节能低碳视角下的我国工业行业效率
发布时间：2018-12-26 06:39
【摘要】：采用基于方向距离函数的非参数方法,从节能低碳的视角测算了我国2007—2013年36个工业行业的效率,并分析了效率的时序特性和行业异质性。研究发现,除2008年略低外,各年工业行业效率均值大致相同,后5年略有上升,但不明显;能耗较高的行业效率值与能耗较低的行业效率值有明显差异,但碳排放量大的行业与碳排放量小的行业效率差异不明显;大部分行业效率水平不高,尤其高能耗行业,节能降碳潜力较大。
[Abstract]:Based on the nonparametric method of directional distance function, the efficiency of 36 industrial industries in China from 2007 to 2013 is calculated from the perspective of energy saving and low carbon. The temporal characteristics and industry heterogeneity of efficiency are analyzed. The study found that except for the low level in 2008, the average efficiency of the industrial industry was about the same in each year, and increased slightly in the latter five years, but it was not obvious. The efficiency of industries with higher energy consumption is significantly different from that of industries with lower energy consumption, but there is no significant difference in efficiency between industries with large carbon emissions and industries with low carbon emissions. The efficiency level of most industries is not high, especially high energy consumption industries, energy saving and carbon reduction potential.
