摘要
本文以中国某商业银行1814个小型工业企业贷款客户数据为样本,根据指标对违约状态鉴别精度的影响程度进行第一次筛选,保证遴选出的指标对违约状态鉴别能力都有显著影响;根据准则内相关分析进行第二次筛选,避免遴选出的指标反映信息重复,构建了一套能显著区分小型工业企业违约状态的评级体系。本文的创新与特色:一是根据有、无特定指标两种状态下、Fisher判别对违约状态鉴别精度的提高或降低,反映特定指标对违约状态的影响程度,剔除对违约状态的判别精度没有影响或有降低影响的指标,保留可以显著提高违约状态判别精度的指标,完善了现有研究遴选指标的标准与违约状态无关的不足。二是在相关系数大于0.7的两个指标中,根据对Fisher判别精度影响程度越大、这个指标区分违约状态能力越强的思路剔除对Fisher判别精度影响程度较小的指标,避免了现有研究在剔除冗余指标时、对违约状态影响大的指标可能被误删的不足。
