中文摘要:

      财务重述代表财务报告的低质量与不可信,会对资本市场产生负面效应。通过构建双重差分模型,考察已审报表被重述的执业经历对签字注册会计师的审计质量的影响。研究结果发现,与已审报表未被重述的签字注册会计师相比,已审报表被重述的签字注册会计师在财务重述之后审计质量明显提高。研究进一步发现,已审报表被重述对审计质量的提升作用仅体现在核心指标重述的样本以及重述年度与签字年度的间隔期相对较短的样本中。此外,被重述年度的签字注册会计师未发生变更的财务重述公司在重述前后的审计质量存在明显差异,这为签字注册会计师已审报表被重述的执业经历对审计质量的影响提供进一步的经验证据。上述发现可为证券监管部门、投资者等利益相关者提供参考。

英文摘要:

      Financial restatement represents the low quality and unreliability of financial reports, which will have a negative effect on capital market. By constructing a DID model, the impact of practice experience of restatement of audited financial statements on signing CPA's audit quality is investigated. The research results show that compared with those free from restatement of audited financial statements, the signing CPA whose audited financial statements are restated improves the audit quality significantly after financial restatement. It is further found that the improvement of audit quality by restatement of audited reports is only reflected in the samples with restatement of core indicators and the samples with relatively short interval between restatement and signing year. Further, we have found that audit quality of the companies which do not change signing auditor after financial restatement is significantly different before and after the financial restatement, which can supplement the experiential evidence of the main test. The above findings can provide references for securities regulatory authorities, investors and other stakeholders. 
