【摘要】 直接法和间接法是零息票债券收益率曲线推导的两种方法。直接法作为一种代数方法 ,尽管存在对样本数量没有过高要求的优点 ,但存在对样本点的选取条件过于苛刻的缺陷 ;间接法作为一种统计方法 ,对样本点的选取条件相对宽松 ,但对样本数量有一定的要求。在中国现有的债券交易格局下 ,推导零息票债券收益率曲线存在一定困难。更多还原

【Abstract】 There are two kinds of methods for deduction of zero coupon bond yield curve: direct method and indirect method. Direct method, which is an algebraic method, has overcritical requirement not for the sampling size but for the selection of the samples. On the other hand, indirect method, as a statistical method, has overcritical requirement for sampling size, but not for the selecting of samples. For Chinese finance market in current stage, there are many restraints for the deduction of zero coupon bond yield curve.更多还原
