Copper＇s　multi-life　cycle　recycling　ensures　sustainable　copper　supply　but　has　brought　about　complex　interrelated　effects　on　the　economy,　resources,　and　environment.　Examining　the　interconnections　between　the　three　to　promote　balance　is　crucial　for　the　long-term　sustainability　of　the　copper　industry.　This　study　jointly　utilized　system　dynamics,　agent-based　model,　and　life　cycle　assessment　to　construct　interrelated　pathways　for　the　economy,　resources,　and　carbon　in　multi-life　cycle　recycling　of　copper,　then　developed　an　economic-resource-carbon　(ERC)　sustainability　assessment　model　to　evaluate　sustainability.　The　results　indicate　that　carbon　neutrality　will　lead　to　sustained　growth　in　China＇s　copper　demand,　which　will　reach　a　peak　of　24.65　Mt　in　2039　before　slightly　declining.　Multi-life　cycle　recycling　will　rapidly　increase　the　share　of　recycled　copper,　and　the　copper　industry　will　have　the　copper　that　has　been　recycled　12　times　by　2050.　The　cumulative　contributions　of　profit　increase,　resource　depletion　reduction,　and　carbon　reduction　brought　by　multi-life　cycle　recycling　will　accumulate　with　the　increase　of　recycling　times,　thereby　improving　the　ERC　sustainability.　To　promote　the　longterm　sustainability　of　the　copper　industry,　we　recommend　fully　leveraging　the　advantages　of　new　material　substitution　before　2030,　implementing　a　carbon　tax　as　soon　as　possible　after　2030,　and　recognizing　the　potential　of　expanding　copper　concentrate　imports　after　2040　while　enforcing　the　carbon　tax　policy.
