本文提出了一种非径向方向距离函数方法，从生产效率的角度来模拟发电的能量和CO2排放性能。我们首先定义和构建的环境生产技术的国家和没有热电联产厂，分别。提出了非径向距离函数方法，并建立了衡量发电能量和CO2排放性能的指标体系。所建立的方向距离函数可以通过求解一系列数据拟合分析模型来计算。然后，我们使用100多个国家的数据集进行实证研究。研究发现，在发电方面，OECD国家的碳排放绩效和综合能碳绩效均优于非OECD国家，而能源绩效差异不显著。
This paper presents a non-radial directional distance function approach to modeling energy and CO2emission performance in electricity generation from the production efficiency point of view. We first define and construct the environmental production technologies for the countries with and without CHP plants, respectively. The non-radial direction distance function approach is then proposed and several indexes are developed to measure energy and CO2emission performance of electricity generation. The directional distance functions established can be computed by solving a series of data envelopment analysis models. We then conduct an empirical study using the dataset for over one hundred countries. It is found that OECD countries have better carbon emission performance and integrated energy-carbon performance than non-OECD countries in electricity generation, while the difference in energy performance is not significant.
