Abstract: This paper proposes a new index to measure the spatial carbon intensity inequality. To further explore factors causing the inequalities of carbon intensity, meta-frontier DEA-based decomposition approach is used in this study. Using this method, carbon intensity inequality of China's transport sector from 2004 to 2018 were decomposed into nine factors, including two newly proposed technological gap factors. Study shows that: (1) there are spatial inequalities in carbon intensity of China's transport sector, which peaked in 2009 and then decreased; (2) potential energy intensity, production technology gap, and production technology contributed the most to spatial inequalities of low-carbon development in Chinas transport sector, followed by pure production efficiency and energy structure. Energy-saving technology, energy technology gap, and pure energy efficiency contributed have relatively little impacts; and (3) production technology gap is the determinant factor for the transport carbon intensity inequality between eastern and western regions. The proposed approach can also be used for many other similar low-carbon development studies.
