Measurement of Dynamic Efficiency: A Directional Distance Function Parametric Approach
提出一种参数化方法估计动态效率，基于方向性距离函数及其对偶关系，测算荷兰奶牛场的技术与配置效率，发现长期成本可节省约12%。
This research proposes a parametric estimation of the structural dynamic efficiency measures proposed in 2009 by Silva and Oude Lansink. Overall, technical and allocative efficiency measurements are derived based on a directional distance function and the duality between this function and the optimal value function. The applicability of the parametric proposal is illustrated by assessing dynamic efficiency ratings for a sample of Dutch dairy farms observed from 1995 to 2005. Dynamic efficiency ratings indicate the possibility to achieve long‐run cost savings on the order of 12% that are mainly to be accomplished through a reduction in input use.
