In 2017，although the planted area of grains reduced under the central government’s guidance，the grain production still increased slightly，mainly because of the suitable weather，effective disaster reduction technical improvement. The role of market had a further important role in the formation of grain prices，with the improvement in the formation mechanism of grain prices and the advancement in the reform of the storage system. The import of rice，wheat，and soybeans increased largely，but corn import decreased，due to the structural shortage and the big difference in the prices between the domestic and international markets. In 2018，the grain production and market will change，under the influence of relevant policies. Firstly，the rice price would probably go down；the wheat price will be relatively stable；and the price of corn and soybeans would probably fluctuate within a certain range. Secondly，the yield of rice might decline；the wheat yield might remain relatively stable，and yield of corn and soybean might rise. Lastly，pressure on the import of rice and corn might be low，but still high on the import of wheat and soybeans.
