Clarifying　the　evolution　of　the　co-opetitive　relationships　among　stakeholders　of　the　symbiosis　network　for　＇urban　mineral＇　utilization　has　great　significance　in　enhancing　the　efficiency　of　resource　utilization.　Based　on　the　perspective　of　reverse　supply　chain　and　reverse　supply　chain　competition,　six　sets　of　modes　under　different　government　subsidy　conditions　and　different　channel　structure　are　constructed.　By　comparing　the　equilibrium　outcomes　of　various　cooperation　modes,　the　paper　examines　the　paths　of　vertical　structure　strategies.　After　that,　this　paper　explores　how　horizontal　stakeholder　relationships　influence　vertical　cooperative-competitive　behaviors.　And　the　stability　of　the　conclusions　are　validated　through　a　series　of　extended　mode　analysis　and　numerical　simulation.　Our　results　show　that,　1)　The　symbiosis　network　will　maximize　the　economic,　environmental　and　social　value　of　＇urban　mineral＇　utilization　when　both　chain　choose　the　centralized　decision　structure;　2)　Regarding　dominant　strategies,　it’s　possible　for　both　supply　chains　to　adopt　either　a　centralized　or　decentralized　decision　mode　as　an　equilibrium　strategy.　This　is　because　horizontal　competition　among　recyclers　can　affect　the　degree　of　symbiosis　with　upstream　remanufacturers,　thus　influencing　the　overall　supply　chain　profit　and　the　choice　of　vertical　channel　structure　strategy;　3)　Higher　levels　of　symbiosis　aren’t　always　better,　excessive　symbiosis　can　weaken　the　positive　externalities　of　a　centralized　decision　structure;　4)　Government　subsidy　policies　can　optimize　the　resource　utilization　efficiency　of　urban　minerals.　what’s　more,　subsidies　to　remanufacturers　rather　than　recyclers　are　more　likely　to　enhance　social　welfare.　However,　the　effectiveness　of　subsidy　policies　will　invalid　in　the　later　stages　of　symbiosis.　Therefore,　regulating　the　degree　of　competition　among　recyclers,　maintaining　the　degree　of　symbiosis　in　an　appropriate　range,　and　formulating　proper　incentive　policies　can　help　the　centralized　decision　structure　to　achieve　Pareto　improvements　of　the　overall　profit　of　the　supply　chain,　so　as　to　promote　the　symbiosis　from　a　competitive　relationship　to　a　stable　cooperation　state.　©　2025　Systems　Engineering　Society　of　China.　All　rights　reserved.
