摘要: 债券违约背后隐藏的发债企业的违法行为严重扰乱了债券市场秩序。那么,作为一项监管型小股东开展行权活动的投资者保护制度,投服中心能否对债券市场产生溢出效应?基于此,以2016—2023年沪深A股上市公司公开发行的债券为样本,实证检验投服中心行权对债券信用利差的影响。研究发现,投服中心行权显著提升了债券信用利差。机制分析表明,投服中心行权能够发挥信号效应,将上市公司治理和资金情况较差的信号传递给债券投资者,从而增大债券信用利差。异质性检验发现,当地区信用环境薄弱、企业对投资者的保护程度较低、投资者学习效应不足时,投服中心行权对债券信用利差的提高作用更为突出。此外,投服中心行权增加了债券一级市场的发行成本,并且在扩大二级市场债券信用利差后还加大了企业面临的财务风险。因此,上市公司要持续完善信息披露,增强自身在债券市场中的议价能力;监管部门则要借助投服中心的行权活动防范化解系统性金融风险,从而推动资本市场实现高质量发展。

Abstract: The illegal activities of the bond-issuing enterprises hidden behind bond defaults have severely disrupted the order of the bond market. So, as an innovative investor protection system for regulatory minority shareholders to carry out right exercise activities, can China Securities Investor Services Center (CSISC) produce a spillover effect on the bond market? Based on this, taking the bonds publicly issued by Shanghai and Shenzhen A-share listed companies from 2016 to 2023 as samples, this paper empirically examines the impact of CSISC's exercise of rights on the credit spread of bonds. The research reveals that CSISC's exercise of rights has significantly increased the credit spread of bonds. The mechanism analysis shows that CSISC's exercise of rights can exert a signal effect, transmitting the signal of poor governance and capital situation of the listed companies to bond investors, thereby increasing the credit spread of bonds. The heterogeneity test reveals that when the regional credit environment is weak, the degree of protection for enterprise investors is relatively lower, and the investor learning effect is insufficient, CSISC's exercise of rights has a more prominent effect on enhancing the credit spread of bonds. In addition, CSISC's exercise of rights has increased the issuance cost of bonds in the primary market and exacerbated the risks of financial distress it faces after raising the credit spread of bonds in the secondary market. Therefore, the listed companies need to continuously improve their information disclosure and enhance their bargaining power in the bond market. The regulatory authorities should use the right exercise activities of investment service centers to prevent and resolve systemic financial risks, thereby promoting high-quality development of the capital market.

Key words: exercise of rights by CSISC, bond credit spread, investor protection, spillover effect
