Increasing　the　market　penetration　of　electric　vehicles　(EVs)　is　an　important　step　toward　reducing　carbon　emissions　in　transport　and　achieving　the　＇double　carbon＇　target.　Currently,　the　public　acceptance　of　EV　is　significantly　low　in　China;　thus,　EVs　have　not　yet　become　the　mainstream　of　the　new　vehicles　sold.　Based　on　online　review　sentiment　analysis,　we　investigated　the　public＇s　perception　of　EV　attributes,　and　their　impact　on　Chinese　EV　sales.　The　public　comments　on　the　EV　attributes　of　four　brands-Volkswagen,　NIO,　Xiaopeng,　and　BYD-were　obtained　from　Autohome　and　analyzed　for　sentiment,　with　the　sentiment　scores　of　the　corresponding　attributes　as　the　independent　variables　and　the　monthly　sales　of　EV　during　2019-2021　as　the　dependent　vari-　ables.　A　fixed-effects　regression　model　with　panel　data　was　constructed　to　analyze　the　relationship　between　the　public　perceptions　of　EV　attributes　and　EV　sales.　Considering　the　trend　of　Chinese　government　subsidies　for　EV　in　recent　years,　a　moderating　effect　model　was　constructed　with　government　subsidy　policy　as　the　moderating　variable,　sentiment　perception　as　the　independent　variable,　and　EV　sales　as　the　dependent　variable.　The　results　of　the　study　showed　that　the　public　perception　of　the　four　attributes　of　EVs-comfort,　manipulation,　space,　and　cost　performance-　significantly　impact　EV　sales.　The　subsidy　policy　moderates　the　relationship　between　the　public＇s　perception　of　EV　attributes　and　EV　sales.　The　results　of　this　study　also　reflect　that　the　public　is　more　concerned　with　the　four　attributes　of　comfort,　manipulation,　space,　and　cost　performance　when　purchasing　EVs.　From　a　practical　perspective,　by　understanding　the　public　perception　of　EV　attributes,　government　policy　makers　and　EV　marketers　can　appropriately　adjust　and　change　their　existing　policies　and　marketing　strategies　for　promoting　EVs.
