Abstract
Concentration, competition and efficiency are three elements that are often
associated with the banking industry. Banking industry in most of the countries in
the world had undergone tremendous changes due to several structural changes
occurred in the industry. Malaysia has also not left behind in facing this wave of
change. There are four main sources that contribute to the structural changes in the
Malaysian banking industry namely, bank mergers, implementation and
restructuring of Islamic banking industry, liberalization and advancement in
information and communication technology (ICT). Besides, the 1997 East Asian
Financial Crisis and restructuring of banking industry under the Financial Sector
Master Plan also have contribute to the aggressive structural changes in the
Malaysian banking industry. Thus, the main purpose of this study is to investigate
the impact of structural changes on the degree of concentration, competition and
performance of the Islamic banking system compared to conventional banking
system in Malaysia.
This study used the data of both domestic and foreign banks which operated in dual
banking industry in Malaysia, covered the period 1997-2016. The research method
in this study has been developed properly to achieve the objectives of the study.
First, this study utilizes structural approach to measure various types of market
concentration indices, calculated on year-to-year basis in order to investigate the
link between concentration and competition. All measures of concentration have
been calculated using the formulas proposed in the industrial organizational theory.
Second, this study developed the Panzar-Rosse (PR) model to calculate the Hstatistics
to determine the degree of competition in Islamic and conventional
banking markets. Third, the data envelopment analysis (DEA) method is used to
measure income and cost efficiency scores. Finally, the calculated measures of concentration, competition and efficiency are included in a model in order to
estimate the relationship between those variables. All the econometric models in
this study are estimated using pooled cross-section (OLS) and panel estimation
approach (fixed and random effects).
Findings of this study are as follows. First, analysis on market concentration
provides evidence on the decreasing trend in the level of concentration of Islamic
banking market. In contrast, level of concentration is increasing in the conventional
banking market. Second, the H-statistics computed using the PR model shows both
banking markets operated under the monopolistic competition structure. However,
level of competition is more intensifying in the Islamic compared to conventional
banking market. Third, results on efficiency scores show that Islamic banks are
more cost efficient, but conventional banks are more efficient in generating
income. Fourth, the results on the nexus between competition, concentration and
efficiency show the existence of negative relationship between competition and
concentration; and a positive relationship between efficiency and competition.
Based on these findings, this study concludes that the existence of an ideal level of
concentration and competition is important for banks to adjust their behaviour to
suit market conditions and to operate efficiently. Besides, policy makers and
regulators may use the knowledge on market structure and performance in this
study to formulate policies and strategies that will optimize the number of banks
that operated in the industry.
