| 摘 要： | 针对目前上市公司的日趋增多和广大投资者对于投资股市的热情,对上市公司的信用风险进行度量和评估已显得十分迫切和必要。运用KMV模型,从我国沪深两市中共选取三十家绩优股和绩差股,以2007年9月30日为基准日,运用三种方法计算其未来一年的违约距离DD(Default Distance)和预期违约频率EDF(Expected Default Frequency),在一定程度上可以对上市公司信用风险进行评估。分别采用了三种方法来计算违约距离并进行对比。实证分析结果表明,在KMV模型中引入资产连续回报率这个模型最适合中国国情,灵敏度和预测能力较好,在一定程度上可以揭示上市公司的信用风险。
