Abstract

Regarding the studies performed on firm ownership structure, it is perceived that concentrated or diffused ownership can significantly affect the firm’s performance with regard to country’s economic structure. Therefore, in this research, we studied the ownership structure using the three criteria return on asset, return on equity and firm value. The results achieved from hypotheses test performed using combination regression and panel data method (minimum square method) for information of 601 firms listed in Tehran Stock Exchange for the period from 2010 to 2014 suggests that ownership concentration does not show a meaningful relation with return on asset and firm value; however, ownership concentration shows to have a meaningful positive relation with return on equity.
