3、urn Percentage）、Amihud非流动性因子（Amihud Illiquidity Factor）等具有代表性的流动性指标进行实证分析，说明其对债券收益率价差的解释力度，从而评价不同流动性指标在公司债券市场上的表现。简言之，本文运用美国债券市场上的公司债券的交易数据评价了不同的流动性指标，评价标准是该指标对收益率价差的解释程度。文章共分为六章：第一章是引言，简要介绍本文的研究选题、主要观点、结构安排与研究方法。作者认为，公司债券流动性的研究无论是对于学术界还是业界都具有深远的意义，并且关于不同流动性指标对于收益率价差的解释力度问题一直以来没有确定的结论。因此，作者选择此方向为研究课

4、题。文章的第二章是文献综述，主要从流动性的测度指标、流动性影响因素、流动性因子与公司债券收益率价差之间的关系等几个方面对前人的研究进行综述。文章的第三章是关于实证方法和变量阐述。第四部分是数据和样本的描述。第五章主要是运用平均相关分析、债券组合和回归分析方法等做实证检验。第六章主要是说明了文章的缺陷以及进一步研究的方向。通过分析论证，文章的结论为：流动性因子在影响公司债券收益率价差方面起到了重要的作用。不同流动性指标对收益率差的解释力度是显著不同的，在文章研究的流动性指标中，零收益率百分比最好。文章的创新处有三点：运用公司债券的现时交易数据；将Amihud非流动性因子引入到公司债券市场流动性的
