Abstract

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.

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

Abstract

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.
