基于KMV模型的地方政府债券信用风险问题研究

借助于KMV模型的思想建立了地方政府债券信用风险模型,进一步探讨了模型的概率分布形态以提高模型的预测精度;并在确定预测标准后,针对2009年已发行地方政府债券的部分省市计算了各地安全发债规模。研究表明,基于KMV模型的地方政府债券信用风险模型具有很强的应用性和很好的推广前景;实践中,在对发债主体进行科学选择的基础上,通过该模型能实现对发债规模的控制,达到防止其发生信用风险的可能;同时,所选样本省市(除新疆外)的预测安全发债规模和实际发债额是合理的和安全的。因此,应建立一套科学规范的地方政府债券风险防控机制,以保证地方政府债券的健康发展。

Analysis on Credit Risk of Local Government Bonds Based on the KMV Model

Based on the KMV model,this paper established a credit risk model for local government bonds,and further study was made on the patterns of its probability distribution to improve its prediction accuracy.After determining the forecast standards,we calculated the safe issue volume of those provinces and municipalities who issued local government bonds in 2009.The research showed that the credit risk model based on the KMV model had a strong applied and very good promotion prospects.In practice,we can control ...
