City　has　always　been　a　concentrated　area　of　consumption　and　pollution　in　a　country　or　region.　Solutions　to　the　dematerialization　of　city　would　exert　a　profound　impact　on　the　entire　socio-economic　system.　And　the　issue　of　resources　and　environment　in　Beijing,　the　center　of　China＇s　politics,　economy,　and　culture,　becomes　a　focus　of　attention　both　domestically　and　internationally.　In　this　paper,　we　used　the　economy-wide　material　flow　analysis　to　describe　the　socio-economic　development　and　the　current　situation　of　resources　and　environment　in　Beijing　during　the　period　1992-2015.　Based　on　this,　Tapio　decoupling　model　and　the　logarithmic　mean　divisia　index　method　were　used　to　analyze　the　level　and　influencing　factors　of　dematerialization　in　Beijing.　The　results　of　the　study　showed　that:　From　1992　to　2015,　GDP　of　Beijing　increased　from　61.25　billion　yuan　to　623.45　billion　yuan,　at　the　same　time,　direct　material　input　and　domestic　processed　output　also　increased　from　139.88　million　tons　and　78.63　million　tons　in　1992　to　205.17　million　tons　and　166.27　million　tons　in　2015　respectively.　Judging　from　the　change　of　the　decoupling　relationship　between　economic　growth　and　resources　and　environment,　the　level　of　dematerialization　in　Beijing　was　continuously　increasing.　And　the　dematerialization　level　of　resource　consumption　was　slightly　better　than　that　of　pollution　discharge.　The　high　expansion　of　population　and　economy　was　not　conducive　to　the　realization　of　dematerialization　in　Beijing.　However,　the　decrease　of　the　intensity　of　material　utilization　played　a　crucial　role　in　the　process　of　dematerialization　in　Beijing.　Moreover,　increases　in　material　circulation　and　social　overall　level　of　cleaner　production　were　beneficial　to　the　realization　of　dematerialization.　(C)　2018　Elsevier　Ltd.　All　rights　reserved.
