Driven　by　the　dual　carbon　target,　carbon　emission　management　and　carbon　allocation　among　counties　have　become　important　issues.　Taking　Zhejiang　province　as　an　example,　based　on　the　gravity　model　and　social　network　analysis,　the　internal　mechanism　of　carbon　factor　connection　among　counties　was　explained,　and　the　scale　restructuring　of　counties　was　carried　out　to　break　through　the　administrative　barriers　and　form　the　county　collaborative　carbon　governance　alliance.　Furthermore,　the　Shapley　value　method　was　used　to　construct　a　two-stage　model　for　completing　the　allocation　of　carbon　emission　rights　at　the　county　scale　from　2018　to　2030.　The　results　demonstrate　that　the　spatial　correlations　of　carbon　factors　among　counties　show　synergistic　characteristics,　such　as　high　linear　correlation,　central　cooperation,　and　multi-polarization　radiation,　which　lead　to　the　formation　of　ascending　power　and　responsibility　subjects　in　the　vertical　structure,　and　the　formation　of　twelve　cooperative　carbon　governance　alliances　among　counties　in　the　horizontal　structure.　Under　the　framework　of　cooperative　game,　the　spatial　differentiation　pattern　of　carbon　emission　rights　at　county　level　manifests　as:　Continuous　form　of　zonal　pattern,　multi-center　subordinate　structure　and　circular　recursive　texture.　Our　research　provides　a　reference　for　establishing　sustainable　county　carbon　management　strategy.　©　2023　Chinese　Medical　Association.　All　rights　reserved.
