Empirical analysis shows that the minimum purchase price published annually by the government has significant positive impact on farmers' grain supply in the major grain producing areas. In recent years,China steadily raises the level of minimum grain purchase price,which has played an important role in effectively protecting grain farmers' interests,mobilizing the enthusiasm of farmers' grain production,and ensuring the market supply of key grain varieties.展开更多
