参考已有节能减排相关研究,并根据指标数据筛选出能源消耗强度、效率与消费结构、资源减量投入、污染物治理与利用、经济效益4类共16个指标,利用密切值法对河北省2002～2009年节能减排效果的演化趋势进行了评价。结果表明,2002～2006年期间河北省节能减排工作效益呈逐年递增趋势,2007～2009年期间每年节能减排效益优于2002～2006年期间,但2008年综合效益最优,其次是2007年,再次是2009年,与河北省实际情况相符。
According to the existing researches on energy conservation and emission reduction, according to the index data, 16 indices of energy consumption intensity, efficiency and consumption structure, resource reduction investment, pollutant treatment and utilization, and economic benefits are screened out. Based on the close value method, The evolution trend of energy conservation and emission reduction effect in 2002-2009 was evaluated. The results show that the efficiency of energy conservation and emission reduction in Hebei Province has been increasing year by year from 2002 to 2006, and the annual energy saving and emission reduction benefits of 2007-2009 are better than those of 2002-2006, but the comprehensive efficiency is the best in 2008, followed by that of 2007 , Again in 2009, in line with the actual situation in Hebei Province.
