我们的目的是实证研究消费者对公用事业产品的必要和额外需求。我们的论文有三个贡献。首先,利用随机前沿模型,我们确定了消费者的消费中的必要需求和额外需求。其次,我们计算消费者消费中的必要需求和额外需求的比率,并比较两者的相对重要性。第三,我们考察了内部和外部激励对额外需求的影响。通过对2012年557户日本家庭的用电量数据进行实证调查,得出以下结果。首先,房屋面积、电器数量、家庭规模等物质条件决定了必要需求。第二,单靠需求响应机制并不能减少额外需求,而与节能意识相结合则可以减少额外需求。第三,由于必要需求构成了总消费的主要部分,因此,对优化消费者物质条件的研究很重要。
Our purpose is to empirically investigate necessary and extra demand of a consumer for public utility product. Our paper makes three contributions. First, using the stochastic frontier model, we identify necessary and extra demand in a consumer’s consumption. Second, we calculate the rates of necessary and extra demand in a consumer’s consumption and compare the relative importance of the two. Third, we examine the effects of internal and external incentives for extra demand. By empirical investigation using electricity consumption data on 557 Japanese households in 2012, we obtain the following results. First, physical conditions such as house size, the number of electric appliances, and family size surely determine necessary demand. Second, the demand response mechanism alone does not reduce extra demand, while it can reduce extra demand when combined with the consciousness of saving energy. Third, since necessary demand comprises the preponderance of total consumption, investigations into optimizing the physical conditions of consumers are important.
