The purpose of this study is to examine the effect of the minimum wage of regencies/cities (UMK), investment, labor force participation rate (TPAK), and average length of schooling (RLS) on income inequality in 14 regencies/cities in West Kalimantan Province during the period 2014–2023. The methodological approach used is panel data regression with the Random Effect Model (REM). The findings show that the UMK and investment variables have a negative and significant impact on income inequality, indicating that increases in both aspects can contribute to reducing inequality. On the other hand, the TPAK variable shows a positive but insignificant effect, while the ALE has a positive and significant effect, indicating that increases in average years of schooling have not been evenly distributed and may even widen income gaps. Simultaneously, all four variables were found to have a positive and significant effect on income inequality.
