Providing voluntary financial information about identifying, measuring and disclosing accounting items in the financial statements as well as non-financial information attracts investors and contributes effectively to improving the financial position, management face and sustainability of the company. However, executives of insufficient companies may manipulate their financial information to conceal or delay an inappropriate financial situation. Therefore, managers of non-financial corporations are more likely to have a lack of transparency and to avoid disclosing supplementary and voluntary information. In this regard, the present study examined the role of corporate power in voluntary disclosure of non-financial information and corporate sustainability performance. The statistical population of this study included all companies listed in Tehran Stock Exchange from 2008 to 2017 and the sample was selected through systematic elimination from the statistical population. According to the specified conditions, 112 companies were selected as the statistical sample of this study. It is worth noting that the hypotheses were tested by designing multivariate regression models. The results showed that firm strength enhances the direct relationship between voluntary disclosure of non-financial information and its dimensions with firm sustainability performance.
