There　are　close　links　and　interactions　among　consumers＇　attitudes,　the　construction　of　charging　infrastructure,　and　the　diffusion　of　new　energy　vehicles　(NEVs).　This　study　focuses　on　consumers＇　sentient　attitudes　toward　charging　infrastructure　and　the　effect　of　consumer　attitudes　toward　the　construction　of　charging　piles　and　NEV　sales　using　natural　language　processing　technology　and　the　panel　vector　autoregressive　method.　Consumers＇　sentient　attitudes　(i.e.,　positive,　negative,　and　neutral)　were　inferred　by　analyzing　consumer　comments　on　charging　infrastructure　obtained　from　the　internet.　The　key　reasons　for　consumers＇　negative　attitudes　were　further　investigated,　and　the　diversity　in　their　attitudes　was　explored　at　the　city　level.　The　results　show　a　growing　concern　for　consumers　about　charging　infrastructure　since　2013.　The　overall　satisfaction　of　consumers　has　constantly　improved.　The　top　pain　points　that　cause　consumers＇　negative　attitudes　are　inconvenient　charging,　charging　dilemmas,　inability　to　install　private　charging　piles,　etc.　Consumers＇　negative　attitudes　have　a　significantly　positive　impact　on　the　charging　piles＇　construction.　It　also　has　a　significantly　negative　impact　on　the　sales　of　NEVs,　but　the　effects　are　themselves　short-term.　Usually,　the　impact　of　negative　attitudes　is　stronger　than　that　of　positive　attitudes.
