With　the　enhancement　of　consumer＇s　environmental　awareness,　environmental　knowledge　and　health　consciousness　attitude,　environment　friendly　product　and　services　have　attracted　much　attention.　The　main　objective　of　this　study　was　to　analyze　the　determinants　of　consumer＇s　adoption　intention　to　5G　services.　Value　adaptation　Model　(VAM)　model　was　extended　to　develop　a　correlational　model　by　adding　three　factors:　environmental　awareness,　environmental　knowledge,　and　health　consciousness　attitude　to　pay　for　5G　services.　The　model　was　tested　based　on　online　survey　data　from　423　respondents　in　China　applying　structural　equation　modelling　(SEM)　approach.　The　final　results　illustrate　the　significant　relationship　between　environmental　awareness,　knowledge　and　health-consciousness　attitude,　which　further　influences　consumer＇s　intentions　to　purchase　5G.　In　addition,　compared　with　previous　models,　this　model　can　improve　the　explained　variance.　The　significance　of　the　study　for　managers　and　researchers　and　some　limitations　are　also　discussed.　©　2021　Elsevier　Ltd
