居民水价递增阶梯结构与政策效应研究

The Structure of Residential Increasing Block Water Tariffs and Policy Effects

以两级阶梯的递增阶梯价格结构为例,探讨水量和水价等结构变量与政策效应之间的关系,以及居民阶梯水价政策的实施对居民水费支出的影响。研究发现,阶梯水量与阶梯水价共同对政策效应产生影响,居民水费支出的变动幅度取决于消费者的需求强度,这对于居民阶梯水价政策的进一步完善有一定的意义。

This article takes the price structure of two-levels as a case study to analyze the relationship between the threshold or price of the tariff and IBTs＇policy effects,in which residents＇expenditure on water is also discussed .It shows that both the threshold and price affect the policy effects,and the volatility of residents＇expenditure on water depends on the demand intensity of consumers.
