摘要
针对"三农"中粮食生产成本快速攀升问题,收集三种粮食生产成本明细数据,通过多元回归分析法,构建三种粮食生产成本模型,F检验表明回归方程总体显著,t检验显示生产总成本与生产子成本之间存在显著的线性关系。研究结果表明,人工费用上升和直接费用不断提高是导致粮食生产成本上升的主因,因此降低三种粮食生产成本需要物化劳动替代活劳动,改变农业补贴方式,提升粮食价格的建议。
In view of the quickly increasing agricultural production costs, we have collected three grain's production cost detailed data over years. The cost models of three grain production have been built by means of the multiple regression method. F test indicates that the whole regression equation was obvious and there was an obvious linear relationship between the total production cost and the sub- production cost. The results showed that the increase of labor cost and direct material cost was the main cause for the increase of the grain production cost. Therefore, this paper suggested that mechanical input should take place of the human input and the mode of agricultural subsidies should be changed reasonably. Moreover, the price of grain should be increased to reduce the cost of three kinds of grain production.
