The results are consistent with other works carried out in our country, and they point to the absence of size effect on the economic profitabilit, that suggets the convenience of analyzing other specific factors of the firm that will be anle to explain better the disparities fo profitabilities interfirms. However, we have been able to verify that the industry explains a part of the variability observed in the profitability, althought wa cannot observe any relation between size and activity sector.
