本文研究了1996-2002年期间，在10个国家经营伊斯兰银行业务的伊斯兰和传统银行的样本的效率，使用输出距离函数法。我们获得的效率措施后，考虑到环境的影响，如国家宏观经济条件，银行服务的可及性和银行类型。虽然这些因素被认为是直接影响技术的形状，我们假设，国家假人和银行规模直接影响技术效率。参数估计值突出表明，在样本期间，伊斯兰银行业似乎与较高的投入使用有关。此外，通过考虑银行规模和国际差异的基本无效率分布，我们也能够证明统计上显着的差异，即使在控制特定的环境特征和伊斯兰银行的低效率相关的这些因素。因此，例如，我们的研究结果表明，苏丹和也门有相对较高的无效率，而巴林和孟加拉国有较低的估计无效率。除了苏丹的银行表现出相对较强的规模收益外，大多数样本银行的规模收益都很小，尽管伊斯兰银行的规模收益略高于传统银行。虽然这表明伊斯兰银行可能从规模扩大中受益，但我们要强调的是，我们的研究结果表明，确定和克服导致伊斯兰银行在给定投入使用水平下潜在产出相对较低的因素，将是伊斯兰银行业在未来几十年面临的主要挑战。
The paper investigates the efficiency of a sample of Islamic and conventional banks in 10 countries that operate Islamic banking for the period 1996-2002, using an output distance function approach. We obtain measures of efficiency after allowing for environmental influences such as country macroeconomic conditions, accessibility of banking services and bank type. While these factors are assumed to directly influence the shape of the technology, we assume that country dummies and bank size directly influence technical inefficiency. The parameter estimates highlight that during the sample period, Islamic banking appears to be associated with higher input usage. Furthermore, by allowing for bank size and international differences in the underlying inefficiency distributions, we are also able to demonstrate statistically significant differences in inefficiency related to these factors even after controlling for specific environmental characteristics and Islamic banking. Thus, for example, our results suggest that Sudan and Yemen have relatively higher inefficiency while Bahrain and Bangladesh have lower estimated inefficiency. Except for Sudan, where banks exhibits relatively strong returns to scale, most sample banks exhibit very slight returns to scale, although Islamic banks are found to have moderately higher returns to scale than conventional banks. While this suggests that Islamic banks may benefit from increased scale, we would emphasize that our results suggest that identifying and overcoming the factors that cause Islamic banks to have relatively low potential outputs for given input usage levels will be the key challenge for Islamic banking in the coming decades.
