To do it, selected 100 companies of 13 different industries as the statistical sample and by fitting multivariable regression models with table data, have been surveyed for the relationship between investment structure scales and company's profitability during 6-years period (2002-2007) for sample companies.The results of the research show that there is a positive relationship between short-term debt to assets and company's profitability and also between total debts to total assets and profitability.
