城市污水处理收费标准的提高对居民承受能力的影响

The Effect of the Increase of Urban Wastewater Treatment Fees on Residents' Affordability

以四川省14个市县污水处理设施的融资战略分析材料为基础,首先对现行收费标准下家庭用于水和污水处理方面的支出进行了分析,并对承受能力之内的居民支付意愿进行了调查统计;利用FEASIBLE模型模拟了3种未来可能增加融资的战略,并进行了说明;在分析了不同融资战略下收费标准的增长速度后,对3种战略下城市污水处理设施收费标准的提高对居民承受力的影响进行了研究。结果表明,如果没有保护贫穷和弱势家庭的相应措施,那么任何大幅的收费增长都将难以实现。

Based on analysis of environmental financing strategies for the urban wastewater sector in the selected municipalities/counties of Sichuan province in China, the expenditure on water and wastewater in families was analyzed and the willingness to pay （WTP） for water supply and wastewater treatment investigated. Three possible financing strategies for the future were simulated by FEASIBLE model and explained one by one.After analysis of the increase of the expenditure under different financing strategies, the affordability concerning the rise of wastewater treatment fee in different scenarios was analyzed. The result shows that if there are no related measures to protect poor families, any big increase in the expenditure can not be reached.
