【摘要】：文章利用多层次LMDI方法,分解2002—2013年安徽省工业用水强度变化的影响因素。研究发现:(1)规模以上工业及其部门用水强度总体呈现下降趋势,而规模以下工业用水强度远远高于规模以上工业,并且居高不下;(2)规模结构效应、部门结构效应和行业结构效应对工业用水强度的下降起到正向促进作用,而技术进步效应阻碍了工业用水强度下降,主要由于规模以下工业用水强度太高,拉高了工业用水强度,但是规模以上工业的技术进步效应有利于工业用水强度的下降;(3)规模以上工业技术进步效应反转是规模以上工业用水强度出现反转的主要原因,除水的生产和供应业之外,剩下36个行业的用水强度全部下降,对工业用水效率的提高具有明显的效果。
[Abstract]:In this paper, the factors influencing the change of industrial water use intensity in Anhui Province from 2002 to 2013 are analyzed by using multilevel LMDI method. The study found that the water intensity of industries above scale and its departments showed a downward trend in general, while the intensity of water use in industries below scale was much higher than that in industries above scale, and remained high in scale structure effect. Sector structure effect and industry structure effect play a positive role in promoting the decline of industrial water intensity, while technological progress effect hinders the decline of industrial water intensity, mainly because the intensity of industrial water use below scale is too high. The industrial water use intensity is increased, but the technological progress effect of the industry above the scale is favorable to the decrease of the industrial water use intensity.) the reversal of the industrial technological progress effect above the scale is the main reason for the industrial water intensity inversion above the scale. Except for the production and supply of water, the intensity of water use in the remaining 36 industries all decreased, which has obvious effect on the improvement of the efficiency of industrial water use.
