| Abstract:
This paper attempts to compare the criteria of performance evaluation and introduce better criterion for considering different aspects than others. Among these criteria, economic value added was introduced to provide value. The purpose of EVA is to measure the increase or elimination of company's value and correct evaluation of performance management. EVA is not a new discovery, but a criterion for evaluating of performance obtained from difference of operational profit after tax and capital expenditure.
The purpose of ROE, as an accounting criterion, is to measure output rate, designed for ordinary stockholders. Another criterion designed and used before these criteria is the rate of output assets (ROA) . Study of correlations between these criteria is useful for some aspects, so that they can be used as an alternative in place of each other.. EVA is a method for measuring the economic value (profitability) of a business after considering total capital expenditure- both liability's expenditure and expenditure of owners’ equity. Often in traditional methods (based on accounting), just the liability indicated in expenditure accounts. In this study, the mentioned variables in period of 81 to 85 in active chemical companies in Tehran stock exchange were calculated and the correlation between these variables in the shape of two theories, by correlation coefficient of Pierson were tested. The result of this study showed that there is no meaningful relationship between criterion of value (EVA) and criterion of accounting (ROE, ROA) .
