Taiwan's guaranteed rice purchase system, in place since 1974, has been crucial for stabilizing farmers' income but has led to overproduction and increased government financial burden. The government has been promoting rice conversion to other grains to ease overdependence on imported goods and balance supply and demand. However, challenges persist, such as the impact of the system on market prices and the need for comprehensive policy reviews that consider all cereals and the balance between industrial structure and resource allocation. The article underscores the complexity of agricultural policies, requiring involvement from various departments and stakeholders. It also discusses the potential of referencing international experiences and the importance of continuous policy adjustments and dialogue with key stakeholders for a sustainable and balanced agricultural policy in Taiwan.
