There　is　a　general　phenomenon　of　incoordination　between　garbage　classification　management　and　participation　behavior,　which　seriously　affects　the　sustainable　management　efficiency　of　domestic　garbage.　In　order　to　solve　this　problem,　this　paper　introduced　the　subject-object-process　model　into　the　waste　classification　management　system,　and　constructed　a　mandatory　classification　management　model　of　municipal　solid　waste　and　a　comprehensive　evaluation　index　system.　Taking　Beijing,　China,　as　an　example,　the　coupling　coordination　degree　of　garbage　classification　behaviors　of　residents　in　different　was　compared,　and　the　coordination　status　of　household　waste　management　and　behaviors　was　obtained.　The　results　show　that　the　synergy　between　government　management　and　residents＇　household　waste　classification　behavior　is　between　0.40　and　0.68,　and　the　synergy　between　enterprises＇　participation　in　governance　and　residents＇　behavior　is　between　0.45　and　0.75.　The　coordination　degree　between　domestic　waste　management　and　residents＇　participation　behavior　is　generally　in　primary　coordination　or　slight　imbalance.　The　synergy　degree　between　the　secondary　indicators　of　domestic　waste　management　and　residents＇　behavior　is　higher　than　that　of　the　tertiary　indicators.　Superposition　effect　of　integrated　management　measures　is　better;　among　the　psychological　factors　affecting　residents＇　classification　behavior,　the　awareness　rate　and　recognition　degree　of　waste　classification　are　very　high,　the　awareness　of　environmental　responsibility　and　social　pressure　are　lagging　behind.　The　study　of　synergy　under　the　framework　of　subject-object-process　not　only　quantifies　the　overall　synergy　between　management　and　residents＇　behavior,　but　also　provides　a　method　to　further　implement　garbage　classification　management　in　a　targeted　manner.　Based　on　the　synergy　analysis,　according　to　the　weak　links　of　various　regions,　classified　management　is　carried　out　around　publicity　and　education,　supervision　and　management,　assessment,　rewards　and　punishments.
