As China's "Capital Economic Circle", the Beijing-Tianjin-Hebei region has an important strategic position. Carbon emission efficiency can be understood as the ratio of the unit of carbon emissions generated to the economic cost invested, and under normal conditions, carbon emission efficiency improvement means that the production cost is reduced while the carbon emission is kept unchanged or the existing production input base is maintained. Improving carbon efficiency is conducive to the sustainable development of the logistics industry. Based on the 2010-2020 panel data, this paper uses the emission coefficient method to calculate the carbon emissions of the logistics industry in the Beijing-Tianjin-Hebei region from 2010 to 2020, takes the carbon emission efficiency of the logistics industry in the Beijing-Tianjin-Hebei region as the evaluation index, constructs a super SBM model to measure the carbon emission efficiency of the logistics industry in the Beijing-Tianjin-Hebei region, and then evaluates and analyzes the carbon emission efficiency of the logistics industry in the Beijing-Tianjin-Hebei region. The results show that the overall carbon emission efficiency in the Beijing-Tianjin-Hebei region shows a slow upward trend, and there is more room for improvement, and finally according to the above conclusions, suggestions such as establishing green values, formulating reasonable policies and optimizing management systems are put forward.
