Abstract: The Human Development Index (HDI) serves as a critical barometer of local government performance, yet high aggregate scores often conceal stark regional disparities. This study investigates the impact of education and health expenditure on the HDI across 154 regencies and municipalities in Sumatra, Indonesia, during the 2020–2024 period. Employing a quantitative approach with panel data and multiple linear regression analysis using SPSS, the study tests the partial and simultaneous effects of per capita education and health spending on HDI. The results reveal that both education expenditure (β = 0.314; p < 0.05) and health expenditure (β = 0.228; p < 0.05) have a positive and significant effect on HDI, with the model explaining 42.1 percent of HDI variation (Adjusted R² = 0.421). Education spending exerts a relatively stronger influence than health spending. These findings confirm that public social sector investment is vital for human development; however, its effectiveness varies spatially, with regencies in remote and archipelagic areas experiencing diminishing returns. The study contributes to the literature by highlighting that closing development gaps requires not merely increasing budgets, but formulating spatially adaptive fiscal policies tailored to the unique geographical challenges of each region.
