Charging　infrastructure　supports　the　rapid　development　of　China＇s　new　energy　vehicle　industry.　It　not　only　plays　a　decisive　role　in　providing　accessible　and　convenient　services　for　electric　vehicle　(EV)　users　but　also,　in　one　of　the　seven　new　infrastructure　areas,　plays　an　important　role　in　stabilizing　growth　and　unleashing　economic　potential　during　the　new　coronavirus　(COVID-19)　pandemic,　impacting　China＇s　economy.　In　this　study,　the　system　dynamics　model　was　used　to　predict　the　development　of　the　EV　industry　and　the　demand　for　charging　infrastructure,　while　considering　the　influence　of　policy,　increase　in　EV　mileage,　and　consumer　purchase　intention　index.　Furthermore,　using　the　matching　of　EVs　and　charging　infrastructure　in　Beijing　and　policy-oriented　sensitivity　analysis,　a　simulation　of　the　construction　of　battery　swap　taxis　and　power　stations　under　three　policy　scenarios　was　conducted.　This　research　shows　that　with　policies　implemented　to　support　charging　infrastructure　and　swapping　compatible　taxis,　Beijing　can　achieve　its　goal　of　replacing　all　EVs　with　fast-swap　batteries　and　fast-charging　functions　within　three　years.　©　2022　The　Authors
