PSP

When analyzing the impact of the Price Support Policy (PSP), data on grain prices, import and export volumes, and production levels were used. The price data included domestic purchase prices and international market prices for major grains such as rice and wheat. Import and export statistics were sourced from customs databases, covering annual trade flows over the study period. Production data encompassed total output, yield per unit area, and sown area, derived from national agricultural statistical yearbooks. All data were cross-verified for consistency and reliability before being incorporated into the analysis.
