Özet:

Purpose: This study aims to investigate the performance of Turkey’s electricity distribution companies added the privatization program from the point of efficiency and productivity.  Methodology: Efficiency and productivity analyses were condutcted using Data Envelopment Analysis and Malmquist Total Factor Productivity Index. For the measurement of efficiency, the input-oriented CCR model, which considers the constant return to scale, and the input-oriented BCC models, which consider the variable return to scale, have been tried. The change in total factor productivity and the sources of this change in the related period were explained by Malmquist Total Factor Productivity Index. Findings: Efficiency has its lowest level in 2013 and highest level in 2016. The greatest increase in total factor productivity occurred in 2013-2014, and greatest decrease occurred in the period of 2014-2015. The average increase in total factor productivity of the sector as a whole is 10,5% annualy. The results of the study indicate that the decision units work inefficiently and that the differences in the welfare level of the regions served by the distribution companies do not have a significant effect on the efficiency. Originality: In the study both efficiency and productivity of the electricity distribution companies are examined for the period 2012-2018. Due to the importance of the energy sector this subject is worth investigating. For these reasons, the study has originality.
