本文提出了一种参数前沿方法，从生产效率的角度来估计整个经济的能源效率表现。利用Shephard能量距离函数定义能源效率指数，并采用随机前沿分析技术对能源效率指数进行估计。介绍了一个案例研究，使用所提出的方法来衡量经合组织抽样国家的整体经济能源效率绩效。结果表明，与非参数前沿方法相比，参数前沿方法在能效绩效测量中具有更高的鉴别力。
This paper proposes a parametric frontier approach to estimating economy-wide energy efficiency performance from a production efficiency point of view. It uses the Shephard energy distance function to define an energy efficiency index and adopts the stochastic frontier analysis technique to estimate the index. A case study of measuring the economy-wide energy efficiency performance of a sample of OECD countries using the proposed approach is presented. It is found that the proposed parametric frontier approach has higher discriminating power in energy efficiency performance measurement compared to its nonparametric frontier counterparts.
