This paper used super-SBM model that considered undesired output, taking 13 cities in the Beijing-Tianjin-Hebei region as samples, and selecting panel data from 2008 to 2017 to measure the overall efficiency of energy-saving and emission-reducing in the Beijing-Tianjin-Hebei urban agglomeration. Decomposition and analysis of the comprehensive efficiency was performed through the Malmquist index model. The results showed that the overall efficiency of energy-saving and emission-reducing in the Beijing-Tianjin-Hebei urban agglomeration was generally low and fluctuating, showing the spatial pattern of the overall efficiency of energy-saving and emission-reducing has changed significantly, and the space radiation effect of high-efficiency cities was weak. TFPC fluctuated significantly, and TC was its main driving factor, PTEC and SEC jointly restricted the improvement of TEC.
