摘　　要：分析小麦生产中不同生产要素投入对产量的影响,有利于优化生产投资结构、减少生产投资成本、确保小麦产量提高。鉴此,以河南省安阳县、沈丘县、新蔡县农户投入数据为基础,采用扩展的生产函数模型进行分析。结果表明,各地区影响小麦单产的主要投入因素基本相同,主要有单位面积化肥投入、种子投入、农业机械投入、农药投入等,这些因素在不同地区相对影响程度又有所差别。单位面积劳动投入量不再是影响小麦单产的主要因素。Study on the effect of different production investment on wheat yield was helpful to optimize production investment structure,to reduce production cost and to ensure improving wheat yield.Based on the farmers＇data of Anyang county,Shenqiu county and Xincai county in Henan province,the extended C-D production function model was used for analysis.The result showed that the main input factors affecting yield per unit area were similar in different areas,and the factors were fertilizer input,seed input,agricultural machinery input,pesticides input per unit area.The relative importance of these factors was a little different in different areas,and labor input was not a main factor any more.
