This study examines the impact of capital structure and ownership structure on the survival of companies. The ownership structure includes two types of ownership: major structure and institutional ownership. The statistical population consists of 484 companies listed in Tehran Stock Market for the period 2004-2014; eventually, through a systematic elimination method, our samples includes 234 companies. In this research, the logistic regression model and Eviews-9 software are used to analyze the data and test the hypotheses. The results of the research show that there is a negative and significant relationship between capital structure and company survival. In addition, major ownership has a negative effect on the survival of companies in the stock market. Moreover, the results indicate the positive and direct impact of institutional ownership on the survival of the companies.
