差错责任追究制度在公司内部治理中占据重要地位,然而其可能产生的非预期效应却常被忽视。基于股价同步性独特视角,利用2007-2022年间A股上市公司的数据,深入探讨了这一问题,并通过构建双重差分(DID)模型,精确分析了差错责任追究制度对股价同步性的影响。研究结果显示,实施该制度后,公司的股价同步性显著提升,尤其是在那些应计盈余管理减少但真实盈余管理增加,以及年报可读性降低的公司中,这一效应更为显著。进一步研究发现,管理层持股较少、分析师跟踪较少的公司,受该制度的影响更为明显。此外,股价同步性的提高导致了公司权益资本成本的增加和投资者信心的降低。研究揭示了差错责任追究制度可能引发管理层盈余管理和信息披露的策略性行为,从而降低股票定价效率。代理冲突和外部监督的缺失是诱导这些非预期效应的关键因素。研究结果不仅深化了对公司内部治理机制非预期效应的理解,而且为监管机构制定相关政策提供了重要的参考,以警惕并应对可能的非预期后果。
