Abstract: This paper analyze nonlinear pricing on income redistribution effect by the introduction of household characteristics under time-of-use pricing cum increasing block pricing. By constructing Quadratic Almost Ideal Demand System (QUAIDS) that is introducing household demographics, we established the adjusted income redistribution effect measurement model based on utility maximization theory and relative equivalent compensation method. Then we estimate the rates of electricity compensation and its amounts which are needed to increase in order to keep the same utility when the household size changed. The results show that, firstly, the income redistribution effect is reinforced in considering household characteristics. Secondly, family characteristics have important influences on consumer choice. Thirdly, dynamic analysis shows that, with the improvement of the budget level, the influences of household demographics on income redistribution effects is decreasing.
