In 2016，the grain supply was a little bit more than the demand，mainly because of the large stock and high yields. Affected by the planting structure adjustment and natural disasters，the grain yield slightly went down，while the production of soybean，beans，and potatoes went up. Because of the reasons，such as the demand caused by the structure adjustment and the difference in the domestic and international markets，the import of rice，wheat and soybean continuously increased，while corn and its substitutes declined sharply. Affected by the relationship of supply and demand and the adjustment in the corn storage policy，the producer price of rice，wheat and corn declined，of which the corn price fell the most. Comprehensively considering the international market and domestic policy adjustment，we have the follow expectations for the next year. The yields of rice and corn would decline，while the yields of wheat，soybean，beans，and potatoes would increase. The rice price would fall. The wheat price would remain stable. The price of corn and soybean would fluctuate. The pressure on the import of rice，wheat，corn，and soybean would decline.
