审计定价影响因素研究——来自中国上市公司首次审计费用披露的证据

The Determinants of Audit Fee: Evidence from Chinese Stock Market's First-time Disclosure of Audit Fee

长期以来我国会计师事务所对上市公司的审计收费都不为外界所知。2001年年报开始,证监会要求上市公司披露这一事项,本文以282家公司2000和2001年报作为样本,研究上市公司审计费用及其变动的影响因素。研究发现:(1) 关于审计费用定价,影响因素包括公司规模、是否由国际5大所审计以及被审计公司ROE是否处于"保资格"区间;(2) 关于审计意见与审计费用之间的关系,负面审计意见在2001年与审计费用显著相关,但被出具带解释说明段的无保留意见与审计费用不存在显著相关关系,因此不能从审计费的角度证实公司支付高额审计费进行审计意见类型变通之明显存在;(3) 关于审计费用之变动,影响因素包括公司规模的变动、审计意见由"不干净"变为"干净"、ROE的变动等3个。

From year 2001, the listed firms have been required to disclose the audit fee. The data for this paper consists of 282 observations on audit fees and related variables obtained from the listed firms that followed the requirements of the CSRC. Our first finding is that the size of the auditee, audited by the Big 5, ROE between 0-2% significantly influence the audit fee. Our second finding is that the negative opinion has significant effect upon the audit fee. Our third finding is that the change of the auditee size, the audit opinion modification, the change of ROE, all above have significant effect on the change of audit fee between years.
