      abstract = {This paper uses the location quotient index and relative  growth rate to measure the comparative advantage in the  production of rice, wheat, corn and soybeans in different  provinces of China. The result shows that there exists  great difference in the production of major grain varieties  in different areas of China and that the northern areas are  accumulating their competence. Because great changes have  taken place in the space structure of the production of  major grain varieties and water resources will constitute a  rigid restraint in the production of grain, it will become  the priorities in guaranteeing the Chinese future food  safety to promote the nurturing of areas with advantage in  the production of corn and soybeans, and it will become the  key for guaranteeing the balance between the demand and  supply of grain to enhance the development of grain  circulation system.},
