Abstract:

The situations of new Chinese maize production and consumption were reviewded in the paper.Though Chinese maize industy has developed rapidly and made great achievements, it will be more difficult to continue improving its production capacity.The maize consumption growth is in a rigid trend,and the maize oversupply will be gradually transformed into balance,even into relatively tight supply.The pressure on effective self-sufficiency is mounting,the industry uncertainties are increasing,and the danger is expanding.The constraint factors including the shortage of agricultural resources,the structural contradiction of varieties,the low level of mechanization,etc. were analyzed,and some appropriate countermeasures such as scientific utilization of agricultural resources,optimization of varieties and regional distribution ,promotion of mechanization and so on were put forward to guide people to recognize Chinese maize indutry and take effective measures to promote more healthy and orderly maize industry development.
