Owing　to　the　convenience　and　price　advantages,　polyethylene　terephthalate　(PET)　bottles　have　been　widely　used　in　daily　life.　This　leads　to　a　substantial　number　of　waste　PET　bottles.　Because　of　the　lack　of　corresponding　management　policies　in　developing　countries,　PET　bottles　have　entered　the　informal　collection　and　recycling　sectors　in　large　quantities,　causing　serious　environmental　pollution.　In　China,　how　to　regulate　the　formal　collection　and　achieve　optimal　performance　of　a　PET　bottle　recycling　system　with　policy　implementation　methods　are　still　being　explored.　This　study　constructs　a　dynamic　recycling　system　of　waste　PET　bottles　for　the　production-consumption,　consumption-collection,　and　collection-recycling　subsystems　that　regulate　the　formal　recycling　of　PET　bottles　through　policies.　The　deposit-refund　system,　mandatory　policy　and　tax　refund　system　were　used　as　the　standard　recycling　policy　in　a　simulation,　and　comprehensive　performance　changes　were　compared　before　and　after　the　policy　simulation.　The　results　indicate　that　the　comprehensive　performance　(basic　scenario)　of　the　PET　bottle　recycling　system　is　an　average　of　5.42　billion　CNY.　With　the　policy　mix　scenario,　it　reached　to　6.51　billion　CNY,　and　the　formal　collection　rate　increased　to　55.8%.　Compared　with　the　basic　scenario,　the　comprehensive　performance　of　the　policy　mix　scheme　increased　by　20%,　which　is　beneficial　to　the　operations　of　the　formal　collection　and　recycling　sectors　and　increases　the　production　vitality　of　the　formal　PET　recycling　industry.
