投服中心行权的威慑效应研究——基于分析师预测的视角

The Deterrent Effect of China Securities Investor Services Center's Shareholder Rights Exercise: From the Perspective of Analyst Forecasts

  • 摘要: 厘清投服中心行权的威慑效应如何形成和传导,对提高保护中小投资者质效有重要意义。本文手工搜集投服中心行权事件数据,从分析师预测视角考察了投服中心行权的威慑效应。研究发现,投服中心行权提升了同行业同地区其他未被行权公司的分析师预测准确度。一方面,基于声誉压力和竞争压力,未被行权公司将主动改善信息披露质量,为分析师预测提供更好的信息基础;另一方面,投资者对公司的信息需求增加,提高了分析师对这类公司的关注度,促进了分析师间的相互竞争和信息外溢。进一步分析发现,投服中心行权的威慑效应在被行权公司行业地位更高、行权事件市场反应更负面以及行权关注的问题涉及信息披露的样本中更显著。此外,投服中心行权还降低了同行业同地区公司分析师预测乐观偏差和预测分歧度。本文为强化投服中心功能作用发挥、改善资本市场信息环境提供了启示。

     

    Abstract: Elucidating the formation and transmission mechanisms of the deterrent effect arising from the China Securities Investor Services Center (ISC)'s exercise of shareholder rights bears significant implications for improving the quality and efficacy of minority investor protection. Based on manually collected data on ISC's shareholder rights exercise events, this paper examines the deterrent effect of ISC's shareholder rights exercise from the perspective of analyst forecasts. The study finds that ISC's shareholder rights exercise improves the analyst forecast accuracy for other non-targeted companies in the same industry and region. On one hand, driven by reputational and competitive pressures, non-targeted companies proactively improve their information disclosure quality, providing a better information foundation for analyst forecasts. On the other hand, increased investor demand for information about companies enhances analyst attention to such companies, promoting inter-analyst competition and information spillovers. Further analysis reveals that the deterrent effect of ISC's shareholder rights exercise is more pronounced in samples where the targeted company has higher industry status, market reactions to the rights exercise events are more negative, and the issues addressed by the rights exercise involve information disclosure. Additionally, ISC's shareholder rights exercise also reduces analyst forecast optimistic bias and forecast dispersion for companies in the same industry and region. This paper provides insights for strengthening the functional role of the China Securities Investor Services Center and improving the information environment of capital markets.
