摘　　要：通过事件研究法计算可转债发行的超常收益,对可转债投资价值与财富效应之间的关系进行回归分析。研究表明,可转债的投资价值与财富效应显著正相关。另外,可转债股性凸显会引起财富效应增速上升,债性凸显导致财富效应增速下降。This paper uses factor analysis method,designs Z value,quantifies the value of convertible bonds,calculates the abnormal returns of convertible bonds through the event study method,and finally returns the regression analysis on the relationship between the value of the convertible bond investment and the wealth effect.The study finds that the investment value of convertible bonds has a significant positive correlation with the wealth effect.In addition,the value of the convertible bond is convexity through the mathematical derivation.The conclusion is that the growth of the convertibility will lead to the increase of the wealth effect,while the grouth of the indebtedness leads to the decline of the wealth effect.
