摘　　要：为实现水资源约束下的水资源可持续发展,运用超效率EBM模型测算了2012—2021年长江经济带11个省市工业用水效率,通过空间杜宾模型探究了异质性环境规制对长江经济带工业用水效率的影响。结果表明:长江经济带各省市的工业用水效率有明显差异化,上、中、下游的工业用水效率呈现两端高、中间低的趋势;命令约束型、市场激励型和公众自愿型环境规制促进了工业用水效率的提高;异质性环境规制对工业用水效率具有较强的空间溢出效应,命令约束型和市场激励型环境规制具有污染转移效应,不利于邻近地区工业用水效率的提高。In order to solve the problem of realizing sustainable development of water resources under water resource constraints,the article takes 11 provinces and cities in the Yangtze River Economic Belt from 2012 to 2021 as research objects,measures the industrial water use efficiency of the 11 provinces and cities by using the super-efficient EBM model,and further explores the impact of heterogeneous environmental regulations on the industrial water use efficiency of the Yangtze River Economic Belt by using the spatial Durbin model.The results show that industrial water use efficiency of the provinces and cities in the Yangtze River Economic Belt is significantly different,with the industrial water use efficiency in the upper,middle and down reaches showing a trend of high upstream and downstream and low in the middle reach.Command-constrained,market-incentivized and public-voluntary environmental regulations promote the improvement of industrial water use efficiency.Heterogeneous environmental regulations have a strong spatial spillover effect on industrial water use efficiency.Command-constrained and market-inspired environmental regulations have a pollution transfer effect on neighboring cities,which is not conducive to the improvement of industrial water use efficiency in neighboring cities.
