Measuring the Efficiency of Companies in BIST Sustainability Index: An Application With Data Envelopment Analysis

Summary/Abstract: In the increasing competition environment, companies have to keep their inputs at a minimum to reach the output they want to achieve. Achieving maximum output with minimum inputs also ensures continuity of companies by increasing efficiency, productivity, effectiveness and profitability of the enterprises. In this study, efficiencies of the companies that are traded in the BIST Sustainability Index for the years 2015 and 2016 were determined by Data Envelopment Analysis. Lack of studies evaluating the efficiency of the company in sustainability trends in Turkey shows the importance of this work. Efficiency values were using the input obtained BCC model. In the study, equity, total debt and total assets were used as input variables and net profit, asset profit rate and equity profit rate were used as output variables. The study showed that 10 companies were efficient in 2015 and 7 companies were efficient in 2016. The number of companies that are efficient in both years is 5. Potential improvement rates for inactive firms in the study were also determined. According to these rates, inefficient Decision Making Units need to reduce input variables by an average of 37.1% in order to be efficient.
