The Contribution of Profit-sharing Characteristics to the Performance of Islamic Banks

Islamic commercial banks are highly identic with the profit sharing as a sharia banking basic operational system. The profit-sharing becomes a specific characteristic of sharia banks as well as a distinction from conventional banks. Hence, this study aims to examine if the profit-sharing characteristic contributes to the performances of Islamic commercial banks in Indonesia. This study employed time series data derived from the Financial Service Authority (OJK) using regression mixed test and auto-regressive heteroscedasticity (ARCH). The results pointed out that the profit-sharing system for the lending of Musharaka had an impact on the performance of sharia banks; while the profit-sharing for the funding of Mudaraba did not support the hypothesis with negative coefficient. The results suggest that the profit-sharing characteristic provides contribution to the performance of Islamic commercial banks through the lending of Musharaka. These results further indicate that the profit-sharing characteristic performed by Islamic commercial banks is proven to be effective in improving their performances. This study's results have an implication for Islamic commercial banks to strengthen their profit-sharing characteristics and improve the public trust toward sharia banking syste
