摘　　要： 股权稀释效应和债务杠杆作用可通过改变股权价值和风险影响可转债价值,从而对可转债定价的产生综合影响。基于认股权证定价模型,本文建立了含可转债稀释效应和杠杆作用的可转债定价模型,并讨论了债务杠杆作用下基于MM理论的波动率修正方法。理论分析和数值算例表明,可转债价值受稀释效应和杠杆作用综合作用影响,稀释效应和杠杆作用对可转债价值分别产生正向和负向的影响。在可转债定价中同时考虑稀释效应和杠杆作用及其修正方式为可转债定价提供了一种新的思路。 Dilution effect and debt leverage may change the price and risk of shares and have effect on the value of convertible bonds. This paper builds up two models to price the convertible bonds with dilution effect and debt leverage based on some models of warrants value. It also proposes a method to correct volatility with historical volatility based on the M-M models. The theoretical and numerical analysis taken argues that dilution effect and debt leverage can affect the value of convertible bonds. Dilution effect may have a negative effect on convertible bonds, while debt leverage may have positive effect. This model offers a new idea of pricing convertible bonds.
