These problems will lead to a growing gap in grain supply and demand year by year, which to some extent restricts the sustainability of grain supply. At the same time, these problems have "crowding out effect" on grain scale production. Therefore, this paper analyzes the foothold, point of view, focus point and equilibrium point of Chinese food security strategy and grasp Chinese food security strategy from a macro perspective.
