会计盈余信息有用性的研究都是以无差别的审计服务和盈余作为现金流的替代指标为前提的。本文放宽了这些假设,通过模型建立、实证研究,经验地研究了审计独立性与市场反应的关系。研究结果发现,除非预期盈余具有信息含量外,审计意见具有增量的信息含量,尤其是非标审计意见的影响。 The research on the usefulness of accounting earnings information is premised on indiscriminate auditing services and surpluses as surrogate indicators of cash flow. This paper relaxes these hypotheses and studies the relationship between audit independence and market reaction through empirical research and model building. The findings show that, unless the expected earnings have information content, the audit opinion has incremental information content, especially the impact of non-standard audit opinion.
