利用具有不同规模收益的不良产出导向数据包络分析模型，研究了中国所在的30个行政区交通运输业的二氧化碳排放状况。实证结果表明，有效区域数量自2004年以来有所减少，在2006年达到历史最低水平，之后略有改善。总体平均绩效评级在2004年达到顶峰，并持续下降，直到2006年达到最低纪录。尽管2007年略有上升，但自2008年以来，绩效评级一直在下降。这一格局与十一五(2006-2010年)交通运输部门的政策导向是一致的。总体而言，通过调整不良产量(二氧化碳)，东部中国的表现好于中部和西部。然而，通过调整二氧化碳排放量和理想产出，中部地区的表现好于东部和西部地区。这可能是因为交通基础设施高度集中在东部和空间集群。集群就像阶梯一样，从较高的东部到中部，再到较低的西部。这表明，交通基础设施的发展在中国是齐头并进的。因此，东方可能不会有太大的改善空间，通过调整理想的产出。
Undesirable output-oriented Data Envelopment Analysis (DEA) models with different return of scales are used to study the CO2(Carbon dioxide) emissions performance of the transport sector throughout China's 30 administrative regions. Empirical results show that the number of efficient regions has decreased since 2004, hitting the lowest record in 2006, and improving slightly afterwards. The overall average performance rating reached its peak in 2004 and continuously decreased until it hit its lowest record in 2006. Although it slightly increased in 2007, performance rating has decreased since 2008. This pattern is consistent with the policy guidance of the transport sector in the 11th Five-Year Plan (2006–2010). In general, Eastern China performed better than Central and Western by adjusting undesirable output (CO2). However, Central performed better than Eastern and Western by adjusting both CO2emissions and desirable outputs. It may be because that transport infrastructure facilities are heavily concentrated in Eastern and spatial clusters. The clusters are like stair steps decreasing from the higher Eastern to Central then to the lower Western. This indicates that the development of transport infrastructure go hand in hand in China. Hence, Eastern may not have too much improvement room by adjusting desirable outputs.
