| 摘 要： | 以重庆市为例,对居民生活用水现状及城市供水的定价进行分析研究,基于ELES模型,分析重庆市居民生活用水水价的支付能力。结果表明:水费支出承受能力随可支配收入的增加而增加;用水需求收入弹性随可支配收入的增加而增大;低收入户的生活用水基本需求支出处于警戒线;2016年重庆市实施了阶梯水价的计价方式,定价基本合理,存在一定的改进空间。

| Abstract: | Taking Chongqing City as an example, the current situation of domestic water consumption and the pricing of water resources are studied. The ability to pay the price of domestic water in Chongqing is analyzed by using the ELES model. The results show that the burden of water expenditure decreases with the increase in the urban households'' disposable incomes. At the same time, the income elasticity of water demands for urban households will improve with the increase in disposable incomes. For the low-incomes urban households, the fundamental domestic water demands cannot be fulfilled. In 2016, the multistep water price was implemented in Chongqing City. The pricing of urban domestic water is basically rational, however, it has some space to be improved. |
