This　study　focuses　on　exploring　the　spatial　and　temporal　evolution　characteristics　of　the　implied　carbon　emission　efficiency　of　Chinese　provinces　and　promoting　the　improvement　of　the　implied　carbon　emission　efficiency,　with　a　view　to　supply　reference　for　the　low-carbon　sustainable　development　of　China.　Based　on　the　data　of　each　province　onto　China　in　2007,　2012　and　2017,　this　study　applies　the　environmentally　extended　input-output　model　and　the　super-efficient　SBM　model　to　measure　the　implied　carbon　emission　efficiency　and　investigates　the　spatial　and　temporal　evolution　characteristics　of　the　implied　carbon　emission　efficiency　of　Chinese　provinces　through　kernel　density　estimation　and　ArcGIS　visualization.　The　results　show　that　the　implied　carbon　emission　efficiency　of　China＇s　provinces　and　regions　as　a　whole　increased　from　2007　to　2017,　and　that　differences　in　implied　carbon　emission　efficiency　between　provinces　and　regions　exist　and　are　gradually　increasing.　At　present,　China＇s　provincial　implied　carbon　emission　efficiency　is　still　at　a　low　level,　and　the　level　of　implied　carbon　emission　efficiency　varies　significantly　between　regions.　Overall,　from　2007　to　2017,　the　overall　carbon　emission　efficiency　in　China　has　been　considerably　improved.　©　The　Institution　of　Engineering　&　Technology　2023.
