长江经济带典型城市居民生活用水价格承受能力分析

Analysis on the Affordability of Domestic Water Prices for Residents in Typical Cities in the Yangtze River Economic Belt

本文梳理了水价承受能力研究方法和国内外大中城市水价水平,使用变系数双对数模型分析长江经济带典型城市上海、武汉、重庆、芜湖、九江2012—2022年居民生活用水经济承受能力和心理承受能力。结果显示,从经济承受能力来看,长江经济带典型城市居民生活水费总体水平较低,居民用水价格弹性和收入弹性较小,有一定的调价空间,但水质满意度较低、生活压力上升、缺乏沟通等因素影响了居民对水价的心理承受能力。建议适时适度逐步提升价格水平,政府和居民合理分摊水务系统各环节费用,通过市场开放和竞争,提供质优价廉的服务、完善社会救助体系,减轻低收入群体负担。

This paper reviews the research methods of water price affordability and the water price level of large and medium-sized cities in China and abroad,and uses the variable coefficient double logarithmic model to analyze the economic and psychological affordability of residents'domestic water supply in Shanghai,Wuhan,Chongqing,Wuhu and Jiujiang in the Yangtze River Economic Belt from 2012 to 2022.The results show that the overall level of domestic water charges of residents in typical cities in the Yangtze River Economic Belt is low,and the elasticity of water price and income of residents is low,and there is some room for price adjustment,but shall consider psychological factors such as low water quality satisfaction,rising living pressure,and lack of communication.It is recommended to gradually raise the price level in a timely and appropriate manner,improve the cost distribution,provide high-quality and low-cost services through market opening and competition,and improve the social assistance system to reduce the burden on low-income groups.
