The primary results reveal a substantial positive relationship between the regional tax ratio and economic growth, with a coefficient of 71.22%(p \u003C 0.01) . This finding suggests that increasing the regional tax ratio can effectively promote economic growth when optimally managed. However, the study also uncovers a non-linear relationship where the squared regional tax ratio has a negative impact on economic growth, with a coefficient of-2067.14%(p \u003C 0.01) beyond a certain threshold. This indicates that while moderate increases in the tax ratio can be beneficial, exceeding the optimal regional tax ratio may suppress investment and economic activity. Additionally, the research shows that the ratio of regional revenue from non-tax sources and the ratio of central government transfer revenues negatively affect economic growth, with coefficients of –39.63%(p \u003C 0.01) and –11.65%(p \u003C 0.01), respectively. Conversely, the ratio of other regional revenues demonstrates a significant positive impact on growth, with a coefficient of 9.20%(p \u003C 0.01). The study identifies an optimal regional tax ratio (RTMG) of 1.72%, compared to an average tax ratio of 1.20% during the study period, highlighting the potential for increasing the tax ratio to approach or reach RTMG to maximize economic growth. Based on these findings, it is recommended that regional governments pursue sustainable management of the regional tax ratio, diversify revenue sources, optimize the allocation of central government transfer funds, and invest in infrastructure and human capital. Routine evaluation of fiscal policies is also advised to adjust tax strategies in response to evolving economic conditions, aiming to achieve long-term sustainable economic development.  \nKEYWORDS  \nregional tax ratio, economic growth, fiscal policy, panel data, Fixed Effects Model JEL H71, H77, O18, R58  \nУДК 336.22  \nАнализ оптимального налогового соотношенияи эффективности региональных налоговых доходов:  \nисследование провинций Индонезии  \nЙосиномита Йосиномита􀀍, Эфияльди, Аю Фераника, Мардиана Р,Ирфан Хассанди, Мира Густиана Пангесту, Йоси Фахдилла  \nУниверситет Динамика Банса, г.
