In the financial literature, risk-taking and investment-related decisions are among the most important decisions for companies that make optimal decisions in these two areas, optimally allocating resources and directing financial resources to economic investments and profitable projects for value creation. The purpose of the research is to investigate the relationship between audit quality and risk taking on value creation in firms listed in Tehran Stock Exchange (TSE). The research used five components of auditor's specialist, tenure, audit size, ownership concentration, and board of director’s independence to evaluate audit quality. The statistical population of the study includes the companies listed in TSE. Using a screening method, ۶۱۰ firm-year data were selected for a ۵-year period (۲۰۱۳-۲۰۱۷). This research is based on panel data and multivariate regression method. The research findings show that among these five components as well as the risk factor, only the variables of auditor tenure and ownership concentration have a significant effect on corporate value creation. The originality of the results of the research contributes to the auditing and capital market in TSE.
