It　is　of　great　significance　to　reasonably　evaluate　the　environmental　efficiency　of　the　transportation　industry,　because　it　is　related　to　the　transportation　industry＇　s　sustainable　development　of　green　and　low-carbon.　Based　on　data　envelopment　analysis　with　undesirable　outputs,　the　environmental　efficiency　of　China＇　s　regional　transportation　industry　is　evaluated;　and　combining　with　Meta-frontier　Malmquist　index　analysis,　the　dynamic　changes　in　its　environmental　efficiency　during　2007-2016　is　analyzed　from　the　perspective　of　regional　technical　differences.　The　results　show　that　the　environmental　efficiency　of　China＇s　transportation　industry　is　growing　slowly　on　the　whole,　and　there　is　still　much　room　for　improvement.　Meanwhile,　due　to　the　influence　of　regional　technological　differences,　the　transportation　industries　in　the　eastern,　central　and　western　areas　of　China　have　different　advantages　and　disadvantages　in　terms　of　environmental　efficiency.　On　this　basis,　the　corresponding　policy　suggestions　are　proposed　in　this　paper　to　help　all　regions　improve　their　environmental　efficiency　of　transportation　industry.　Copyright　©　2018　by　Science　Press.
