Regional disparities and influencing factors for carbon productivity change in China’s transportation industry

The transportation industry is the important component of the national economy as well as emissions reductions, however, few previous studies have investigated the carbon productivity (CP) of the transportation industry in China. This study attempts to fill this gap by researching the regional disparity and influencing factors of CP of China’s transportation industry over the 10th, 11th, and 12th Five-Year plan periods. Specifically, the authors developed an integrated CP decomposition approach by combining the Log Mean Decomposition Index approach and production-theoretical decomposition approach. As such, CP was first decomposed into technological innovation effect, regional adjustment effect, CO₂ emission efficiency effect, and technical change of CO₂ emissions effect. The results revealed the following: (1) during the study period, China’s transportation CP showed a general downward trend; (2) regional disparity in CP narrowed primarily because of intragroup inequity; (3) technological innovation effect and total-factor regional adjustment effect on CP change did not play a significant role in prompting CP. Based on the empirical results, the authors provide some policy proposals.
