Renewable　energy　generation,as　part　of　the　global　effort　to　mitigate　climate　change,will　play　a　central　role　in　reducing　greenhouse　gas　emissions　and　achieving　China＇s　goal　of　carbon　emissions　peak　before　2030　and　carbon　neutral　before　2060.However,the　impact　of　carbon　quota　auctions　on　renewable　energy　generation　has　not　been　sufficiently　discussed.The　main　purpose　of　this　study　is　to　investigate　whether　China　can　rely　on　quota　auctions　to　increase　renewable　energy　generation　in　the　short　term,and　to　demonstrate　which　is　more　effective　in　promoting　renewable　energy　development,policy　enforcement　or　auction　constraints?The　improved　neo-trans-log　production　model,the　multi-objective　linear　programming　model　and　the　dispatch　heuristic　were　used　to　predict　additional　emission　reduction　cost,optimized　power　mix　with　different　auctioning　rates,with　economic　development,technological　progress　and　the　unique　characteristics　of　China＇s　power　generation　industry　being　taken　into　consideration.The　results　show　that　the　auctioning　rate　will　have　little　influence　on　the　optimized　energy　production　structure,especially　on　the　share　of　renewable　energy　resources;when　the　total　on-grid　electricity　generation　ranges　from　7625　to　7926　billion　kW　h　and　the　auctioning　rate　ranges　from　0％　to　5％,policy　enforcement　will　influence　the　generation　of　renewable　energy　to　a　greater　extent　than　auctioning　in　the　near　future.
