Analysis of the Low-Carbon Efficiency of Chinese Transport Sectors from 2007 to 2015
To evaluate the carbon emission efficiency of transport sectors in China, the concept of low-carbon transport efficiency (LCTE) is proposed. On this basis, the LCTE in China’s provinces and autonomous regions is calculated using the evaluation method of cross-data envelopment analysis (DEA) with the data during the period of 2007–2015. The result shows that the overall level of China’s LCTE is mostly in the middle and lower level, meanwhile the difference of provincial and autonomous regions is great. This means there is a lot of room for China’s low-carbon transport efficiency to improve. The average value of LCTE is 0.54, which shows a steady trend of development from 2007 to 2013. While there are large fluctuations from 2013 to 2015 in many provinces and autonomous regions, of which Ningxia and Liaoning are the largest, whose change are the decrease of 40.7% and the increase of 79.1%, respectively. This indicates that current situation of transport carbon emission in China is not optimistic, and the main reason is that the western region is relatively backward.
