As　a　big　country　of　exports　trade,　China＇s　carbon　dioxide　emission　embodied　in　exports　is　considerable,　and　its　regional　difference　is　significant.　The　paper　chooses　nineteen　provinces　(municipality　city　and　autonomous　region)　to　evaluate　their　carbon　dioxide　emission　embodied　in　exports　using　input-output　analysis.　Results　show　that　regional　difference　of　carbon　dioxide　emission　embodied　in　exports　is　significant,　and　its　basic　character　is　carbon　dioxide　emission　embodied　in　exports　of　east　is　higher　than　west.　The　paper　chooses　Liaoning　and　Ningxia　as　cases,　using　structural　decomposition　analysis　model　to　decompose　their　difference　of　carbon　dioxide　emission　embodied　in　exports.　The　difference　of　carbon　dioxide　emission　embodied　in　exports　is　decomposed　into　four　parts:　direct　carbon　dioxide　intensity　difference,　intermediate　technology　difference,　exports　volume　and　structure　difference.　Results　indicate　that　their　contribution　value　is-589.60　ten　thousand　ton,-316.04　ten　thousand　ton,5947.99　ten　thousand　ton　and　-344.94　ten　thousand　ton　respectively.　So　carbon　dioxide　emission　embodied　in　exports　of　Liaoning　is　more　than　that　of　Ningxia　because　of　their　exports　volume　difference.　Direct　carbon　dioxide　intensity,　intermediate　technology　difference　and　exports　structure　effect　are　factors　to　promote　carbon　dioxide　emission　embodied　in　exports　of　Liaoning　is　less　than　Ningxia,　but　their　effect　is　smaller　than　exports　volume　effect.　So　the　main　reason　of　China＇s　carbon　dioxide　emission　regional　difference　is　exports　volume.
