不利意见、审计费用与意见购买

本文进一步区分上年度不利审计意见的具体类型、审计费用的升降以及审计意见的改善与恶化。研究证实:(1)上年度被出具不利审计意见虽然可能增加本年度收到不利审计意见的可能性,但是亦可能提高审计意见改善的可能性,并和审计意见出现恶化的可能性显著负相关。(2)如果上年度被出具不利审计意见,则异常审计费用与审计意见改善的可能性显著正相关。(3)审计费用的增加能显著降低被出具不利审计意见的可能性,并可有效防止年报审计意见出现恶化。可见,公司管理层可以通过提高审计费用成功地实现审计意见购买动机,在一定程度上规避不利审计意见。     

审计委员会治理与审计意见

本文从审计委员会的存在性、独立性和勤勉程度三个方面,将审计委员会与审计师规模、异常审计收费、审计师变更等结合起来考虑,探讨审计委员会治理对上市公司年报审计意见类型以及不利审计意见改善和审计意见恶化的影响。研究表明,相对于审计委员会的存在性,审计委员会的独立性和勤勉程度对外部独立审计师审计判断及其所出具的审计意见的影响更为显著;在结合考虑审计师规模、审计收费、审计师变更等相关因素的前后均可以发现,在董事会中设立审计委员会并切实提高审计委员会的独立性和勤勉程度,不仅有助于提升上市公司财务报告的质量,而且亦有助于在一定程度上对管理层的审计意见购买行为进行有效的制衡。     

客户相对规模、非诉讼成本与审计意见决策

通过对2004年沪深两市上市公司的研究,我们发现,相对较小的客户(相对于其审计师事务所的其他客户)被出具非标准审计意见的概率较高。审计师事务所对小客户出具非标准审计意见的倾向性,可能与诉讼成本和非诉讼成本的权衡有关。给定会计准则的偏离事项,审计师对大客户出具审计意见,预期的非诉讼成本(如果出具非标准审计意见)可能高于预期的诉讼成本(如果出具标准无保留意见),因此理性的审计师倾向于出具标准无保留意见;审计师对小客户出具审计意见,预期的非诉讼成本(如果出具非标准审计意见)可能低于预期的诉讼成本(如果出具标准无保留意见),因此理性的审计师倾向于出具非标准审计意见。诉讼成本和非诉讼成本的权衡,导致相对较小的客户更容易招致审计师的不利审计意见。     

审计意见影响因素分析与研究

为了研究上市公司财务状况对注册会计师出具审计意见类型的影响,文章从公司偿债能力、盈利能力和营运能力三个方面的财务指标出发,研究分析了财务状况与审计意见类型之间的相关性.研究结果表明:偿债能力与非标准无保留审计意见的相关性不显著;盈利能力越好的公司被出具非标准意见的可能性就越小;应收账款周转率与应收账款周转天数与非标准审计意见显著负相关;固定资产周转率与非标准审计意见没有显著的相关性.     

本地审计师的合谋效应

本文结合公司的信息不对称程度,从审计收费与审计质量的角度来研究本地审计师的合谋效应问题。研究结果表明,异常审计收费降低了本地审计师对信息不对称程度高的盈余管理公司出具非标审计意见的概率,而并不会降低本地审计师对信息不对称程度低的盈余管理公司出具非标审计意见的概率,同时,异常审计收费也不影响外地审计师出具非标审计意见的概率,表明本地审计师与信息不对称程度高的盈余管理公司之间存在合谋行为;进一步研究表明,信息不对称程度高的盈余管理公司更可能选择本地审计师进行审计,从而为本地审计师的合谋效应提供了进一步的证据。     

企业集团审计师变更与审计意见购买

审计意见购买是学术界和监管部门都十分关注的话题,但以往研究多以单个上市公司为对象来研究审计师变更和审计意见购买,且国内外的经验研究一直未得到一致的结论。考虑到在新兴市场国家,企业集团是主要的企业组织形式,本文以企业集团作为一个整体进行研究,发现审计师对集团内任何一家上市公司出具非标准审计意见,可能导致集团内多家上市公司变更该事务所的审计业务;企业集团通过变更事务所能够实现审计意见改善。此外,变更对象不同,变更后果也不同,首次审计该集团业务的审计师更容易屈服于集团,更容易被收买。     

