In　the　context　of　carbon　neutrality,　carbon-negative　technology　is　considered　a　crucial　technology　for　reducing　carbon　emissions　and　achieving　carbon　neutrality.　Carbon-negative　technology　has　gained　attention　from　governments,　businesses　and　academia.　To　comprehend　the　overall　development　status　of　carbon-negative　technology,　including　the　core　technologies,　the　patent　landscape,　competition,　and　cooperation　among　major　countries　and　regions,　this　paper　proposes　an　analytical　framework　for　the　patent　landscape　of　carbon-negative　technology.　The　research　results　demonstrate　the　rapid　overall　development　of　carbon-negative　technology.　The　R&D　strategies　of　major　competing　countries　in　the　field　of　carbon-negative　technology　focus　on　specific　technology　areas,　and　their　core　technologies　exhibit　similarities　as　well　as　differences.　In　the　field　of　technology-　based　solutions,　the　United　States　and　China　dominate　with　their　leaders　and　active　contributors　in　various　technology　domains.　The　collaboration　largely　revolves　around　the　United　States,　while　other　nations　engage　in　less　partnership　and　interaction.　Countries　have　not　yet　established　technological　leadership　in　carbon　sinks　technology,　and　the　cooperation　network　is　relatively　limited.　These　findings　contribute　to　our　understanding　of　the　current　global　development　status　of　carbon-negative　technology,　as　well　as　the　competitive　levels　and　positions　of　major　countries　in　this　field.　These　findings　also　provide　a　decision-making　basis　and　support　for　the　development　of　carbon-negative　technology.
