摘　　要：采用LMDI方法,将中国生活用水量变化的影响因素分解为生活用水消费强度、消费占GDP比重、人均GDP、家庭规模和家庭数量,将人均生活用水量变化分解为生活用水消费强度、消费占GDP比重和人均GDP,分析发现,生活用水消费强度和家庭规模是抑制生活用水量增加的主要和次要因素,人均GDP和家庭数量是促进生活用水量增加的主要和次要因素,消费占GDP比重的促减效应和促增效应同时存在。生活消费用水强度、人均GDP以及消费占GDP比重对人均生活用水量和生活用水量的影响相同。因此,要实行高质量发展,形成节水型生活方式,提高用水效率;围绕家庭发展制定执行生活节水政策;提升全民节水意识,建立生活用水的先进定额体系。This research used the LMDI method to decompose the influencing factors of domestic water consumption changes into do⁃mestic water consumption intensity,the proportion of consumption in GDP,per capita GDP,household size and the number of house⁃holds,and decompose the change in per capita domestic water consumption into domestic water consumption intensity and consump⁃tion in GDP Proportion and GDP per capita.It was found that domestic water consumption intensity and household size were the main and secondary factors inhibiting the increase of domestic water consumption.Per capita GDP and the number of households were the main and secondary factors that promotd the increase in domestic water consumption.The reduction and growth effected of the propor⁃tion of consumption in GDP simultaneously exist.Domestic consumption water intensity,per capita GDP,and the proportion of con⁃sumption in GDP had the same impact on per capita domestic water consumption as that of domestic water consumption.Therefore,it is necessary to implement high-quality development,form a water-saving lifestyle,improve water use efficiency,develop and imple⁃ment life water-saving policies around family development,enhance the awareness of water saving,and establish an advanced quota system for domestic water.
