To　explore　the　relationship　between　consumption　upgrading　and　agricultural　green　total　factor　productivity　in　the　context　of　green　and　high-quality　development　of　agriculture　in　China.　Based　on　the　construction　of　a　composite　index　of　consumption　upgrading　and　the　Malmquist　index　of　non-expected　output　in　the　SBM-DEA　model　to　measure　agricultural　green　total　factor　productivity,　this　paper　uses　the　PVAR　model　and　panel　data　from　30　Chinese　provinces　from　2008　to　2020　to　empirically　analyze　the　mechanism　of　the　effect　of　consumption　upgrading　on　agricultural　green　total　factor　productivity　under　high-quality　development.　The　results　are　as　follows:　(1)　Both　the　real　economy　and　consumption　upgrading　are　ahead　of　the　change　in　agricultural　green　total　factor　productivity　and　have　a　negative　short-run　impact　on　agricultural　green　total　factor　productivity　but　a　continuous　boosting　effect　in　the　long-run.　(2)　In　terms　of　specific　impact　paths,　the　real　economy　boosts　agricultural　green　total　factor　productivity　through　technical　efficiency　and　technical　change　paths　and　has　a　negative　impact　through　scale　efficiency,　whereas　consumption　upgrading　has　inhibitory　and　sustained　promotional　effects　in　the　short-　and　long-run,　respectively,　through　technical　efficiency　and　technical　change　paths　and　has　opposite　impact　effects　in　the　scale　efficiency　path.
