It’s　difficult　to　guarantee　the　effect　of　the　source　classification　of　domestic　waste　only　by　government,　so　it’s　necessary　to　rely　on　the　participation　of　residents,　social　organizations　and　other　forces.　In　this　paper,　by　constructing　the　evolutionary　game　model　of　government,　residents　and　social　organizations,　studies　the　evolutionary　stability　strategy,　and　uses　matlab　for　simulation　analysis.　The　results　show　that　(1)　When　government　loosely　supervises　and　residents　don’t　participate　in　the　classification,　the　frequency　of　participation　of　social　organizations　is　not　high,　which　is　not　conducive　to　the　classification　of　waste　sources.　(2)　When　government　strictly　supervises　and　residents　do　not　participate　in　the　classification,　social　organizations　are　more　active　in　participating,　but　the　government’s　management　cost　is　too　high.　(3)　When　government　loosely　supervises　and　residents　participate　in　classification,　the　participation　rate　of　social　organizations　increases,　and　residents’　awareness　of　independent　participation　in　waste　classification　is　increased,　also　can　achieve　the　desired　objective　waste　classification.　(4)　When　government　strictly　supervises　and　residents　participate　in　classification,　social　organizations　participate　actively　at　the　highest　level,　this　form　of　positive　attitudes　by　all　three　parties　is　also　the　best　way　to　efficiently　carry　out　waste　classification　at　source.　©　2022　WITPress.　All　rights　reserved.
