阶段C—D前沿生产函数的DEA估计

Stages "C - D" Frontier Production Function Estimated by Data Envelopment Analysis

由于采用一般参数估计方法,估计出的C—D生产函数与生产函数的定义不符,因此本文提出了一种更符合生产函数定义的C—D生产函数的DEA估计方法,利用这种方法估计出的生产函数是由各决策周期内不同投入组合所带来的最大产出点构成的.由于它处于生产最前沿,并且呈动态阶段性,因此称它为阶段C—D前沿生产函数.同时,本文给出实际生产过程向前沿生产过程转化的方向和程度.

Stages 'C -D'Tront production function estimated by Data Envelopment Analysis (DEA) does not tally with the defination of production function. So, in this paper a more suitable method is proposed which is estimated by DEA. The estimated production function, derived by above method, is composed of some maximun production points which results from different combination of factors of production in correspondent decision period. It's on the frontier of production and is dynamicinstage. Therefore, we consider it as stages 'C -D'frontier production function .and also point out the direction and extent of transformation of real production process to frontal production process.
