Explaining the relationship between the audit quality and the company's operational efficiency by considering the criterion of the auditor's tenure in the industry and the size of the auditor

The present study explains the relationship between the audit quality and the company's operational efficiency, taking into account the criterion of the auditor's tenure in the industry and the size of the auditor for 108 companies active in the stock exchange during the period from 2011 to 2020 and using the static panel model. According to the estimation results of the model; Subsections of audit quality features include; The size of the auditor and the continuity of the auditor's tenure are significant on the operational efficiency of listed companies, in other words, if the size of the auditor increases by one unit, the operational efficiency of the companies increases by 10 units, and if the continuity of the auditor's tenure as an indicator of the audit quality of a unit increases, the operational efficiency increases. Companies increase by 4 units. According to the results of this research, it can be predicted that the continuity of tenure of auditors and audit institutions with larger size (such as audit organization) compared to other institutions, increases the reliability of accrual items of commercial units. Therefore, it can be recommended to the general assemblies of the companies to use larger audit institutions for the audit of their company. Information that is an inseparable part of the decision-making process, the more transparent and accessible it is, it can lead to more correct decisions in the field of optimal allocation of resources.
