摘　　要：基于银行主体和企业主体间银行信贷连接及企业主体间的商业信贷连接,构建了同时嵌入银企间市场和企业间市场的内生信贷网络模型。在构建过程中,对于企业主体的生产设置了双重约束,并引入分红、投资、存款波动等刻画相关主体行为,允许多期债务结构的存在,同时放松了相关学者的研究假设。内生信贷网络模型的仿真结果表明:企业规模的上尾服从幂率分布;银企信贷网络的银行入度服从双幂律分布。An endogenous credit network model is constructed,which introduces firm-bank and interfirm markets simultaneously,based on the bank loan links between the bank and firm agents and the trade credit links among firm agents. We set double constraints for firms＇ production. To further describe the behavior of the related agents,we introduce investments,dividend payments and deposit fluctuation into the model. Moreover,we also allow multi-period debt structures and relax some research assumptions made by related scholars. The simulation results show the upper-tail of firm size distribution can be well fitted with a power-law and the bank in-degrees of the firm-bank credit network fall into a two-power-law distribution.
