The results shows that, whether in a system of linear or nonlinear range, corn prices have a more important influence on wheat prices; it finds that the relationship between corn and wheat prices will affect the market supply and demand change, mainly for the replacement on demand of forage consumption and import supply; after implementing the corn market pricing and subsidy policy, the price of wheat formation mechanism also needs to improve in time-.
