  4. According to the problem that the recovery rate is traditional treated as a constant or an independent stochastic variable by the classical credit risk pricing and management model, and problem that the negative correlation between the default probability and recovery rate is always neglected, this dissertation gets the exponential and logarithm regression models of default probablilty and recovery rate based on some empirical researches, and improves on several broadly applied credit risk models, such as structural hazard rate model, affine structure model, convertible bond pricing model and credit metrics model, and introduce the negative correlation between

    針對傳統的信用風險定價模型及信用風險管理模型將違約回收率看成是一個外生的常數或是一個獨立的隨機變量，而忽略回收率和違約概率之間的負相關性這一問題，本文應用相關實證研究得到了違約概率和回收率的指數和對數回歸模型，並對應用非常廣泛的結構化風險率模型、仿射結構模型、可轉換債券定價模型和creditmetrics模型進行了改進和拓展，在新模型中應用指數和對數函數引入了這兩個變量之間的負相關性。
