河南省工业用水量变化驱动因素及回弹效应研究
Research on Driving Factors and Rebound Effect of Industrial Water Use Change of Henan Province
摘要
Abstract
With the advancement of water-saving technologies,China's industrial water use efficiency has been continuously improved,and the total industrial water use has shown a downward trend.The LMDI model was applied to analyze the driving factors of changes in industrial water use,and the rebound effect was used to quantitatively analyze the actual offset degree of the effectiveness of technological water-saving measures.An empirical analysis of the long-series panel data of Henan Province and its 18 prefecture-level cities from 2014 to 2022 shows that the improvement of industrial water use efficiency has effectively reduced the industrial water use,with the role of this factor being signif-icantly enhanced.Meanwhile,economic scale and industrial structure have also contributed to a significant reduction in industrial water use,though there are large differences in their driving directions across different years and prefecture-level cities.On the whole,industrial water use in Henan Province is in a state of partial rebound effect.Driven by technological progress,the rebound effect value has decreased year by year,and the decoupling phenomenon between industrial water use and industrial added value has become obvious since 2019.Additionally,industrial water use in all 18 provincial-level cities also experience partial rebound,but there are significant regional differences(the rebound effect is relatively low in Xuchang,Pingdingshan and Kaifeng,while it is higher in Luohe,Anyang and Jiyuan).In order to alleviate the pressure of water resources shortage,reduce water environmental pollution and improve the level of industrial water conservation,controlling the rebound effect of industrial water use is essential.In order to achieve the high-quality development of Henan's industrial economy,sug-gestions are put forward,including continuing to promote the improvement of industrial water use efficiency,coordinately advancing the for-mulation of industrial policies and water-saving policies,and building a regionally differentiated collaborative governance system.关键词
