加权评分法、模糊评估法、多变量信用风险二维判断分析法是目前国外评级机构普遍使用的三种企业债券信用评级方法,这些方法相互交叉,各有特点。目前,我国企业债券信用评级方法较为落后,今后应借鉴国际主流评级方法,加强信用评级方法的动态性,重视数学,统一债券信用评级的基本方法等。
Weighted scoring method, fuzzy evaluation method and multivariable credit risk two-dimensional judgment analysis method are the three kinds of credit rating methods commonly used by foreign rating agencies. These methods cross each other and have their own characteristics. At present, the credit rating method of corporate bonds in our country lags behind. In the future, we should draw lessons from the international mainstream rating methods, strengthen the dynamic of credit rating methods, attach importance to mathematics and unify the basic methods of credit rating of bonds.
