摘要：现在，决策者制定家庭用水价格时，往往需要需求侧信息，而不像从前那样只参考供给侧信息，而家庭调查通常是用于收集需求侧信息。为收集不同类型家庭对不同水价的可接受程度的信息并估计家庭对用水服务改善的支付意愿，本文提出了多重有限离散选择（MBDC）调查模型。从MBDC调查取得的成果可直接用于用水定价与补贴政策调整。对中国重庆五个市区1500户家庭的MBDC经验调查显示，虽然当地供水部门对家庭用水服务质量极为恶劣，且地方财政不足以改善服务质量，但只要对最贫穷的家庭给予适当补贴，那么大幅提高水价在经济上就是可行的。分析还显示，利用MBDC方法提出的分级假定价格能系统性影响被调查者的回答，而在设计调查方式时应该对此进行考虑。

Abstract: In determining domestic water prices, policy makers frequently need to use demand-side information rather than only rely on supply-side data as previously did, and household surveys are often conducted to collect information on the demand side. This paper presents a multiple bounded discrete choice (MBDC) survey model for collecting information about acceptability of different water prices by different types of households and estimating households' willingness to pay for water service improvement. The results obtained from MBDC surveys can be directly utilized in the development of water pricing and subsidy policies. An empirical MBDC study is conducted in Chongqing, China, where domestic water service quality was seriously inadequate, but financial resources were insufficient to improve the service quality. With a survey of 1500 households in five suburban districts in Chongqing Municipality, this study shows that a significant increase in water price is economically feasible as long as the poorest households are properly subsidized. The analysis also indicates that the order in which hypothetical prices are presented to the respondents with the MBDC method can systematically affect the answers and should be taken into account when designing such survey instruments.
