中文摘要	基于投入产出比的视角,以柯布-道格拉斯生产函数为基础,对民乐县主要农作物的经济效益、投入成本及单方水效益进行了测算。结果表明,由于劳动力成本投入较高、作物种植机械化水平低,民乐县主要农作物经济效益相对较低;化肥、种子、水费在作物成本投入中所占比重较大;比较大麦、小麦、马铃薯(克新)、玉米和油菜5种主要农作物,油菜的单方水效益最高,最能有效利用水资源,而大麦则是最耗水作物。通过运用Stata软件,将各项成本对作物单位产值的影响程度进一步分析后表明,劳动力对大麦产值影响显著,即大麦为劳动密集型农作物;种子、化肥、机械投入对不同作物单位产值的影响程度差异性显著;水费投入对小麦、玉米和油菜的单位产值影响显著。因此,在水资源极为短缺的内陆干旱区,农户在未来种植中应参照农作物投入产出效率,从有效利用水资源,提高水效率和效益出发,选择经济效益与节水效率优化组合。
英文摘要	This paper based on the perspective of input-output ratio, taking Cobb Douglas production function as the basis, calculates the main crops’economic benefit, cost and per cubic meter water’s benefit in Minle County. The results show that the main crops’economic benefit in Minle County was relatively low due to high labor cost and low crop planting mechanization level. Fertilizer, seed and water accounted a larger proportion in crop cost investment; comparing with barley, wheat, potato (Ke Xin) and corn, per cubic meter water’s benefit of rape is the highest; barley is the first water consumption crops. By using Stata analysis software, this paper concluded that the influence degree of different cost in per unit of crops output further showed that barley was the labor intensive crops. Seed, fertilizer, machinery inputs have significant impact on the different crops unit production, water has significant impact on the unit production output of wheat, corn and rape.Therefore, in the inland arid region which is extremely short of water resources, farmers should have the reference of input and output efficiency in future crops planting, choose optimization of economic benefit and water saving efficiency from the perspective of effectively using water resources, improving water efficiency and benefit.
