本研究的目的在於探討台灣家庭用戶夏天用電需求的決定因素,並探討夏天用電與冬天用電需求的差異因素。本研究係採用台電公司於92-94 年度的「台灣地區家用電器普及狀況調查研究報告」的原始調查資料,透過建構(1)夏天家戶用電需求,與(2)夏天與冬天家戶用電需求差異兩種迴歸模型,並採用線型與半對數兩種需求模式,進行一般最小平方法迴歸估計。The purpose of this study is to investigate the factors that affect the electricity demand of households during the summer time and the differences on electricity demand between summer and winter in Taiwan. Our study uses the individual household survey data obtained from the “2003 Taiwan Household’s Appliance Usage Survey” by Taiwan Power Company. We construct two electricity demand models that include the summer demand and the differences between summer and winter demand. The demand models are employed the linear and semi-log forms and used the ordinary least square estimation.
