Natural gas should be distributed and consumed optimally in a given country since it is an important intermediate good for producers and a necessary final good for households with a low-income elasticity. Thus, this study aims to measure the efficiency of natural gas distribution companies responsible for delivering natural gas to economic units. The efficiency of 63 natural gas distribution companies operating in Turkey is estimated by the Stochastic Frontier Analysis method for 2013-2018. According to the findings, it is found that no firm operates within full efficiency. It is also concluded that while Bursa Natural Gas Distribution firm has the highest efficiency, Aksa Çanakkale Natural Gas Distribution firm has the lowest efficiency for the period studied. The findings show that inefficiency mainly stems from technical inefficiency rather than measurement errors and that natural gas distribution firms experience increasing returns to scale.

Türkiye Doğal Gaz Dağıtım Firmalarının Etkinliğinin Stokastik Sınır Analiziyle Ölçülmesi

Öz

Gelir esnekliği düşük, firmalar için ara mal, hane halkları için nihai mal durumundaki doğal gazın ülke içinde dağıtımının ve kullanımının optimal gerçekleştirilmesi gerekmektedir. Bu gereklilikten hareketle, ilgili ekonomik birimlere doğal gazın ulaştırılmasında sorumluluğu üstlenen dağıtım firmalarının ne kadar etkin (ya da etkinsiz) çalıştığını ölçmek, bu çalışmanın amacını oluşturmaktadır. Bu amaç çerçevesinde, 2013-2018 yıllarını içeren dönemde Türkiye içinde faaliyet gösteren 63 doğal gaz dağıtım firmasının etkinliği Stokastik Sınır Analizi (SFA) yöntemiyle ölçülmektedir. Analiz sonuçlarına göre; hiçbir firmanın tam etkinlikte çalışamadığı, Bursa Şehir İçi Doğal Gaz Dağıtım firmasının en yüksek etkinliğe, Aksa Çanakkale Doğal Gaz Dağıtım firmasının ise en düşük etkinliğe sahip olduğu sonucuna ulaşılmaktadır. Bulgular; etkinsizliğin, ölçüm hatalarından çok, teknik etkinsizlikten kaynaklandığını ve firmaların ölçeğe göre artan getiride çalıştıklarını göstermektedir.
