This method was performed on a sample of 62 studies, including 42 external studies in the period 2008 to 2019 and 20 internal studies during the years 2007 to 1397. Independent variables of three categories of board of directors (independence and size of the board of directors, duality of the role of chief executive officer) and ownership structure (internal ownership and institutional ownership) were considered and corporate profit management was considered as a dependent variable. The results show. The results of research hypotheses also indicate a significant relationship between corporate governance and profit management.
