Efficiency Evaluation of Logistics Industry in the Beijing-Tianjin-Hebei Region under Low-Carbon Constraints Based on the DEA-Malmquist Model

This paper studies the logistics efficiency of the Beijing-Tianjin-Hebei region under the background of low-carbon economy from 2012 to 2017. We introduce the carbon dioxide emission into the input indicators on the basis of the pollutant input method, and we use the BCC model and Malmquist index model to make both static and dynamic efficiency evaluations of logistics industry. Also, we use the projection analysis method to analyze the root causes of DMUs with non-DEA efficiency. According to the problems of logistics efficiency in Beijing-Tianjin-Hebei region, we put forward some recommendations to help the whole region achieve collaborative development under the low-carbon environment
