İşletmelerin Finansal Performansının Veri Zarflama Analizi Yöntemiyle Tespit Edilmesi: Borsa İstanbul’da İşlem Gören Enerji İşletmelerine Yönelik Bir Uygulama

Abstract

One of the important factors in the realization of economic and social development is energy. Especially in recent years due to rapid population growth and industrialization, the need for energy has gradually increased. However, due to globalization, competition between enterprises has become increasingly brutal. In order to survive and achieve a satisfactory profit margin in a globally competitive environment, businesses need to use resources effectively, achieve maximum output with minimum input, and effectively control costs by minimizing costs. In this respect, efficiency analysis to be conducted in enterprises is important both in evaluating the performance of enterprises and determining their position in the global competition environment. The purpose of this study is to measure financial performance and efficiency of energy businesses listed on Borsa Istanbul (BIST) in 2019 by using Data Envelopment Analysis (DEA). For this purpose, the efficiency of 8 businesses with the output-oriented Charnes-Cooper-Rhodes (CCR) model of DEA method was measured by using 2 input and 4 output factors obtained from financial statements. As a result of the study, 5 businesses operating in the energy market were found to be effective. Finally, the businesses that should be referenced in order to increase the efficiency levels of ineffective businesses were identified and the necessary potential improvement rates related to input and output variables were determined.
