Analysis of households' electricity, gas and gasoline demand using micro data from the National Survey of Family Income and Expenditure

摘要

For building a sustainable city, it is essential to understand the energy use behaviour of households. In this paper, I analyse the relationship between a household's electricity, gas, and gasoline consumption, using data from the National Survey of Family Income and Expenditure of Japan. Then considering household characteristics, price, income and population density, elasticities of these energy demands are estimated using regression analysis. As a result, the following three major conclusions are obtained: (1) correlation among households' electricity, gas, and gasoline consumption are low, (2) price and income elasticities are differentiated by an equivalent income level, and (3) with regards to population density, elasticity of gasoline is negative but those of electricity and gas are positive.
