事务所规模、审计行业专长与知情交易概率

外部审计的作用在于提高公司的信息披露透明度,减少信息不对称,以保护投资者利益。本文从知情交易概率视角出发,研究了外部审计在减少信息不对称方面所发挥的作用。研究结果发现,国内"十大"审计的公司,以及由具有审计行业专长的事务所审计的公司,知情交易概率更低,而且行业专长的国内十大(非十大)审计的公司的知情交易概率也低于不具有行业专长的国内十大(非十大)。进一步检验还表明,在机构投资者持股的公司中,事务所规模和审计行业专长能够更有效减少知情交易概率。     

审计师子群体地位与审计质量

本文在中国文化背景下考察审计师子群体地位对审计质量的影响,并在此基础上研究积极的直接接触对群体地位与审计质量关系的调节作用。基于1990-2016年50起会计师事务所合并事件,我们识别出53个事务所分所中存在的106个审计师子群体。在此基础上,我们发现,相对于高地位审计师子群体,合并后低地位审计师子群体客户盈余管理水平显著提高。此外,我们还发现,当分所内审计师子群体间有积极的直接接触时,相对于高地位审计师子群体,合并后低地位审计师子群体客户盈余管理水平提高的幅度减弱。这些研究结果表明,分所内低地位审计师子群体保持或者提高其在分所内的地位,维护其自身利益的动机更强,则其发生机会主义行为的可能性越大,其审计质量随之变差;而积极的直接接触则可以有效改善群际关系,缓解审计师子群体地位对审计质量不利影响。     

监管风险、事务所规模与审计质量

我国会计师事务所规模与审计质量之间是否存在正相关关系,现有研究一直存在争议。本文从注册会计师的执业环境出发,对此进行了重新审视。用上市公司实际控制人的控制权与现金流权之差衡量事务所面临的监管风险,研究发现,大事务所只对监管风险较高的客户提供高质量的审计服务。进一步的研究表明,事务所面临的监管环境改善后,大事务所才对所有客户提供高质量的审计服务,审计质量与事务所规模之间的正相关关系不再依赖监管风险而存在。因此,在法律环境相对薄弱的情况下,加强监管是促使会计师事务所提供高质量审计服务的有效机制。     

审计师变更与审计质量:一个理论分析

本文通过建立股东、管理层和审计师三方参与的两委托人-单代理人博弈模型,研究了固定审计费用下不同审计师变更方式对审计质量的影响。研究结果表明,审计师强制性单期变更与审计师强制性定期变更下,审计师与管理层之间的合谋将导致严重的财务舞弊;而在审计师自愿性变更下,股东可以利用解聘现任审计师这一威胁来阻止审计师和管理层之间的合谋,使得审计师和管理层的最优策略均为真实披露公司的盈余信息,并发表标准无保留审计意见。     

审计师变更与审计质量：一个经验研究综述

本文对国内外有关审计师变更与审计质量的经验文献做了较为全面、系统的回顾。总的看来,已有的文献主要从审计师变更与审计意见购买、审计任期与盈余质量以及审计师变更与盈余质量三个方面来考察审计师变更对审计质量的影响,但并未取得一致性的研究结论。本文在对相关文献综述的基础上从多维度计量盈余质量和结合中国特殊的制度背景两个方面提出未来的研究方向。     

Does Opinion Shopping Impair Auditor Independence and Audit Quality?

This study investigates how companies' threats to dismiss auditors and their engagement in opinion shopping influence auditor independence and audit quality, which in turn affect misstatements in financial statements. It also examines how outsiders' reactions to auditor switching influence opinion shopping. The results indicate that neither the predecessor auditor's nor the successor auditor's independence is compromised by dismissal threats and opinion shopping. Further, the successor auditor's audit quality exceeds the predecessor auditor's audit quality. In addition, auditor switching decreases potential understatements and increases potential overstatements in financial statements, and the capital market's and the successor auditor's reactions to auditor switching reduce the benefits of opinion shopping to companies. Additionally, the study sheds some light on the potential effects of both the Sarbanes‐Oxley's restriction on non‐audit services and mandatory auditor rotation or retention. The paper also derives a rich set of empirical implications.     

