Carbon emission efficiency evaluation of Beijing-Tianjin-Hebei logistics industry based on SBM model

The establishment of a sound low-carbon logistics system is the basic solution to China?s resource, environmental and ecological problems. From the perspective of resources, environment and ecology, building a low-carbon logistics system is the basic solution to the problems of resources, environment and ecology that China is facing. The project takes the logistics industry as the object to establish an evaluation model of logistics industry carbon emission efficiency and obtain the evaluation results of logistics industry carbon emission in 2014-2019. The carbon utilization efficiency of the system is calculated by slacks-based measurement (SBM) method. On this basis, Arc-Map software is used to conduct spatial modelling of empirical analysis is carried out. Through the research on the Beijing-Tianjin-Hebei region, we will further improve the ambitious strategic plan of ?carbon reduction, carbon neutrality? and contribute to the country?s economic and social development.