财务报表异常特征、审计师疑虑与信息使用者保护——基于我国资本市场的经验挖掘

随着资本市场的发展,审计意见越来越成为投资者、债权人和其他利益相关者进行决策的重要依据。然而资本市场上诸多虚假财务报表的出现,不禁令信息使用者对审计质量产生了怀疑。本文使用关联规则分析方法对我国资本市场上9个行业进行了研究,归纳出2003—2005年间被出具非标准审计意见的上市公司财务报表具有的业绩不实、实质与形式不符和资金去向不明等容易引发审计师初步疑虑的异常特征,同时发现具备这些异常特征但被出具了非标准审计意见的样本数仅占35%。     

环境不确定性与审计意见:基于股权结构的考察

本文从公司股权结构的角度,研究企业环境不确定性与审计意见之间的关系。发现环境不确定性所带来的风险,促使审计师出具更多的非标审计意见以降低可能的损失赔偿;由于政府的支持,环境不确定性对国有企业的影响较小,审计师因而对国有企业环境不确定性出具非标审计意见的概率相对要低;进一步的研究发现,审计师对环境不确定性增加了收费,然而,国有控股公司因环境不确定性而增加的审计收费幅度相对较低。     

成本费用粘性对审计师行为的影响研究

成本费用粘性影响企业生存发展，而目前关于成本费用粘性的研究大多探讨其前置影响因素，对成本费用粘性经济后果关注较少。以2012-2021年沪深两市A股非金融上市公司为研究样本，本文检验成本费用粘性对审计师行为的影响。研究表明，成本费用粘性显著增加了审计师对被审计单位的审计收费，并且增强了审计师的谨慎性，审计师更加倾向于出具非标准审计意见。经过更换样本检验、自变量滞后一期检验、工具变量检验以及Heckman两阶段检验，结果保持稳健。进一步研究发现，较高的行业竞争程度和较低的内部控制质量，增强了成本费用粘性与审计师行为之间的显著关系。研究结论拓展了成本费用粘性经济后果的文献，填补了成本费用粘性与审计师行为关系的研究空缺，对审计监管部门规范引导审计市场发展、上市公司完善成本管理以及审计师优化审计程序提供了借鉴。     

监管政策、审计师变更与后任审计师谨慎性

本文以我国2001～2002年出台的相关审计监管政策为例,讨论审计监管对审计师变更和后任审计师谨慎性的影响。由于证监会2001年发布的《公开发行证券的公司信息披露编报规则第14号—非标准无保留审计意见及其涉及事项的处理》(以下简称14号文)增强了非标审计意见之于上市公司的不利后果,因此可能推动了机会主义审计师变更的增加。我们发现,在14号文出台后,前期非标审计意见同审计师变更的正相关关系变得更为紧密,且大所向小所的审计师变更频率显著上升。但是,没有证据表明,相比于未变更公司而言,变更公司的后续审计意见改善程度更高。并且,在2000～2002年,后任审计师针对变更公司的谨慎性有逐渐增强的趋势,这意味着2002年中注协关于审计师变更的监管政策可能发挥了一定的积极作用。     

Costs Associated With Going-Concern-Modified Audit Opinions: An Analysis of the Australian Audit Market

This article examines the potential costs to Australian auditors and their clients from the issuance of first-time going-concern-modified audit opinions. We examine the population of Australian companies receiving a first-time going-concern-modified audit opinion during the period 1994–97 and a matched sample of financially distressed firms receiving a clean audit opinion. Results indicate that auditor switching is positively associated with receipt of a going-concern-modified opinion. However, we find no empirical evidence that there is a self-fulfilling prophecy of increased probability of company failure following the issuance of a going-concern-modified opinion for the Australian companies in our study. Our analyses of lost audit fees indicate that auditors issuing first-time going-concern-modified audit opinions lost proportionately more fees by losing clients (through switching or company failure) than firms not issuing a going-concern-modified opinion to financially stressed clients.     

