如果家用电器的使用模式因家庭而异，那么我们预计家用电器的更换周期也会因家庭而异。尽管许多研究确定了新的节能产品的早期采用者，但很少有研究调查一直在使用旧的低能效产品的家庭，以及它们的特征与产品更换的关系。在本研究中，我们初步修正了一个生存函数，并建立了一个经济模型来评估家庭特征对家电更换的影响。随后，我们将该模型应用于从日本环境部获得的家庭二氧化碳排放调查的微观数据分析中。我们使用冰箱(参考文献)的年龄分布信息，并研究家庭规模、家庭收入和户主年龄如何影响参考文献的更换周期。我们的实证结果显示，(1)大型家庭、(2)高收入家庭和(3)年轻家庭更换参考文献的速度更快。这些发现表明，需要鼓励小规模、老年和低收入家庭更换旧家电的政策。
If the pattern of appliance use varies between households, then we expect that appliance replacement cycle also varies between households. Although many studies identified early adopters of new energy-efficient products, few studies have examined households that have been using old energy-inefficient products and how their characteristics are associated with product replacement. In this study, we initially modify a survival function and develop an economic model to evaluate the impact of household characteristics on appliance replacement. We subsequently apply the model in microlevel data analysis from the Survey on Carbon Dioxide Emission from Households obtained from the Ministry of the Environment of Japan. We use information about age distribution of refrigerators (REFs) and examine how family size, household income, and age of household’s head affect the replacement cycle of REFs. Our empirical results reveal that (1) large-sized, (2) high-income, and (3) young households replace REFs more rapidly. These findings suggest that policies that encourage small-sized, elderly, and low-income households to replace old appliances are needed.