审计师规模与审计质量:声誉视角

本文基于2010年至2013年的四个公司舞弊事件,考察了声誉受损后的审计师变更情况,发现:市场并没有用"及时离开"来惩罚声誉受损的审计师,使其失去准租,审计师的执业资格直接决定了其能否继续获取准租。我们的讨论,是对De Angelo(1981b)审计师规模与审计质量的补充与修正,将有助于更好地理解审计师规模与审计质量之间的传导机制,丰富规模与质量的理论体系。     

会计师事务所行业专长与审计质量相关性的检验——来自中国上市公司审计市场的经验证据

行业专长是审计师专业技能的重要构成要素之一。国外大量的研究均证实会计师事务所的行业专长能够提高审计质量,而本文的研究却发现,在中国上市公司审计市场中,就总体而言,会计师事务所行业专长与审计质量负相关。进一步的分析则表明,目前我国会计师事务所总体上独立性相对不高、易受行业内经济依赖度的负面影响和行业专长发展程度较低是造成这种负相关性的主要原因。     

Non-audit Service Fees and Audit Quality: The Impact of Auditor Specialization

We posit that the effect of non‐audit fees on audit quality is conditional on auditor industry specialization. Industry specialist auditors are more likely than nonspecialists to be concerned about reputation losses and litigation exposure, and to benefit from knowledge spillovers from the provision of non‐audit services. We find evidence that audit quality measured by increased propensity to issue going‐concern opinion, increased propensity to miss analysts' forecasts, as well as higher earnings‐response coefficients increases with the level of non‐audit services acquired from industry specialist auditors compared to nonspecialist auditors.     

Audit Committee Effectiveness and Financial Reporting Quality: Implications for Auditor Independence

Auditors participating in a survey identified oversight of financial reporting and the external audit process, and ensuring quality internal controls, as the most important functions of effective audit committees. Financial literacy or expertise, independence, and a strong commitment to perform the job effectively were noted as important attributes. The results also suggest that although audit committees have enough power to confront management on contentious issues, they are not very effective in helping to resolve financial reporting disputes. Management was identified as a key influence in affecting the nature, extent, and quality of communication between the auditor and the audit committee. Most auditors believe that it is not important for each member of the audit committee to be an expert, but it is important that they are financially literate.     

Audit Firm Tenure,Non‐Audit Services,and Internal Assessments of Audit Quality

We use data from internal assessments of audit quality in a Big 4 firm to investigate the impact of audit firm tenure and auditor‐provided non‐audit services (NAS) on audit quality. We find that first‐year audits receive lower assessments of audit quality and that quality improves shortly thereafter and then declines as tenure becomes very long. Partitioning our sample between SEC registrants and private clients, we find that the decline in audit quality in the long tenure range is attributable to audits of private clients. For audits of SEC registrants, the probability of a high quality audit reaches its maximum with very long tenure. We also find that audit fees are discounted for first‐year audits but auditor effort is higher than in subsequent years. We find no association, on average, between total NAS fees and audit quality in the full sample but observe that total NAS fees are positively associated with quality for SEC registrants and negatively associated with quality for privately held clients. Our findings are important for regulatory policies related to audit firm tenure and auditor‐provided NAS.     

会计事务所组织形式、法律责任与审计质量——基于签字审计师个体层面的研究

本文从签字审计师个体层面研究了会计事务所组织形式对审计质量的影响。与有限责任制相比,特殊普通合伙制将审计法律责任与风险落实到了签字审计师个人,增加了审计师的违规成本,因此审计师可能会变得更加独立和谨慎。研究表明,同一签字审计师同年在特殊普通合伙制身份下比在有限责任制身份下更容易出具非标审计意见,其审计公司的盈余管理水平更低,审计质量更高。同时,我们还发现,事务所从有限责任制转变为特殊普通合伙制以后,相同签字审计师转制后出具非标审计意见的可能性更高,而且被审计公司的盈余管理水平更低,审计质量也明显提高。这些结果为我们判断2010年以来我国推动事务所转制为特殊普通合伙制的政策提供了直接的经验证据,表明特殊普通合伙制对审计师的审计行为产生了预期的政策治理效果,有助于事务所做强。     

Audit Quality and Auditor Size: An Evaluation of Reputation and Deep Pockets Hypotheses

Empirical studies have shown that large auditors are more accurate than small auditors. The reputation hypothesis states that large auditors have more incentive to be accurate because an inaccurate report may lead to a loss of client-specific rents (DeAngelo, 1981). The deep pockets hypothesis states that large auditors should be more accurate because they have greater wealth at risk from litigation (Dye, 1993). This paper presents evidence on the relationship between auditor size and litigation and on the market shares of criticised and uncriticised auditors – the findings give greater support to the deep pockets hypothesis than the reputation hypothesis.     

审计任期与审计质量:来自中国证券市场的经验证据

本文以中国证券市场上2000年至2002年期间获得标准无保留审计意见的上市公司为样本,使用经过一定调整后的截面Jones模型估计出的公司操纵性应计利润的绝对值作为审计质量的衡量指标,考察了会计师事务所审计任期与审计质量之间的关系。研究发现,在控制了事务所变更、事务所特征、行业成长性、公司规模、经营业绩、资产负债率、上市年龄以及样本所在年度后,审计任期与公司操纵性应计利润的绝对值呈正U型关系,即审计任期与审计质量呈倒U型关系。进一步分析发现,当审计任期小于一定年份(约6年)时,审计任期的增加对审计质量具有正面影响,而当审计任期超过一定年份(约6年)时,审计任期的增加对审计质量具有负面影响。     

