ON DIMENSION REDUCTIONS IN DATA ENVELOPMENT ANALYSIS WITH AN ILLUSTRATIVE APPLICATION TO TURKISH BANKING SECTOR PERFORMANCE
ON DIMENSION REDUCTIONS IN DATA ENVELOPMENT ANALYSIS WITH AN ILLUSTRATIVE APPLICATION TO TURKISH BANKING SECTOR PERFORMANCE

Gizay DAVER [1] , Güray KÜÇÜKKOCAOĞLU [2]


Bu çalışmada Türk Bankacılık Sektörü Performansı gelişimini ve çeşitli metodolojilerin kullanımını test ettik. Bu amaçla 2002.12 ile 2017.06 arasında çeşitli veri zarflama analizi (DEA) performans ölçüm sistematiği kullandık. Önerilen DEA modelleri, boyut azaltma tekniklerini içermektedir. Birincisi, PCA olarak kısaltılmış olan temel bileşen analizi ve ikincisi ise korelasyon bazlı DEA model kurulmasıdır. Zaman içerisinde performans değişimini inceledik ve Türk Bankacılık Sektöründeki bankaların, artan performanslarını sürdürmek için adımlar atmaları gerektiğini tespit ettik. 2001 krizinden sonra uygulanan politikalar, 2008 kriz döneminde Türk bankacılık sektöründe olumlu etkiler yaratmış, ancak kazanımlar sürdürülebilmelidir. Dört girdi ve dört çıktı faktörü kullanan ana modelimizin, araştırılan boyut azaltma tekniği yaklaşımları ile benzer sonuçlar verdiğini de bulduk.

In this study we tested the Turkish Banking Sector Performance development and the usage of various methodologies. For this purpose we used several data envelopment analysis(DEA) performance measurement systematics from 2002.12 to 2017.06. Proposed DEA models include dimension reduction techniques. The first one is principal component analysis which is abbreviated as PCA and the second one is correlation based DEA model construction. We investigated performance change over time and found that banks in Turkish Banking Sector should take steps now for maintaining their improved performances. Policies implemented after the 2001 crisis had positive effects during the 2008 crisis period in the Turkish banking sector, but gains should be sustained. We also found that our main model which uses four input and four output factors yields similar results with the investigated dimension reduction technique approaches.
