This research characterizes economic growth through the Gross Regional Domestic Product (GRDP) for each province in Indonesia. This study utilizes secondary data from 2011 to 2022 sourced from BPS, OJK, and Bank Indonesia, analyzed using the Path Application. This report assesses the direct and indirect funding of Islamic banks and their involvement in economic growth via Micro, Small, and Medium Enterprises (MSME) credit. The research findings indicate that the Islamic bank funding variable does not significantly influence the MSME credit variable; nevertheless, the investment variable does have a substantial impact on the Micro, Small, and Medium Enterprises (MSME) credit variable.