审计意见的决定因素：来自中国上市公司的证据

利用中国上市公司和相应会计师事务所2001—2003年的综列数据,本文研究了审计意见和会计师事务所规模、上市公司的风险和盈余管理等因素之间的关系。本文发现有破产风险的、进行盈余管理的或小规模的上市公司更可能得到非标准审计意见。如果它们又是大会计师事务所的客户,则得到非标意见的概率更大。本文不支持合资会计师事务所的审计质量更高的结论。     

Audit Firm Tenure and Audit Quality in a Constrained Market

We examine the relation between audit quality and audit firm tenure in the Iranian audit market, which is constrained by government policies that create intense competition for clients among many small audit firms. We develop arguments that these circumstances create cost pressures that entrench low audit quality and render auditors' plans more predictable to managers wishing to misstate their accounts. Using publicly available data for the audits of listed companies in Iran prior to mandatory audit firm rotation and the incidence of misstated financial reports identified by the Iranian Association of Certified Public Accountants Inspection Office, we find that the likelihood of a misstatement is lowest in the first two years of audit firm tenure. We also find that the likelihood of misstatement is not associated with the year preceding a mandatory audit firm rotation, suggesting outgoing auditor effort is not sensitive to the prospect of subsequent revelations of deficiencies. Although our results from a pre-mandatory rotation period show that frequent rotations appear to improve the financial reporting quality in our sample, we are wary of interpreting these results as support for the mandatory audit firm rotation policy in Iran. Rather, we suggest this is a peculiar consequence of deficiencies in audit quality inherent in the Iranian market.     

财务报表重述公司审计质量研究

以财务报表重述公司为研究对象,考察财务报表重述公司年报审计质量。结果表明:财务报表重述的幅度对非标审计意见的出具有显著的影响力;初始差错年和报表重述年,注册会计师都能在一定程度上识别上市公司的盈余管理动机,并在审计意见中有所反映;审计师任期和对财务报表重述公司出具非标审计意见之间没有显著的相关性;事务所规模和非标审计意见的相关性并不显著,结论没有支持大事务所更有可能对重述公司出具非标审计意见。     

Client Importance and Audit Quality at the Individual Audit Partner,Office, and Firm Levels

We investigate whether audit partner level data provides a more powerful measure than office or firm level measures of client importance. We find that the likelihood of issuing a going-concern opinion (any and first-time) increases, and the absolute value of discretionary accruals decreases, in relation to the proportion of audit fees to the total audit fees received by audit partners from all their clients. We also find that the likelihood of issuing a going-concern opinion (any and first-time) increases, and the absolute value of discretionary accruals decreases, in relation to the proportion of non-audit services fees from a client to total non-audit service fees, and the proportion of total audit and non-audit service fees from a client to total fees from all their clients at the office and firm levels. Our findings provide evidence to regulators, audit clients, and stakeholders that audit partners do not succumb to pressure from economically more important clients as audit quality has a positive association with client importance.     

会计师事务所合并与审计收费

以中国2005年以来发生的14起会计师事务所合并案为例,通过大样本的经验研究方法探讨了会计师事务所的合并对审计收费的影响。研究发现,总体来看,会计师事务所合并后审计收费有显著提高;但分组研究发现,只在小客户市场上,会计师事务所合并后审计收费有了显著的提高。进一步的研究发现,在大客户市场上,之所以事务所合并对审计收费的影响无显著的影响,是因为会计师事务所在合并后尽管议价能力有了较大的提升,但同时规模效率也得到了充分的发挥。     

Audit opinion and earnings management: Evidence from Greece

This study examines the relationship between audit opinions and earnings management, as measured by discretionary accruals, for listed firms on the Athens Stock Exchange (ASE). We divide the qualified audit opinions into two categories: qualified for the going-concern uncertainty and qualified for other reasons. The results indicate that audit opinions are not related to earnings management. Client financial characteristics, such as profitability and size are determinants of the going-concern audit opinion decision. The decision of auditors to issue qualified opinions for other reasons is explained by the type of audit opinion issued in the previous year.     

How audit effort affects audit quality: An audit process and audit output perspective

Using a unique dataset of audit days in China from 2006 to 2011, this paper examines the relationship between audit effort and audit quality from the perspective of audit process and audit output. The results show that audit effort significantly increases the probability of audit adjustments, which inhibits positive earnings management and improves the quality of audited financial statements. We also find that audit effort does not have a significant effect on the issuance of modified audit opinions overall, but that a modified audit opinion is more likely to be issued in the absence of an audit adjustment. Furthermore, we find that the impact of audit effort on audit quality is attenuated when clients are more complex and when audit firms are larger. Collectively, our evidence suggests that audit effort plays an important role in improving audit quality by influencing audit process and audit output. Our study extends the literature on the impact of audit effort on audit quality in emerging markets, and the conclusions have important implications for the improvement of China’s audit market efficiency.
