Study on Major Function Oriented Zoning by Agricultural and Comparison of the Agricultural Development in the Central Plains Economic Region
基于主导功能区理论，将中原经济区划分为五个农业区，比较其技术装备、投入产出效率及全要素生产率，发现各区效率与经营类型高度相关，总体生产率下降且分化明显。
According to the theory of Major Function-Oriented Zone,the Central Plains Economic Region(CPER) can be divided five agricultural areas,the agricultural development level trends to be different.The extent of technical equipment in the agricultural areas of Zhengzhou city,the mechanization and chemicalization in surrounding agricultural areas of city group of central plains,and the irrigation in the Huanghuaihai special agricultural area are in a higher level,while the agricultural inputs in conservation and protection of southwest areas are in a low level overall.The input and output efficiency of the five agricultural areas is not completely positive changes with its input intensity,but is highly correlated with its farming operation type.The production efficiency of the Huanghuaihai area and w eastern ecological conservation and protection area which make grain as the main body is at a disadvantage,while the other areas are better.In general,the total factor productivity of the five agricultural areas is on the decline,and the differentiation is obvious.The classification guidance for the districts functions,outstanding the focal points,advancing in echelon,and the coordinated development are the keys to the coordinated development of modern agriculture in CPER.
