The Relationship between the Added Value of Intellectual Capital, the Efficiency of Human Capital with an Emphasis on Growth and their Effect on the Growth of Per Capita Income of Employees in Companies Listed on the Tehran Stock Exchange

The purpose of the present study is to investigate the relationship between the added value of intellectual capital, the efficiency of human capital, with an emphasis on growth and their effect on the growth of export income per capita of employees in companies listed on the Tehran Stock Exchange. The export performance of companies is influenced by various internal and external factors. Some of the internal factors include knowledge of target markets and presence in international production networks, which are among the knowledge capital of companies. The current research is applied in terms of purpose and descriptive-correlational in terms of nature and method. In order to calculate the intellectual capital, the coefficient of added value of the intellectual capital has been used, and to calculate the export, the ratio of export sales to the total sales of the company has been used. Hypotheses have been tested using linear regression. The statistical population is all the companies admitted to the Tehran Stock Exchange. A statistical sample of 178 companies was selected between 2016 and 2020. The results show that there is a positive relationship between intellectual capital, human capital efficiency and export income. Also, there is a positive relationship between the growth of human capital and the growth of export earnings. However, contrary to the initial expectation, no evidence was found that the growth of intellectual capital is effective on the growth of export income. Therefore, necessary measures should be taken through ways such as proper corporate governance, timely and proper policy making. It is suggested that the accounting standards give a special role and importance to intellectual capital (as a factor influencing the added value of the company).
