柯布—道格拉斯生产函数的改进与应用

The Improvement and Application of Cobb-Douglas Production Function

基于带有技术进步系数的柯布—道格拉斯生产函数对物流系统的数学模型进行改进以及实例验证,得到了当生产技术随时间变动时,能够反映技术进步对物流系统产出影响的函数模型。然后运用多元线性回归的方法对模型的参数进行检验,同时也对模型本身的显著性进行回归拟合,效果均为显著。

Improving and verifying the logistics system model based on the improved C-D production function with the coefficient of technological progress,in this paper we obtain a more advantageous model which can obviously illustrate the contribution of the technological progress on the production as it changes over time.Then the parameter estimations are cunducted and model significance regressions are proceeded,which have all proved greatly significant.
