要落实减缓二氧化碳的“共同但有区别的责任”原则，就需要了解不同国家的二氧化碳排放绩效和技术差距。本文采用Meta前沿和非径向方向距离函数，提出了一种替代的三阶段方法来衡量全要素CO2排放绩效和技术差距。第一阶段计算组边界的CO2排放性能。第二阶段使用这些结果来计算技术差距比率。第三阶段综合前两个阶段的数据，计算Meta边界下的CO2排放绩效。该方法比文献中的其他方法更易于应用，并有效地避免了技术差距比大于1的现象。所提出的方法还可以将CO2排放绩效损失分解为两类：管理效率低下和技术差距。为了证明这一方法，利用54个国家的数据进行了实证分析。该研究强调了三个主要发现。首先，中上收入国家的表现不如高收入国家和中低收入国家。第二，高收入国家一般享有优化的生产技术，而中低收入国家的技术水平一般最低。第三，管理效率和技术差距均对CO2排放绩效产生负面影响，但管理效率起主导作用。(C)2016爱思唯尔B.V.保留所有权利。
Implementing the "common but differentiated responsibilities" principle for CO2 mitigation requires an understanding of CO2 emission performance and technology gaps in different countries. This paper uses a meta frontier and non-radial directional distance function to propose an alternative three stage approach to measure total-factor CO2 emission performance and technology gaps. The first stage calculates the CO2 emission performance of the group frontier. The second stage uses these results to calculate the technology gap ratio. The third stage integrates data from the first two stages to calculate CO2 emission performance under the meta frontier. This approach is easier to apply than other approaches in the literature, and effectively avoids the phenomenon of the technology gap ratio being greater than unity. The proposed approach can also decompose CO2 emission performance loss into two categories: management inefficiency and technical gaps. To demonstrate the method, an empirical analysis using data for 54 countries was conducted. The study highlighted three main findings. First, upper-middle income countries did not perform as well as high income countries and lower-middle income countries. Second, high income countries generally enjoy optimized production technology, whereas the lower-middle income countries generally had the lowest technological levels. Third, both management inefficiency and technical gaps negatively impacted CO2 emission performance, but management inefficiency played a dominant role. (C) 2016 Elsevier B.V. All rights reserved.
