Regional disparity analysis of Chinese freight transport CO2 emissions from 1990 to 2007: Driving forces and policy challenges

Freight transportation and logistics act as the artery of the national economy. With a booming economy, China's freight transport sector has experienced dramatic growth in recent decades and has become a key driving force of China's CO2 emissions. Therefore, effective and efficient mitigation policies in the freight transport sector are critical for China to promote CO2 emission mitigation strategies. In contrast to other countries, China's challenge stems not only from technical issues but also from regional socioeconomic disparities, which in turn require the implementation of locally oriented policies. For this reason, an analysis based on regional disparity is of vital importance for future policy making. However, to date, there have been few pertinent studies on the freight transportation sector. To fill this gap, this paper aims to conduct an in-depth comparative study of CO2 emission characteristics and the driving forces in the freight transport sector in China's three regions (covering 31 provinces) from 1990 to 2007. The log mean Divisia index method (LMDI) is employed to analyse the driving forces, and the Gini coefficient is used to investigate regional inequity. Additionally, regional disparity is explored in-depth based on the analytical results and practical concerns. The results highlight that economic structure is a key driving force for emissions change and reveal significant regional disparity and inequity in freight transport emissions. The results are critical for future policy-making to address regional concerns. (C) 2016 Elsevier Ltd. All rights reserved.
