摘要:

从内外部治理机制探索影响股价信息含量的关键因素有助于改善股市信息效率。文章通过理论分析和实证检验,分别考察了注册会计师审计质量和内部控制质量对股价信息含量的影响以及两者在其中的相互作用。研究结果表明:高质量的注册会计师审计和内部控制均能显著提高股价信息含量,且两者在提高股价信息含量中存在显著的替代关系。采用替换关键变量、倾向得分匹配回归、Heckman两阶段模型和工具变量法等进行稳健性检验,上述结论不变。基于此,企业应当合理利用内外部监督资源不断改善股市信息效率,注册会计师要充分关注企业内部控制质量,降低信息不对称程度,维护资本市场秩序。

Abstract:

Exploring the key factors that affect stock price information content from both internal and external governance mechanisms can help enhance the efficiency of stock market information. This paper examines the impact of audit quality and internal control quality on stock price information content through theoretical analysis and empirical testing. The study finds that both high-quality audit and internal control can significantly enhance stock price information content, and there is a significant substitution relationship between the two in enhancing stock price information content. The results remain unchanged after robustness tests using replacement of key variables, propensity score matching regression, Heckman two-stage model, and instrumental variable method. Based on this, enterprises should reasonably utilize internal and external supervision resources to continuously improve the efficiency of stock market information, and auditors should pay sufficient attention to the quality of internal control to reduce information asymmetry and maintain the order of capital markets.

Key words: CPA (Certified Public Accountant) audit, internal control, stock price informativeness, stock market information efficiency
