银行作为债权人将资金放贷给企业，企业无法按时偿还本金，由此带来的风险称为信用风险。本文选择了44家配对上市公司，采用KMV模型对上市公司的信用风险进行度量，实证结果显示，KMV模型对于度量上市公司信用状况具有一定的适用性，但如果将KMV模型与PFM模型相结合，KMV模型使用的范围更加广泛。针对外部信用风险产生的原因，本文还给出了减小外部信用风险的建议。%Banks, as the creditors, will fund lending to the enterprises, and if the enterprises can't timely repay the principal, the risk known as credit risk will be resulted.
