The statistical population comprises companies listed on the Tehran Stock Exchange, and through systematic elimination sampling, 130 companies were selected as the sample. The study period spans seven years, from 2017 to 2023. Data were collected through a library-based method, and Stata software was employed to test the hypotheses.
