台灣2009年民間消費占GDP約60.8%,過去十年來,民間消費占GDP比率皆約有50~60%,消費的增長對於經濟增長的貢獻率最大,成為拉動內需及促進經濟發展的動力,本研究所探討民間消費支出與實質所得、實質利率與加權股價指數四項因素之關係。研究樣本期間為2000年第一季至2009年第四季之資料,共計40筆樣本資料。本研究得到下述研究結論: 1.台灣地區之消費支出顯著地受股價、所得與利率之影響。 2.探討所得、股價與利率對消費的因果關係影響: (1)民間消費對實質所得大於加權股價指數與實質利率的因果關係。 (2)實質所得對實質利率有單向因果關係。 (3)實質利率則對於民間消費、實質所得與加權股價指數則無任何因果關係。 (4)可藉由加權股價指數觀察對民間消費和實質所得之變化。 3.將消費支出細分為12項,實質所得如何影響消費支出。 (1)被分類為奢侈財的有:家具設備家務維護、醫療保健、通訊和休閒與文化,共四項消費支出。 (2)被分類為必需品的有:食品及非酒精飲料、住宅水電瓦斯燃料、交通、娛樂消遣教育和餐廳及旅館,共5項消費支出。
