threshold of credit risk within an enterprise group is related to the maximum contagion capacity of the member companies within the group. The stronger the maximum contagion capacity, the smaller the contagion threshold, the more likely the credit risk is to be contagious among the members within the group. The contagion threshold of credit risk among members of a group is independent of the size of the group.
