重庆市规模以上工业企业能耗的结构性分析

针对已有相关研究中地域针对性较弱的现状,以及工业节能在重庆节能减排工作中的重要地位,基于2004—2011年统计年鉴中重庆市规模以上工业企业产值能耗和增加值能耗的相关数据,采用"单位GDP能耗因素的数学分解方法"进行数据分析,将工业节能总量分解为一级结构节能量、二级结构节能量以及技术节能量,并讨论各因素的变动趋势和对节能总量的贡献程度,得到关于影响能耗变动的决定性因素的结论:首先是技术因素,其次是二级结构因素。同时,经过纵向比较,发现重庆工业技术性节能进入瓶颈的问题,并针对这一问题提出建议。

The Structural Analysis of Above Designated Size Industry Energy Consumption in Chongqing

For the lack of regional correlative research and the dominant place of industry energy consumption in Chongqing＇ s energy conservation, and based on the data of above designated size industry from 2004 to 2011, this article followed the ＂mathematical decomposition method of energy consumption per unit GDP＂, decomposed the change in in- dustry energy consumption per unit output value and per unit value added into the 1 st and the 2nd structural and technical components, and compared the changes and contribution rates of the 3 components, revealing that the most critical factor is technology, and 2nd structure in the next place. Finally, we put forward suggestions accordingly on the bottleneck problem of technical energy conservation aroused in longitudinal comparison.
