摘要: 企业环境信息透明度和真实性对资本市场的定价效率有重要影响。然而,企业的环境信息粉饰行为可能会对资本市场的定价效率产生不利影响。利用2008—2023年发布社会责任报告的沪深A股上市公司的数据,考察了企业环境信息粉饰行为对资本市场定价效率的影响及其作用机制。研究发现,企业环境信息粉饰行为显著降低了资本市场的定价效率。机制分析显示,企业环境信息粉饰行为会降低企业的信息披露质量和助涨投资者的非理性情绪,因而企业环境信息粉饰行为会降低资本市场的定价效率。异质性分析显示,在环境规制强度小时,企业环境信息粉饰行为对资本市场定价效率的降低作用更显著;在分析师关注度高的企业中,这种降低作用也更显著。为此,监管机构要推动环境信息披露从数量合规向质量可信转变,并要实施差异化的监管策略,提升监管的精准性与威慑力。

关键词: 环境信息粉饰行为, 资本市场定价效率, 信息质量, 投资者非理性情绪

Abstract: The transparency and authenticity of corporate environmental information exert a significant impact on capital market pricing efficiency. However, environmental information embellishment behavior may adversely affect capital market pricing efficiency. Drawing upon comprehensive data from A-share listed companies that have published corporate social responsibility reports between 2008 and 2023, this study examines the impact and mechanism of environmental information embellishment behavior on capital market pricing efficiency. Research indicates that environmental information embellishment behavior significantly undermines capital market pricing efficiency. Mechanism analysis reveals that environmental information embellishment behavior reduces corporate information quality and amplifies investors’ irrational sentiment, thereby diminishing capital market pricing efficiency. The heterogeneity analysis reveals that this negative effect is more pronounced when environmental regulation intensity is weak and in firms with high analyst coverage. Therefore, regulators should promote a shift in environmental information disclosure from quantitative compliance to quality credibility, adopt differentiated regulatory strategies, and enhance the precision and deterrence of supervision.

Key words: environmental information embellishment behavior, capital market pricing efficiency, information quality, investors’ irrational sentiment
