Abstract
Abstrak
Artikel ini mempunyai tujuan untuk mengetahui keseimbangan pendapatan nasioanal dalam tiga sektor dan empat sektor. Penelitian ini menerapkan evaluasi mendalam melalui metode pengumpulan data sekunder, termasuk penelitian pustaka dan pencarian internet. Data diperoleh dari jurnal dan artikel yang berfokus pada tiga sektor dan empat sektor. Hasil menunjukkan bahwa dalam perekonomian tiga sektor, pemerintah memiliki peran signifikan dalam mengatur kebijakan pajak dan pengeluaran, sementara dalam perekonomian empat sektor yang lebih realistis, impor dan ekspor juga memainkan peran penting dalam mencapai keseimbangan ekonomi. Kurva fungsi ekspor bersifat horizontal karena ekspor bersifat otonom, sementara kurva impor cenderung naik karena impor meningkat seiring dengan pendapatan nasional. Dalam keseimbangan ekonomi empat sektor, pendapatan nasional sama dengan pengeluaran agregat, yang meliputi konsumsi, investasi, pengeluaran pemerintah, serta selisih ekspor dan impor.

Abstract
This article aims to determine the balance of national income in three sectors and four sectors. This research applies in-depth evaluation through secondary data collection methods, including desk research and internet searches. Data were obtained from journals and articles focusing on three sectors and four sectors. The results show that in a three-sector economy, the government has a significant role in regulating tax and spending policies, while in a more realistic four-sector economy, imports and exports also play an important role in achieving economic equilibrium. The export function curve is horizontal as exports are autonomous, while the import curve is upward sloping as imports increase along with national income. In a four-sector equilibrium economy, national income equals aggregate expenditure, which includes consumption, investment, government spending, and the difference between exports and imports.
Keywords: Economic Equilibrium, Three-Sector Economy, Four-Sector Economy
