本篇論文旨在探討影響台灣汽油需求之因素,特別針對兩段油價趨勢相當期間的價格彈性和所得彈性做分析,且分別從總體和個體的角度研究影響汽油需求之因素,最後再比較兩者之異同。 本研究第一部分利用總體資料討論影響各縣市汽油需求之因素,蒐集2003年5月至2008年5月(共61個月)和2009年6月至2011年12月(共31個月)台灣本島各縣市汽油月消費量等資料,利用上述兩段時間的縱橫資料建立固定效果模型。第二部分利用個體資料討論影響家計部門汽油需求之因素,資料來源為交通部統計處「台灣地區自用小客車使用狀況調查」問卷資料,利用2002年、2004年、2006年、2008年、2010年的問卷資料,以加權最小平方法(WLS)分析。 實證結果發現臺灣的汽油需求價格彈性維持在約-0.35,此外在2008年油價先上升而後下降的趨勢之下,汽油需求價格彈性是變小的,約-0.27,2010年油價維持在較高時,汽油需求價格彈性是變大的,約-0.53,長期來看,近年來的汽油需求價格彈性較大。而臺灣的汽油需求所得彈性則維持在0.09~0.14之間。 This essay is aimed to discuss the reasons that influence gasoline demand in Taiwan, by analyzing the Price Elasticity and the Income Elasticity of Demand within two certain periods of time, from the Statistical Population and the Individual Economy aspects. The first part of this essay will approach from the Statistical Population data, stating the reasons which influence monthly gasoline consumption within Taiwan by the statistics collected from May 2003 to May 2008 (61 months in total) and from June 2009 to December 2011 (31 months in total). It also generates a Fixed Effect Model by using the Panel Data within the mentioned periods. Meanwhile, the second part will approach from the Individual Economy viewpoint to portrait the causes of different household gasoline requirements, by using WLS to exam the Research of Private Automobile Usage in Taiwan, polling by Ministry of Transportation and Communications, Department of Statistics in 2002, 2004, 2006, 2008 and 2010. Although while the average Price Elasticity of gasoline demand is about -0.35, the Price Elasticity declines (-0.27) due to the increased and then decreased pricing occurred in 2008 and an increased Price Elasticity (-0.53) is also found when higher gasoline price shown in 2010. And the Income Elasticity of gasoline demand in Taiwan is about 0.09 to 0.14 in recent years.
