实行居民生活阶梯电价是节约能源、保护环境及建立公平负担电价机制的重要途径，家庭收入、日常消费支出与用电量的关联关系是制定居民生活阶梯电价方案的重要依据。首先，针对居民的家庭月平均收入、家庭月平均消费支出及家庭月平均电费支出对天津市居民进行了抽样问卷调查并分2步对调查数据进行预处理；其次，运用绘制散点图的方法初步确定了家庭月平均收入、家庭月平均消费支出与家庭月平均用电量的正相关关系，并在此基础上分别建立了家庭月平均收入、家庭月平均消费支出与家庭月平均用电量的回归方程；最后，对所建立方程的有效性进行了统计检验。分析结果可为居民生活阶梯电价电量的分档以及各档电价水平的确定提供理论支持。

Residential Step Electricity Pricing is an important approach to energy conservation, environmental protection and construction of a fair-sharing electricity pricing mechanism, and the correlations between household income, daily consumption expenditure and power consumption is an important base for establishment of Residential Step Electricity Pricing. Firstly, this paper makes a sampling questionnaire survey of Tianjin residents in terms of average monthly household income, daily consumption expenditure and electricity consumption and makes a two-step pretreatment; secondly, a positive correlations between average monthly household income, daily consumption expenditure and electricity consumption is established initially by drawing scatter diagrams, on the basis of which two curve regression equations involving average monthly household income, daily consumption expenditure and electricity consumption are established; finally, the validity of the two equations is tested by statistics. The results of the study in the paper can provide a theoretical support for partition of the power consumption and determination of the corresponding pricing levels for Residential Step Electricity Pricing.
