The measurement of efficiency is aimed for stochastic frontier analysis, a parametric method, introduced by Aigner, Lovell and Schmidt 1977 and Meusen and Van Den Broeck 1977 . In the study, two different models were constructed according to the corresponding year of Cobb-Douglas C-D for the data set from ISO 500 firms of the years 20112014. Firm based efficiency measurement was carried out by cross sectional data. Also it was exhausted by branching off sectors according to NACE REV 2 economic operation classification and mean efficiency scores too. In SFA the data values should always be positive. Two different transformation have been carried out to make negative values positive. Although first transformation gives meaningful results statistically, since it isn’t proper financially second transformation was done.
