Evaluating Technical Efficiency of Turkish Sugar Production in Pre and Post Privatization Periods

Öz:
The sugar production sector of Turkey has undergone a large-scale privatization in 2018. Since then, 10 out of 33 sugar factories have been privatized. The objective of this research is to investigate the effects of the privatization on the technical efficiency of the sugar factories. For this purpose, the data of 31 factories operating in different parts of the country are utilized. We evaluate the efficiency before and after privatization in two periods: pre-privatization (September 2017 - August 2018) and after-privatization (August 2018 - September 2019) using Data Envelopment Analysis, Malmquist Productivity Index and DEA by Sequential Exclusion of Alternatives methods. First, while results derived from all models reveal a technical efficiency decline among factories in general, the privatized factories stand out as the only subset that experience an increase in technical efficiency for the period analysed. Secondly, the benchmarks for the inefficient factories are identified in the short term and the long term using ‘DEA by Sequential Exclusion of Alternatives’ to assist improvement decisions. Finally, the research presents some methodological insights on the application of the ‘DEA by Sequential Exclusion of Alternatives’ approach by experimenting with changing parameters that have the potential to aid future applications.

Türk Şeker Üretiminin Özelleştirme Öncesi ve Sonrası Teknik Etkinliğinin Değerlendirilmesi

Öz:
2018 yılında Türk şeker sanayisi büyük ölçekli bir özelleştirmeyi tecrübe etmiştir. O yıl, 33 şeker fabrikasından 10 adeti özelleştirilmiştir. Bu araştırmanın amacı, bu özelleştirmelerin fabrikaların Teknik etkinliğine olan etkisini gözlemlemektir. Bu amaçla ülkenin çeşitli bölgelerinde yer alan 31 adet fabrikanın verisi kullanılmaktadır. Teknik etkinlik, Veri Zarflama Analizi (VZA), Malmquist Verimlilik Endeksi ile Alternatiflerin sıralı hariç tutulmasına dayalı VZA yöntemleri kullanılarak iki dönem için değerlendirilmektedir: özelleştirme öncesi (Eylül 2017 - Ağustos 2018) ve özelleştirme sonrası (Ağustos 2018 - Eylül 2019). Sonuçlar, öncelikle, analiz edilen dönemler arasında genel anlamda bir etkinlik düşüşüne işaret etmektedir. Bununla beraber, özelleşen fabrikalar etkinlikte artış gösteren tek alt küme olmaktadır. Araştırma, etkin olmayan fabrikalar için alternatiflerin sıralı hariç tutulmasına dayalı VZA kullanılarak elde edilen referans kümelerini de sunmaktadır. Çalışma ayrıca bu metodun gelecek uygulamalarına bir kavrayış sağlama amacına yönelik parametre değerlerinin değiştirilmesine dayanan testler de içermektedir.
