Based on the literature review and the theory of comparative advantage frontier approach, based on the main food crops in Henan Province in 2000 to 2006 acreage, yield, comparative advantages of each region carried out a more detailed analysis, combined with the current situation and thus specific analysis of the production of major food crops in Henan Province are facing form, the last actual given appropriate countermeasures. First analyzed the research background, purpose and meaning. Henan is a big agricultural province, basically solved the food and clothing problems, based on the people, in order to increase farmers' income, should pay attention to optimize the structure of grain varieties, the adjustment of agricultural industrial layout. Comparative advantage is the second agricultural policy, agricultural science and technology affecting agriculture after the primary determinant structural efficiency, research comparative advantages of major food crops in Henan, which adjust crop planting structure and layout, implementation Fuyoufuqiang non-balanced development strategy, focusing on cultivate competitive advantage of producing food crops and development, and to improve the international competitiveness of Henan Agricultural and productivity levels. Second, from the scale advantages of major food crops in Henan Province, the efficiency advantages, and other aspects of the comprehensive advantages of the analysis. Henan Province, the main food crops, only wheat, corn advantages of scale, the scale advantage index were 2.40 and 1.10, while other food crops such as rice, millet, soybeans, potatoes, etc. do not have the size advantage, especially rice, which scale advantage index of 0.20, far from scale advantages. Henan Province, the main food crops have a high index of efficiency advantages, including wheat, millet, potato efficiency has obvious advantages, its efficiency advantage index 1.16,1.00 and 1.20, respectively, while rice, corn, soybeans have weak efficiency advantages, and its efficiency advantage index were 0.98,0.91,0.96. Henan Province, the main food crops, only wheat combined strengths index reached 1.67, has obvious advantages, followed by corn, comprehensive advantages index was 0.99, while the other major food crops such as rice, millet, soybeans, potatoes, etc. do not have the comprehensive advantages Index . Finally, the restructuring of major food crops in Henan Province were analyzed. To expand the production of crops; stabilization and adjustment balance of crop production; reduce, eliminate weaknesses crop production. Under natural conditions and its comparative advantages to develop wheat, corn and other major food crops production. The province to establish a high-quality wheat, high quality corn-based industrial layout, and strive to improve wheat, maize production levels in order to improve its regional production capacity. Appropriately reduced rice, millet and other most do not have a comparative advantage in the production of food crops. Accelerate the development of farming and industrial restructuring plan, and actively adapt to the needs of consumers, efforts to improve the competitiveness of agricultural products.
