【摘要】 以河南省农业水资源生产为考察对象,研究了2005至2011年河南省粮食生产投入产出效率,运用投入导向的DEA方法得到计算期间农业用水等投入指标的技术效率,规模效率,结果表明农业用水和其它投入性指标具有一定的要素替代性,在粮食生产技术和规模有效的条件下,通过提高劳动力、农机动力、农药化肥等生产投入性指标的效率,稳定或减少农业用水数量,可以保障粮食生产稳产增产。更多还原

【Abstract】 Study on the production of agricultural water resources and input-output efficiency of grain production from 2005 to 2011 of Henan Province. Use the investment orientation of DEA method to calculate technical efficiency and scale efficiency of input indicators. The results show that agricultural water and other indicators have factor substitution. If the grain production is technical efficiency and scale efficiency, improve the efficiency of the labor force, the power of agriculture machinery, pesticide and fertilizer, stabilize or reduce the amount of agricultural water, can guarantee the grain production yield.更多还原
