This　paper　investigates　the　development　trends　and　variation　characteristics　of　China＇s　economy,　energy　consumption　and　carbon　emissions　from　2007　to　2030,　and　the　impacts　on　China＇s　economic　growth,　energy　consumption,　and　carbon　emissions　under　the　carbon　tax　policy　scenarios,　based　on　the　dynamic　computable　general　equilibrium　(CGE)　model.　The　results　show　that　during　the　simulation　period,　China＇s　economy　will　keep　a　relatively　high　growth　rate,　but　the　growth　rate　will　slow　down　under　the　benchmark　scenario.　The　energy　consumption　intensity　and　the　carbon　emissions　intensity　per　unit　of　Gross　Domestic　Product　(GDP)　will　continually　decrease.　The　energy　consumption　structure　and　industrial　structure　will　gradually　optimize.　With　the　economic　growth,　the　total　energy　consumption　will　constantly　increase,　and　the　carbon　dioxide　emissions　are　still　large,　and　the　situation　of　energy-saving　and　emission-reduction　is　still　serious.　The　carbon　tax　is　very　important　for　energy-saving　and　emission-reduction　and　energy　consumption　structure　optimization,　and　the　effect　of　the　carbon　tax　on　GDP　is　small.　If　the　carbon　tax　could　be　levied　and　the　enterprise　income　tax　could　be　reduced　at　the　same　time,　the　dual　goals　of　reducing　energy　consumption　and　carbon　emissions　and　increasing　the　GDP　growth　can　be　achieved.　Improving　the　technical　progress　level　of　clean　power　while　implementing　a　carbon　tax　policy　is　very　meaningful　to　optimize　energy　consumption　structure　and　reduce　the　carbon　emissions,　but　it　has　some　offsetting　effect　to　reduce　energy　consumption.
