【摘要】 本文以中国2016—2020年发行的信用债为研究样本，实证分析债券发行主体所在行业的信用风险事件是否以及如何影响新券发行成本。研究发现：(1)外部违约事件会显著提高同行业新发行债券的融资成本，上述发现在控制发债主体和债券特征变量、增加多种固定效应、改变时间窗口以及采用倾向性得分匹配后仍显著存在；(2)投资者的“恐慌效应”是行业违约事件影响新券发行成本的主要作用渠道，具体表现为在信息披露不足、非国有企业、主体评级较低和地区法律环境较差的发债样本中违约的外部性更强；(3)信用风险事件的定价影响在同类型债券违约和行业首次违约样本中更加明显，而且随违约次数增加而加强。本研究从企业融资成本的视角为理解和认识信用风险行业外部性增加了实证证据。更多还原

【Abstract】 In order to find out whether and how the emerging corporate bond default events affect newly issued bonds’ pricing, this paper studies the credit bonds issued from 2016 to 2020 and reaches three conclusions:(1) Default significantly increases the cost of newly issued bonds for the issuers within the same industry, and these results remain statistically significant after controlling bond and firm characteristics and a set of fixed effects, changing the event window, and implementing propensity score matching;(2) The underlying mechanism is enabled by investors’ “panic pricing effect”. Specifically, issuers who are lacking information disclosure, non-state owned, low-rated, and exposed to a poor legal environment suffer more from the externality;(3) The credit-event driven risk premium is more obvious in the samples of the same type of default bond, and the samples affected by the industry’s first default. The number of defaults is also significantly priced. From the perspective of corporate financing cost, this paper empirically contributes to understanding the intra-industry externalities of credit risk.更多还原
