The information related to enterprises’ credit level will disseminate among entrepreneurs through their relationships. Entrepreneurs with different risk attitudes may make different decisions even if they face the same information, which will affect the credit risk contagion among enterprises. This paper constructs a dual-layer network to describe relationships among entrepreneurs and enterprises, and builds a credit risk contagion model with the influence of information dissemination, then investigates the influence factors on the credit risk contagion by simulation analysis. The results are as follows: (1) The threshold of credit risk contagion is negatively correlated with the possibility of losing immunity and positively correlated with the possibility of recovery; (2) The number of infected enterprises decrease with the increasing of the social rate and dual-layer network similarity; (3) Strengthening information dissemination among entrepreneurs can control credit risk contagion among enterprises.

与企业信用水平相关的信息将通过企业家之间的关系在企业家之间传播。不同风险态度的企业家即使面对相同的信息也可能做出不同的决策，从而影响企业之间的信用风险传染。本文构建了一个双层网络来描述企业家与企业之间的关系，并构建了一个受信息传播影响的信用风险传染模型，然后通过模拟分析研究了信用风险传染的影响因素。结果如下：（1）信用风险传染阈值与失去免疫力的可能性呈负相关，与恢复的可能性呈正相关；(2) 感染企业数量随着社会化率和双层网络相似度的增加而减少；(3)加强企业家之间的信息传播，可以控制企业之间的信用风险传染。
