工业企业节能量是对工业企业节能工作成效考核的重要指标,是全省节能考核监察体系的重要组成部分。本文以河北省工业企业节能量计算方法为研究目的,比较了现行几种计算方法的优劣,提出了单位工业产值能耗结构法计算工业企业节能量的新方法。本计算方法在考察工业企业单位产值能耗变化的基础上,同时考察该企业工业总产值比重变化对本地结构节能的影响,工业企业节能量是由企业直接节能和结构节能之和构成。通过对唐山市6家企业的实证计算和分析,按单位工业产值能耗结构法计算工业企业节能量有利于全面、客观评价工业企业节能工作,有利于提高政府节能考核指标和企业节能考核指标的衔接性,有利于提高节能考核工作的科学性和导向性。
Energy-saving industrial enterprises is an important indicator of the effectiveness of energy-saving industrial enterprises assessment is the province’s energy-saving inspection and supervision system is an important part. Based on the calculation method of energy saving of industrial enterprises in Hebei Province, this paper compares the advantages and disadvantages of several existing calculation methods, and puts forward a new method to calculate the energy-saving of industrial enterprises based on unit industrial output energy structure method. Based on the investigation of energy consumption per unit of output of industrial enterprises, this calculation method examines the impact of changes in the proportion of total industrial output value on the energy saving of local structures. The energy saving of industrial enterprises is composed of the direct energy saving of enterprises and the energy saving of structures. Through the empirical calculation and analysis of six enterprises in Tangshan City, calculating the energy-saving amount of industrial enterprises according to the energy consumption structure per unit industrial output is conducive to a comprehensive and objective evaluation of energy-saving work of industrial enterprises, which is conducive to raising the government energy-saving assessment index and enterprise energy-saving assessment index Convergence, is conducive to improving the energy-saving assessment of scientific and guiding.
