In recent decades, most of the theories of the classical corporate era have been revised and new theories such as agency theory have been proposed. Many factors affect the value of a company and so far research has been done to determine the relationship between different financial and accounting variables of companies with their value, but the structure of ownership as one of the variables affecting the value of the company, less attention has been paid. Therefore, based on this argument, the purpose of this study is to investigate the effect of ownership structure on the relationship between equity costs and company value using a sample of 105 companies during the years 2015 to 2020.
