The current research is descriptive and in terms of its practical purpose and the method used in this research, it is a survey of the correlation type using historical information retrospectively; That is, it is done using past information and using multivariate regression and econometric models. The statistical population of the research is all the companies admitted to the Tehran Stock Exchange in the period of 1401-1397, and 141 companies were analyzed as the final sample of the research. The collected data of the companies were analyzed using regression analysis and using Eviews and Stata software. The results of regression analysis and hypothesis testing show that there is a positive and significant relationship between family ownership and profit management, and there is an inverse and significant relationship between financial leverage and profit management. Also, the results of the model analysis show that financial leverage has a moderating role in the relationship between family ownership and profit management. In other words, it can be said that as the financial leverage increases (decreases) in the company, the amount of family ownership and profit management in the company decreases (increases) in the reverse direction.
