我国上市公司IPO中审计质量与盈余管理实证研究

Audit quality and earnings management for China IPO firms

本文关于我国上市公司首次公开发行股票中审计质量与盈余管理之间的关系进行研究,旨在揭示大型会计师事务所审计是否可以约束IPO过程中的盈余管理动机,以及高品质的专业审计是否可以作为IPO实施过程中较少出现盈余管理的有效证据。通过非预期应计利润指标直接检验审计质量对盈余管理程度的影响,运用修正的琼斯模型和Logistic回归分析,采用SPSS统计软件进行数据分析得出结论：我国IPO市场上经“十大”会计事务所审计的公司,其盈余管理程度低于“非十大”审计的公司；专业审计师能够有效抑制IPO中盈余管理动机,降低盈余管理的程度。

This paper investigates the relationship between audit： quality and earnings management for China IPO firms to research ＂Do big auditors constrain earnings management in the IPO process？＂and＂Do industry specialist auditors provide higher quality audits in the IPO process as evidenced by less earning manage ment？＂First use unexpected accruals in the modified Jones model to measure earnings management in the IPO process. Then use Logistic regression model and SAS statistic software to found that big ten auditors are related to less earnings management in the IPO year in China. This shows that higher quality auditors constrain earnings management for Chinese IPO firms.
