Abstract

 
Considering the role of banks in Iran and the significance of appraising their functions, this study evaluates the banks' efficiency during 2010-2014. There are many researches in field of bank's efficiency and productivity with DEA but all of them do not consider their internal structure in surveying of efficiency. Main aim of this paper is to survey efficiency of 18 banks with Network Data Envelopment Analysis (NDEA). In this paper, worker, fixed asset and official and public costs are interred to model as input, bank deposit is intermediate variable ( output in first step and input in second step), banks profit is desirable output and Non-performing loans of banks is undesirable output which are considered in model. Variables are interred to model according to their roles in bank's structures. Results reveal that else of 3 banks, all banks of our sample operated less than efficient level in our period. Performance of some banks is so weak and some banks which have more Non Performing loans have lower efficiency.
