The effect of ownership concentration on firm value has been done by five variables as ownership concentration criteria. Moreover, Tobin's Q has been used to evaluate firms' value. The statistical sample includes 28 companies during 2008-2012 which have been working in the industrial field of pharmaceutical materials. The statistical model of multivariate linear regression is used in this research, and for analyzing statistical data, SAS Version. 9.1 has been applied. <br /><strong>Results: </strong>The results of the research reveal that the variables such as: sum of the share of the main shareholders, natural logarithm of sum of the share of the main shareholders, the main equity capital percentage, sum of the squares of the share percentage of the main shareholders, natural logarithm of the main equity capital percentage as the standards of ownership concentration as well as the variables of reality and legality of the main shareholders, and the degree of control have no effect on firm value. <br /><strong>Conclusion:</strong> In general, the interpretation of the findings of the research suggest that there is no meaningful relationship between ownership concentration and firm value statistically. Besides, type of the main shareholder and the degree of control do not have any influence on firm value. |
