Future　cities　prioritize　green　development　to　combat　climate　change,　focusing　on　reducing　energy　consumption,　exhaust　emissions,　and　traffic　congestion.　Shared　electric　vehicles　offer　eco-friendly　transportation,　improving　vehicle　utilization,　reducing　resource　waste,　and　mitigating　environmental　pollution　through　sharing.　Despite　these　benefits,　range　anxiety　and　inconvenience　hinder　widespread　adoption,　with　many　still　opting　for　taxis.　Currently,　most　taxis　worldwide　rely　on　traditional　fuel,　leading　to　high　fuel　consumption　and　unnecessary　carbon　emissions　and　waste　as　drivers　frequently　search　for　customers　on　the　roads.　Different　from　Shared　Charging　Electric　Vehicles　(SCEVs)　in　the　current　market,　this　paper　proposes　Shared　Battery-swapping　Electric　Vehicles　(SBEVs),　integrating　battery-swapping　technology　into　shared　electric　vehicles.　This　innovation　aims　to　enhance　convenience,　attracting　users　to　eco-friendly　transportation　and　reducing　reliance　on　traditional　fuel　taxis.　Hence　by　constructing　two　business　models　of　the　current　competitive　market　(Model　1)　and　the　future　competitive　market　(Model　2),　this　paper　analyzes　consumer　preferences　for　taxis　and　SCEVs　in　Model　1,　as　well　as　explores　the　conditions　for　encouraging　more　consumers　to　choose　SBEVs　over　taxis　by　improving　the　convenience　of　SBEVs　in　Model　2.　The　optimal　operational　decisions　of　supply　chain　participants　in　both　markets　are　obtained,　including　the　car-sharing　operator　determining　the　optimal　SCEV　usage　price　in　Model　1,　and　the　optimal　SBEV　usage　price　and　the　optimal　efforts　to　enhance　the　convenience　degree　of　SBEVs　by　installing　battery　swapping　infrastructure　in　Model　2.　This　study　provides　valuable　insights　for　driving　green　practices　and　operational　improvements　in　the　shared　electric　vehicle　sector.
