摘要：
This paper introduces the social development index (SDI) into the evaluation framework of comprehensive transportation green efficiency (CTGE), and uses the SBM model, Dagum Gini Coefficient and the data from 30 regions in China to estimate and explore the CTGE and its spatial characteristics. The results indicate that: the social development index can significantly improve the CTGE, but the overall level of CTGE in China was relatively low, with great regional differences and obvious spatial imbalance. The spatial disequilibrium of CTGE had obvious stage characteristics, and the regional differences gradually expanded in the initial stage of the study, but gradually shrunk in the later stage of the study. The overall CTGE in China was different among regions. Intra-regional differences was the largest in the west and the smallest in the east, and was the main source of total disparity. At last, some relevant policy suggestions are proposed based on the research conclusions. © 2022 Science Press. All rights reserved.
