Internal and external factors affect the capital structure, and macroeconomic variables are among these factors. A s an applied research, using a multi variable regression model, the present research seeks to investigate the nature and how the macroeconomic variables influence the capital structure of companies admitted to the Iranian OTC market. For this purpose, a descriptive-analytical method and information related to 53 companies accepted in the Iranian OTC market have been used. Macroeconomic variables in this research include inflation rate, bank interest rate, exchange rate and liquidity volume as independent variables and variables of return on equity, return on total assets, ratio of fixed assets and ratio of dividends paid as control variables.
