摘要:

为避免传统能源效率测算中的偏差,采用非径向的SBM方向距离函数对1996~2010年中国29个省市、自治区(西藏除外)在环境约束下的能源效率进行了测算,在此基础上,对“九五”至“十一五”期间全国及东部、东北、中部、西部各地区的能源效率差异进行了比较分析,并对无效率来源进行了分解。结果表明:尽管样本期间全国整体能源效率水平在不断提升,但仍存在一定的能源利用无效率,能源资源利用水平低、环境污染高排放是其中的主要原因;各地区间、区域间能源效率存在较大差异;对造成能源效率差异的原因进行分析发现除环境因素外,能源投入利用水平低是制约东北老工业基地和中部地区效率提升的主要瓶颈因素,而经济产出水平则制约了西部地区效率水平的提高,这为因地制宜的制定差异化节能减排政策提供了决策支持

Abstract:

Global awareness on energy security and climate change has created much interest in assessing economywide energy efficiency.A number of previous studies have contributed to evaluate energy efficiency using different analytical techniques,among which data envelopment analysis (DEA) has recently received increasing attention.Most of DEArelated energy efficiency studies do not consider undesirable outputs,which may lead to biased energy efficiency values.In order to calculate the value of the energy efficiency accurately,non radial SBM(Slackbased measure) directional distance function was used to evaluate the energy efficiency of 29 provinces (except Tibet) in China from 1996 to 2010 under the constraint of environment. In this research,energy,labor,and capital were chosen as the three inputs,while GDP as the good output,SO2 emission as a substitute variable for environmental effects of energy utilization.The analysis indicated that the efficiency of energy utilization improved from 0647 in the ninth fiveyear plan period to 0774 in the eleventh fiveyear plan period,while there was room for China to improve its energy efficiency.The low efficiency of energy utilization and the high emission of pollutants were the main contributors to low energy efficiency in China.Regional difference was also existed among different regions:the east area ranked the first with the highest efficiency value,the northeast and central area followed,and the west area had the lowest efficiency value.Furthermore,the main contributors to the low efficiency varied greatly from each other.The low efficiency of energy utilization was the main bottleneck factor that restricted the promotion of energy efficiency in the northeast and central regions,and the low economic output was the main reason that restricted the improvement of energy efficiency in the west region,without the consideration of pollution emission.Based on our findings,some policy implications on the improvement of energy efficiency for each region in China were disscused.
