Abstract
This study aims to determine the primary, secondary and tertiary sectors' economic structure that affects income inequality in Sulawesi. The data used in this study is secondary data in the form of 6 provinces on the island of Sulawesi with a period of 2011-2020 sourced from journals, articles, and government institutions such as BPS. The analysis technique used is panel data regression. The results of this study indicate that the effect of the primary economic structure on income inequality is positive and significant. Regional income inequality will increase in Sulawesi between 2011 and 2020 as the primary economic structure develops. The impact of the secondary sector's economic structure on income inequality is negative and significant. This means that income inequality between Sulawesi regions will decrease from 2011-to 2020, along with the increase in the secondary economic structure. The effect of the tertiary sector economic structure on income inequality is positive and significant. With the increase in the tertiary economic structure, income inequality between regions will increase during the 2011-2020 period.
