Türk Bankacılık Sektöründe Piyasa Yoğunlaşması: 2001 Krizi Öncesi ve Sonrasının Karşılaştırılması

Piyasa yoğunlaşma endeksleri çeşitli sektörlerde rekabet düzeylerini ve piyasaya giriş-çıkış serbestilerini ölçmek için kullanılmaktadır. Bu çalışmada da 2001 krizi öncesi ve sonrası için Türk Bankacılık Sektörüne ait veriler kullanılarak yoğunlaşma düzeyi hesaplanan endeksler yardımıyla ortaya konulması amaçlanmıştır. Sektörde kriz öncesi - kriz sonrası yoğunlaşma oranlarından aktif, mevduat, kar, kredi, özkaynak büyüklükleri için anlamlı farklılık bulunmuş, 2001 krizi sonrasında sektör yoğunlaşma değerlerinin bu kriterlerde yükseldiği gözlenmiştir. Şube ve personel sayısı açısından anlamlı bir farklılığa rastlanmamıştır.

Anahtar Kelimeler:

piyasa yoğunlaşması, yoğunlaşma endeksleri, Türk Bankacılık Sektörü, 2001 Krizi

Market Concentration inTurkish Banking Sector: Before and After 2001 Crisis Comparison

Concentration indices are usually used for calculating competition levels and assessing market entry-exit conditions in various industries. Likewise in this study we aim to reveal the market concentration levels in Turkish Banking Sector for post and pre 2001 crisis periods by using concentration indices. Also to be able to make pre and post crisis comparisons t-tests are conducted. It was found that there are significant differences in market concentration levels when pre and post 2001 crisis comparisons are made. Moreover as consistent with our expectations both in terms of assets, deposits, revenues, loans, equity capital, branch and employee numbers an increase in market concentration ratios for post-2001 crisis period is observed.