资源控制权与审计师轮换的治理效应

审计师轮换是构建独立审计秩序化格局以防范会计舞弊的重要监管手段。本文基于会计师事务所内部治理尤其是资源整合的角度研究了审计师轮换对审计质量的影响,结果发现,审计师轮换后,会计师事务所出具非标意见的概率显著上升,高客户资源控制权个人化会计师事务所显著抑制了公司的正向盈余管理水平;高客户资源控制权个人化会计师事务所在审计师轮换后抑制公司正向盈余管理水平的提高幅度大于低客户资源控制权个人化会计师事务所。结果表明,审计师轮换提高了审计独立性和审计质量,有助于实现客户资源控制权个人化向会计师事务所化的转变。     

Auditor Expertise and the Estimation of Dollar Error in Accounts

A major task that auditors undertake in formulating their audit opinion is to estimate the dollar error that might exist in accounts in light of their evaluation of internal control strengths and weaknesses. The research that has been undertaken to evaluate the quality of auditor performance on this task, however, has produced mixed results. The current study tries to overcome some theoretical limitations and measurement limitations that have undermined prior studies. Forty practising auditors rated their abilities on fourteen characteristics derived from a model of expertise. They then undertook an experiment where they judged the extent of dollar error that might exist in the inventories of a manufacturing company. They based their judgments on working papers provided to them that contained, among other information, an evaluation of the company's internal control system. An estimate of the 'true' dollar error in the inventories was calculated using a program that simulated the company's internal control and accounting system. This estimate was then used to calculate the accuracy of the auditors' judgments. Their ratings on the expertise characteristics were not related to their judgment accuracy. Their ratings were related, however, to their confidence in their judgment accuracy. Auditors who considered themselves more expert at the task were more confident in their judgment accuracy but they were, in fact, no more accurate than auditors who considered themselves to be less expert at the task.     

审计市场结构与审计质量:来自中国证券市场的经验证据

本文以我国证券市场2004年~2005年的上市公司为研究样本,使用调整后的KS模型估计出的公司操纵性应计利润的绝对值作为审计质量的衡量指标,考察了审计市场结构和审计质量的关系。研究发现在控制了影响审计质量的相关变量之后,市场结构与审计质量存在以下关系:审计市场集中度与审计质量成正相关关系;市场的进入退出壁垒越高,审计质量越高;但审计师的行业专长不但没有提高审计质量,反而在一定程度上降低了审计质量;审计市场的强地域性与审计质量也没有明显的相关关系。     

审计委员会特征与会计师事务所变更的经验研究

本文以会计师事务所变更为视角,探讨具备怎样特征的审计委员会才能有效履行其职责。研究表明:审计委员会的独立性和专业性与会计师事务所变更显著负相关;审计委员会的开会次数与会计师事务所变更没有显著关系,说明审计委员会的存在有助于减少会计师事务所变更。但在对会计师事务所变更的进一步研究中,我们并没有发现会计师事务所变是为了追求更高审计质量的进一步证据,也说明审计委员会对会计师事务所变更的影响仍然有限。这些研究结论为完善我国审计委员会制度提供了经验证据。     

审计市场供需不平衡、事务所选聘与审计收费

从审计市场供需双维视角,基于2007-2013年沪深两市A股上市公司样本,观察我国省级层面审计市场供需不平衡1对事务所选聘及审计收费的影响。结果表明,当省级审计市场存在供需不平衡时,会计师事务所供给每增加1个标准单位,客户选聘当地事务所的可能性增加1.4%,其中国际"四大"、本土"六大"及其他小所供给每增加1个标准单位,客户选聘当地事务所的可能性增加1.6%、1.2%和2.7%,审计费用将分别增加近2%、降低1.5%和9.9%。论文首次从我国省级层面较好地解释了审计市场供求关系变化对事务所选聘及审计收费的影响,丰富了审计相关理论,也为会计师事务所在不同省域开展业务、监管者评估不同地域间审计市场发展状况提供新的依据。     

The Role of Tacit Knowledge in Auditor Expertise and Human Capital Development

Two critical aspects of the model of auditor expertise development in Tan and Libby [1997] are that audit firms do not value tacit knowledge in inexperienced auditors but do value it in experienced auditors. We update the former and extend the latter. Our paper predicts and finds that audit firms now do value tacit knowledge in inexperienced auditors, especially when their supervisors have higher tacit knowledge. Our proxies of value include higher promotability assessments, annual evaluations, and cash bonuses. Our paper also extends Tan and Libby [1997] by positing that enhanced development of expertise and audit firm human capital are two reasons audit firms value tacit knowledge in experienced auditors. As predicted, higher tacit knowledge in experienced auditors is positively associated with higher tacit knowledge acquisition by their inexperienced subordinates and with stronger firm commitment of inexperienced subordinates having higher tacit knowledge.
