Corporate governance is considered as a set of internal and external control mechanisms that are responsible for establishing an appropriate balance between the rights of shareholders on the one hand and the needs and powers of the board of directors on the other, and is a suitable solution to solve agency problems that may arise from conflicts of interest between managers and shareholders or stakeholders. The present study is applied in terms of its implementation results and is correlational in terms of methodology and causal (post-event) in terms of the time of the research. The sample of the present study includes 119 companies listed on the Tehran Stock Exchange for the years 2018 to 2024. Multivariate regression with composite data was used to test the research hypotheses. The results of the hypothesis test showed that institutional ownership has a negative effect on management short-sightedness, but ownership concentration has a positive effect on management short-sightedness. Also, the independence of the board of directors has no effect on management short-sightedness.
