在分析影响居民电力需求的因素的基础上 ,从微观角度研究居民家庭的电力消费行为的数量表现。根据扩展线性支出系统理论建立电力消费的需求函数 ,并对居民电力消费需求的收入弹性、价格弹性进行定量分析。结果表明 ,扩展线性支出系统既可用于电力消费的分析 ,也可用于电力需求的预测。
Based on the analysis of the factors affecting residents’ electricity demand, this paper studies the quantitative performance of household electricity consumption behaviors from a micro perspective. According to the theory of extended linear expenditure system, the demand function of electricity consumption is established, and the income elasticity and price elasticity of residents’ electricity consumption demand are quantitatively analyzed. The results show that the extended linear expenditure system can be used for both the analysis of electricity consumption and the forecast of electricity demand.
