Under　the　coordinated　development　demands　of　climate　change,　carbon　emission　reduction,　energy　demand　and　economic　progress,　it　is　desired　to　methodically　study　the　compound　effects　of　the　joint　implementation　of　different　policies,　especially　the　detailed　impact　of　the　hierarchical　carbon-mitigation　(HCM)　policy.　A　multilevel　factorial　enviro-economic　equilibrium　(MFEEE)　model　is　developed　to　i)　explore　the　multi-level　interactive　effects　among　carbon　policy,　income　tax　and　production　tax　on　social-economic　and　environmental　(SEE)　systems;　ii)　access　the　effectiveness　of　hierarchical　carbon-mitigation　(HCM)　policy　among　socio-economic　sectors.　MFEEE　is　based　on　a　static　computable　general　equilibrium　(CGE)　model　using　2017　as　the　base　year.　The　results　indicated　that　HCM　policy　could　be　regarded　as　an　effective　measure　to　make　a　greater　contribution　to　related　SEE　issues　compared　with　the　non-hierarchical　policy.　The　interactive　effects　of　carbon　policy,　income　tax　and　production　tax　require　full　attention.　As　the　intensity　of　the　HCM　policy　increases,　the　contribution　of　the　interaction　between　carbon　policy　and　production　tax　becomes　more　significant.　The　impact　of　HCM　on　system＇s　GDP　may　be　greater　when　the　sectoral　differences　are　given　greater　attention　in　tiered　tax　rate.　These　findings　suggest　that　a　sectoral　differentiated　hierarchical　carbon-mitigation　policy　can　achieve　significant　emissions　reductions　with　minimal　economic　disruption.　Policymakers　should　consider　balancing　carbon　tax　structures　to　mitigate　adverse　effects　on　economic　growth　while　maximizing　environmental　benefits.
