As global climate change intensifies,the assessment and improvement of carbon emission effi-ciency in the transportation industry have attracted increasing attention.This study comprehensively e-valuates the carbon emission efficiency of the transportation industry in 30 provincial-level administrative regions in China from 2012 to 2019 by using the Super-SBM model combined with undesirable outputs. Based on this,the Malmquist Productivity Index and its decomposition method are employed to reveal the changing trends in carbon emission efficiency among different regions in the transportation industry. The research findings provide scientific evidence for strengthening environmental protection measures and promoting carbon emissions reduction in provincial-level transportation industries,thereby offering important references for policymakers.
