Abstract: 

Through Employing Bootstrap Data Envelopment Analysis and LSW Algorithm this study aimed at estimating bias corrected efficiency, technical efficiency, managerial and scale efficiencies for firms with 10 or more labor forces during the year 2011. Bootstrap is a resampling technique applied to estimate the distribution properties of an estimator. Such methods are used when dependency and sensitivity of ranking and efficiency values of each economical firm changes in sample compositions and also when it is necessary to correct generated bias caused by calculation of efficiency values in conventional methods of input-data envelopment analysis. The results showed that the average of managerial and scale efficiencies of our country’s industry section are 77% and 94% respectively. This shows that the main reason for technical inefficiency is inefficient management.9% of our country’s industry sector, functions with complete technical efficiency, and 48% of the sector functions with less than 70% of technical efficiency.
