审计委员会的设立与公司治理——基于审计收费的实证研究

采用非参数检验方法和回归分析方法,本文从审计费用率视角研究了审计委员会的设立对上市公司治理的影响。本文发现,在设立审计委员会的样本和未设立审计委员会的样本之间,董事会的规模和独立性、独立董事规模和报酬存在显著差异,且这些变量及独立董事规模、审计任期与审计费用率的相关性不同。结果表明,审计委员会在加强独立董事责任和董事会、外部审计师独立性的同时,也改善了公司内部控制系统,但整体上并没有改变审计师的任期。

The Formation of Audit Committee and Corporate Governance——Empirical Research Based on Audit Fee

Appling non-parameter tests and regression model,this paper studies the impact of formation of audit committee on board characteristics and the relation between board characteristics and the ratio of audit fee to asset.We find that the board size and independence,the number and remuneration of independent directors of board with audit committee are significantly different from that of board without audit committee,and that board independence,number and remuneration of independent director,and number of non-independent director are significant association with ratio of audit fee to asset for listed firm with audit committee,and auditor's tenure is significant association with ratio of audit fee to asset for listed firm without audit committee.Our results show that audit committee strengthens independent director's responsibility and promotes board and auditor independence as well as it improves firms' internal control system,but it don't change average tenure of auditor.
