To　explore　the　impact　of　uncertain　technical　efficiency　on　the　decision-making　of　green　supply　chain　mem-bers,　a　supply　chain　model　consisting　of　technical　Service　Providers,　manufacturers　and　retailers　was　constructed.　The　results　showed　that:　©If　the　manufacturer　did　not　have　the　conditions　for　independent　innovation,　the　manufacturer　would　only　purchase　technology　when　the　R&-D　efficiency　was　high;　if　the　manufacturer　had　the　conditions　for　independent　innovation,　when　the　average　level　of　green　technology　and　R&-D　efficiency　were　low　or　moderate,　the　manufacturer　would　choose　to　purchase　technology,　otherwise　it　would　choose　independent　innovation;　moreover,　the　purchase　technology　strategy　could　better　cope　with　the　impact　of　uncertain　technical　efficiency　under　certain　conditions.　©　Under　the　independent　innovation　strategy,　the　improvement　of　the　average　level　of　green　technology　would　increase　the　green　level　of　manufacturers　and　have　a　positive　effect　on　manufacturers　and　retailers.　The　in-crease　of　green　technology　volatility　and　risk　aversion　would　have　a　negative　impact　on　manufacturers　and　retailers.　©Under　the　purchase　technology　strategy,　the　degree　of　risk　aversion,　the　average　level　and　volatility　of　green　technology　had　a　positive　impact　on　technology　Service　Providers　and　retailers,　but　might　have　a　negative　impact　on　manufacturers.　©　2025　CIMS.　All　rights　reserved.
