A Study on the Efficiency of Turkish Deposit Banks for the Period 2012-2022: DEA Model

The profitability and efficiency of banks are decisive parameters in an intensely competitive industry. The up-to-dateness and remarkable importance of the concepts of efficiency and effectiveness in the banking sector have led to this study. In this study, the efficiency of the Turkish banking sector will be tested with the Data Envelopment Analysis (DEA) method. In the study, data from 24 deposit banks operating in the Turkish banking sector for the period 2012-2022 were used. When the θ efficiency of the banks was evaluated according to the output-side CCR model of 24 banks in the 11 periods included in the analysis, it was determined that 146 of the 264 bank periods were efficient with an efficiency score of 1. It has been observed that 55.3% efficiency has been achieved in 11 periods of 24 banks examined in the last 11 years.
