摘　　要：基于2009—2018年长江经济带11个省市水足迹的面板数据,运用Tapio脱钩弹性系数模型研究水足迹与经济高质量发展之间的脱钩效应,利用STIRPAT模型研究水足迹强度的驱动因素。研究结果表明:长江经济带水足迹总量在2016年出现拐点后逐年下降,而经济高质量发展水平整体处于稳步上升状态,二者整体上呈现弱脱钩趋势。其中,长江下游省市基本实现强脱钩,中上游省市从弱相关性向强相关转变。Based on the panel data of water footprint in 11 provinces and cities in the Yangtze River Economic Belt from 2009 to 2018,the Tapio decoupling elastic coefficient model is used to study the decoupling effects between the water footprint and the high-quality economic development,and the STIRPAT model is further used to study the driving factors of water footprint intensity.The conclusions show that the total amount of water footprint in the Yangtze River Economic Belt decreases year by year after the inflection point in 2016,while the overall level of high-quality economic development steadily increases,and they exhibit a weak decoupling trend.Among them,the provinces and cities in the lower reaches of the Yangtze River have basically realized strong decoupling,and those in the middle and upper reaches change from weak correlation to strong one.
