The research aims to highlight the importance of market structure and behavior on Islamic banking performance by using the Structure Conduct Performance (SCP) analysis to approximate the growth of Islamic banking performance in the short and long term using error correction model. The data used in this study is time series obtained from the financial statement of each Islamic bank, Fi-nancial Service Authority and Bank of Indonesia on Islamic banking statistics monthly reported from April, 2015 to October, 2018. Population of this study covers all Islamic commercial banks in Indonesia. The purposive sampling method is used to select samples based on criteria to get samples that are feasible to be analyzed. Error correction model is applied to characterize the joint dynamic of variables in both in the long and short term relationships. The Johansen co-integration results indicate a stable long term relation between market structure and Islamic banking performance. Results show that Market structure variable outside market share of financing in the long term had a significant effect on the Islamic banking performance, but in the short term market structure, the variable had no significant effect on the Islamic banking performance in Indonesia.
