Auditing quality has special importance for financial statement’s users, managers, and auditors. The aim of this study is to model the relationship among auditing quality factors and investigating the effect of mutual relationship among its related variables. For this purpose, 101 firms listed in Tehran Stock Exchange (TSE) were selected for a period of 11 years (2004 to 2015). The research method is based on the cause and effect model in system dynamics. The data was collected using financial statements and Rahavard Novin databases. The test of normality, unit root test, correlation and hypothesis testing (multiple regression, partial regression, ARCH functions as required) was applied by SPSS version 23 and Eviews version 9. The results showed that Standards Compliance and Professionalism, Audit Fees, Auditor firm Size, Auditor’s Reputation, Number of Paragraphs in Audit Report, Percentage of misrepresentations and noncompliance, Audit Opinion Type, Delay in the Audit Report, Auditor’s Tenure, and Auditor's Expertise and Industry Knowledge have mutual effects on each other.
