The transportation sector is one of the important energy consumption and carbon emission sources. This paper extends the multi-directional efficiency analysis (MEA) to zero-sum game MEA (ZSG-MEA) with considering the CO emission as a fixed-sum undesirable output to measure the energy and environmental performance (EEP) of the transportation sector. The ZSG-MEA window analysis is applied to dynamically evaluate the EEP of China's transportation sector in 30 provincial-level regions during 2008-2017. Some interesting findings are obtained: (i) the EEP of the transportation sector in most regions has not been performed well but the average EEP of the transportation sector in most regions has been gradually improved since 2011. A general trend is that the transportation sector in the east area wins the best average EEP, and the average EEP of the central area is better than that of the west area, but their gap is narrowing from 2012. (ii) The EEP fluctuation verifies the greatest imbalance of EEP among the east area's regions. Both the east area and the central area are narrowing the imbalance in recent years, but the west area has an inverse trend. (iii) The performance of CO emissions is better than that of energy consumption in all three areas, which implies that China's transportation sector seems to have paid more attention on emission reduction than energy conservation. Besides, the east area has the best performance of energy consumption and CO emissions from an overall perspective. And the energy consumption and CO emissions in the central area perform better than the west area before 2013, but then shows an entangled state from 2013. (iv) From the average variable specific ZSG-MEA efficiency, the industrial added value of transportation sector performs better than other variables in the east area and central area, but the situation in the west area is inverse. Some useful insights are provided according to these findings.
交通运输部门是能源消耗和碳排放的重要来源之一。本文将多向效率分析（MEA）扩展到考虑 CO 排放为固定和不良输出的零和博弈 MEA（ZSG-MEA），以衡量交通运输部门的能源和环境绩效（EEP）。应用 ZSG-MEA 窗口分析方法，动态评估了 2008-2017 年中国 30 个省级行政区交通运输部门的 EEP。得到了一些有趣的发现：（i）大多数地区的交通运输部门 EEP 表现不佳，但自 2011 年以来，大多数地区的交通运输部门平均 EEP 逐渐提高。总体趋势是，东部地区的交通运输部门获得了最佳的平均 EEP，中部地区的平均 EEP 好于西部地区，但从 2012 年开始差距逐渐缩小。（ii）EEP 波动验证了东部地区各地区之间 EEP 最大的不平衡。近年来，东部地区和中部地区都在缩小不平衡，但西部地区呈相反趋势。（iii）所有三个地区的 CO 排放绩效均优于能源消耗绩效，这意味着中国交通运输部门似乎在减排方面比节能方面投入更多。此外，从整体上看，东部地区的能源消耗和 CO 排放绩效最佳。在 2013 年之前，中部地区的能源消耗和 CO 排放绩效优于西部地区，但从 2013 年开始呈现纠缠状态。（iv）从平均变量特定的 ZSG-MEA 效率来看，交通运输部门的工业增加值在东部地区和中部地区的表现优于其他变量，但西部地区的情况相反。根据这些发现，提供了一些有用的见解。
