Carbon　emissions　in　agricultural　production　activities　have　become　an　important　source　of　accelerating　climate　warming.　At　present,　low-carbon　agriculture　is　not　only　an　important　means　to　mitigate　climate　warming,　but　also　a　necessary　process　of　transformation　from　traditional　agriculture　to　modern　agriculture.　Therefore,　to　achieve　the　sustainable　development　of　agriculture　in　China’s　Western　Taiwan　Straits　Economic　Zone　(WTS　Economic　Zone),　the　governments　should　vigorously　promote　the　upgrading　and　realize　the　development　of　low-carbon　agriculture.　By　adopting　the　latest　emission　coefficients　and　the　ordered　weighted　averaging　(OWA)　aggregation　operator,　this　paper　selected　agricultural　land　use,　rice　paddies,　crop　production,　livestock　manure　storage　and　livestock　enteric　fermentation　as　the　five　carbon　emission　sources,　and　measured　agricultural　carbon　emissions　in　the　WTS　Economic　Zone　from　2010　to　2017.　Thus,　from　the　time　perspective,　the　average　agricultural　carbon　emissions　in　the　WTS　Economic　Zone　showed　a　fluctuating　downward　trend,　from　762.64　×　103　tonnes　in　2010　to　710.02　×　103　tonnes　in　2017.　From　the　spatial　perspective,　total　agricultural　carbon　emissions　among　regions　are　quite　different.　To　further　clarify　the　factors　affecting　agricultural　carbon　emissions　in　the　WTS　Economic　Zone,　by　applying　the　geographically　and　temporally　weighted　regression　(GTWR)　model,　this　paper　selected　the　research　and　development　intensity,　the　added　value　of　agriculture,　the　proportion　of　agricultural　labour　force,　the　overall　level　of　urbanization,　per　capita　disposable　income　of　rural　residents　and　per　capita　arable　land　areas　as　the　influencing　factors,　and　then　measured　the　direction　and　degree　of　the　influences　on　agricultural　carbon　emissions　in　different　temporal-spatial　backgrounds.　The　results　showed　that　the　added　value　of　agriculture,　the　proportion　of　agricultural　labour　force　and　per　capita　arable　land　areas　had　positive　influences　on　agricultural　carbon　emissions,　while　the　research　and　development　intensity,　the　overall　level　of　urbanization　and　per　capita　disposable　income　of　rural　residents　had　negative　impacts.　Although　agricultural　carbon　emissions　in　the　WTS　Economic　Zone　have　decreased　in　recent　years,　further　measures　can　be　taken　to　effectively　reduce　agricultural　carbon　emissions,　and　ultimately　promote　the　development　of　low-carbon　agriculture　according　to　the　results　of　this　study.　©　2020　Technoscience　Publications.　All　rights　reserved.
