This　paper　employs　the　DEA　method　to　measure　energy　use　efficiency　in　Chinese　provinces　from　the　perspective　of　energy-saving　and　emission-reduction.　Concretely,　an　index　that　reflects　energy-saving　and　emission-reduction　is　introduced　to　analyze　a　cross-section　of　data　that　cover　30　provinces　in　China.　This　index　is　more　instructive　in　showing　a　measure　of　energy　usage　in　different　provinces,　compared　to　a　method　that　does　not　use　this　type　of　index.　This　method　gives　a　different　outcome　compared　to　the　previous　method　for　Beijing,　Hainan　and　Qinghai.　This　conclusion　is　an　important　reference　for　the　measurement　of　the　actual　result　of　the　practice　of　energy-saving　and　emission-reduction　in　China,　and　this　method　may　be　preferable　by　providing　us　with　additional　insights.　©　2008　IEEE.
