With　the　introduction　of　＂dual　carbon　＂　goals　of　＂peaking　its　carbon　emissions　before　2030　and　achieving　carbon　neutrality　by　2060　＂　and　the　gradual　promotion　of　the　carbon　trading　market,　it　is　the　main　trend　to　achieve　low-carbon　and　clean　development　in　the　future.　It　is　of　great　practical　significance　to　effectively　measure　the　low-carbon　development　level　and　conduct　obstacle　degree　analysis.　Based　on　this,　this　article　aims　to　investigate　the　low-carbon　development　level　index　of　Fujian　province　from　2006　to　2019　by　using　the　entropy　weight　TOPSIS　model.　Then,　the　key　influencing　factors　are　explored　by　using　the　obstacle　degree　model.　The　results　show　that　the　low-carbon　development　level　index　of　Fujian　province　shows　a　fluctuating　upward　trend,　rising　from　0.164　in　2006　to　0.803　in　2019.　The　environmental　system　has　always　been　an　important　factor　affecting　the　low-carbon　development　in　Fujian　province,　with　an　average　annual　obstacle　degree　of　46.52%,　but　the　impact　of　the　other　three　subsystems　is　also　gradually　increasing.　Green　innovation,　energy　conservation,　air　pollution,　economic　development,　and　environmental　governance　are　the　top　five　indexes　with　the　highest　annual　obstacles.　Based　on　the　previous　results,　this　article　puts　forward　corresponding　policy　recommendations,　which　provide　theoretical　support　for　the　low-carbon　development　of　Fujian　province.
