摘 要

2014年,上海、深圳两个证券交易所先后发布可交债券相关业务实施细则后,可交债券正式进入中国金融市场,距今已有近4年。可交换债券的发行对于缓冲解禁限售股、乃至完善中国金融市场有重要的作用。因此本文的研究对象是中国证券市场上的一种新型债券,可交换债券。在本文中,首先对可交换债券的定义、历史与理论基础做了介绍,并且与可转换债券进行比较;其次主要采用事件研究法对可交换债券对应正股上市公司的每日收盘价数据进行实证研究,此外还通过具体的案例分析对典型的“14宝钢EB”债券进行研究,以检验可交换债券发行是否不会对上市公司股价产生剧烈波动。

对可交换债券的正股样本的异常报酬率进行实证研究,结果表明可交换债券发行的公告效应影响不大,也就是发行可交换债券对标的股票股价基本无影响,佐证了可交换债券对于缓冲解禁限售股的积极意义。本文通过对14宝钢EB可交换债券的案例分析,阐明可交换债券发行主体的特征,更重要的是解释了可交换债券在融资成本、融资方式上的优越性,并提出推广可交换债券的建议。
