This study assesses the differences between Islamic and conventional bank’s productivity. Earlier studies on bank productivity focused on conventional banks, but few have been done on Islamic banks. Therefore, the present study attempts to close the gap in the literature by investigating the productivity of Islamic and conventional banks in the context of the Middle East, Southeast Asia and South Asia regions. The sample is comprised of 385 banks (66 Islamic banks and 319 conventional banks) from 18 countries with data observations from 2008 to 2017. Panel data techniques with DEA-based MPI will be employed to investigate the impact of selected important factor and bank productivity as indicated by total factor productivity changes (TFPCH). Based on the results, Islamic banks are more productive than conventional banks and the results from t test are further confirmed by the results from nonparametric tests. These results are attributed to the progress in EFFCH. However, the mean difference between Islamic and conventional banks TFPCH is not statistically significant in all regions. The main benefit is that this work will hopefully provide additional insight and complement the existing studies on bank productivity of Islamic and conventional banks that are important to the banks, regulations, investors and researchers.

这项研究评估了伊斯兰银行与传统银行生产力之间的差异。较早的关于银行生产率的研究都集中在传统银行上，但对伊斯兰银行的研究却很少。因此，本研究试图通过调查中东，东南亚和南亚地区背景下的伊斯兰银行和传统银行的生产率来缩小文献中的差距。该样本由来自18个国家的385家银行（66家伊斯兰银行和319家传统银行）组成，对2008年至2017年的数据进行了观察。将采用基于DEA的MPI的面板数据技术来调查选定的重要因素和银行生产率的影响。由全要素生产率变化（TFPCH）表示。根据结果​​，伊斯兰银行比传统银行生产力更高，而非参数测试的结果进一步证实了t检验。这些结果归因于EFFCH的进展。但是，伊斯兰银行和传统银行TFPCH之间的平均差异并不是在所有地区都具有统计学意义。主要的好处是，这项工作将有望提供更多的见解，并补充对伊斯兰银行和传统银行的银行生产力的现有研究，这些研究对银行，法规，投资者和研究人员至关重要。
