Özet:

Data envelopment analysis is one of the tools that has been used frequently on evaluating the performance of the firms. Particularly in today's competitive conditions, since the firms have been facing many external and/or internal factors closely, data envelopment anaysis (DEA) method is used for measuring inputs and outputs on the relative efficiency of operational processes. When the banking sector is analysed in Republic of Turkey, the degree of competition among the banks has shown that it is necessary for them to use their resources more efficiently. Hence, in terms of financial performance of banks, defining the efficiency limitations would be easier and more efficient with some statistical tools. The purpose of this study is to analyze the performance of all deposit banks in Turkey by using data envelopment anaysis with entropic weights.
