The　electric　vehicle　(EV)　is　a　kind　of　innovation　helping　to　address　the　issue　of　climate　change　and　conventional　energy　consumption,　compared　to　internal　combustion　engine　vehicles.　Electric　vehicle　sharing　is　a　new　way　to　promote　the　market　penetration　of　electric　vehicles　due　to　its　convenience　and　economy.　Aiming　to　provide　a　more　profound　understanding　of　the　influential　factors　in　the　acceptance　of　electric　vehicle　sharing,　a　structural　equation　model　is　proposed　based　on　the　theory　of　planned　behavior　as　the　policy　environment　has　been　added　as　prepositive　variable.　The　data　about　the　travelers＇　perspective　of　electric　vehicle　sharing　are　acquired　from　questionnaires　in　Beijing.　The　results　indicate　that　the　perceived　behavioral　control　is　the　primary　factor　with　positive　contributions　to　EV-sharing　acceptance.　Subjective　norm,　ranking　second,　is　also　proven　to　exert　a　significant　positive　effect　on　EV-sharing　acceptance.　The　results　also　reveal　the　insignificant　relationship　between　the　attitude　towards　behavior　and　sharing　acceptance,　which　is　consistent　with　relevant　research.　Moreover,　the　significant　positive　effects　of　policy　support　on　attitude　and　subjective　norm　are　demonstrated.　Finally,　strategies　to　promote　electric　vehicle　sharing　are　proposed,　including　providing　more　accessible　resources　(charging　facility,　service　station),　improving　social　pressure　(free　trial,　sharing　atmosphere),　and　strengthening　policy　support　(financial　support,　legal　guarantee).　This　study　can　give　a　better　understanding　of　the　acceptance　of　EV　sharing　and　the　strategy　to　promoting　EV　sharing　in　urban　traffic.
