Abstract:An evaluation index system for regional carbon reduction ability was constructed from five aspects of carbon reduction factors. By applying the comprehensive evaluation model based on entropy value method, the states of carbon reduction ability of Beijing-Tianjin-Hebei from 2001 to 2011 were analyzed, and based on results we proposed the cooperation carbon reduction strategy of .Beijing-Tianjin-Hebei. The results shows that :(1)carbon reduction ability comprehensive ranking: Beijing > Tianjin> Hebei, Beijing"s economic development, technology, and carbon sequestration ability was significantly higher than that of Tianjin-Hebei, its per capita GDP, regional (R D) funds investment intensity and the third industry had great advantage to boost GDP than Tianjin-Hebei;(2)Regional carbon reduction ability of Beijing-Tianjin-Hebei had formed basically the gradient difference, and the main factors of regional cooperation carbon emissions was in Hebei province;(3)To reduce carbon emissions across the regions, Beijing-Tianjin-Hebei should carry out carbon reduction cooperation in the system, industry and technology, carbon sequestration and carbon trading mechanism.
