The aim of this research is to study the impact of specialization, notoriety, recurrence and joint audit on the efficiency of investments as well as the impact of the moderating effect of the auditor’s criteria. This study examines the relationship between investment efficiency and audit quality, using a representative sample for the period 2012-2018. In addition, in order to show the relationship between the auditor's criteria this paper uses the moderating effect of the different criteria. i.e., whether such an auditor’s criteria effect on investment efficiency is increasing or decreasing with the presence of other criteria. The reached result reveals that the auditor's criteria have a moderating effect on the relationship between audit quality and investment efficiency. Indeed, the presence of two audit criteria makes it possible to improve the investment efficiency. Similarly, there is a causal relationship between the different audit criteria; the presence of an audit criterion makes it possible to have the other criteria.
