摘要
测算出农业机械化对农业生产的贡献份额,对农业机械化事业的决策具有重要的参考价值.本文运用生产函数法定量计算农业机械化投入对农业产出的贡献率,采用Visual Basic(VB)编程对统计数据进行有效处理,再进行回归分析;以湖南省为实例,计算得到农业机械化贡献率的数学模型,并结合模型分析了各生产要素对农业产出的影响程度.
Profit Portion estimation for the mechanization in agricultural industry is useful to understand the development level, potential, trend of agricultural mechanization for government strategic decision-making. Based on the method of Cobb-Douglas production functions, the mechanization profit portion in agricultural industry in Hunan Province was estimated quantitatively. During the estimation, the thesis got the regression model by using Visual Basic 6.0 version because it is difficult to get the coefficient of every factor＇s output elasticity.
