本研究從長時間來觀察台灣香菸稅捐的累退程度變化，並且同時觀察台灣吸菸家庭具備何種特徵，以作為政府相關單位在制定租稅及菸害防制等政策的一個參考。利用行政主計處之「家庭收支調查報告」、台灣省菸酒公賣局之「臺灣地區菸酒事業統計年報」及學者研究等資料來進行累退性衡量，發現自1979年開始至2007年，我國香菸稅累退程度呈現加劇的情形，而各吸菸家庭則呈現出菸草消費支出金額愈高者戶長及家庭成員平均年齡愈低、教育程度較低、以及女性戶長比例下降等特徵。 由此結果可看出我國香菸稅累退程度並未減輕，低所得家庭反而較高所得家庭負擔為重，此外菸草消費支出較高的家庭由於平均教育程度較低，普遍缺乏吸菸會造成健康危害的風險認知，因此衛生醫療主管當局應加強菸害防制教育以利提升國民健康。 / This study observes the regressivity changes of cigarette taxation in Taiwan for long run and the features of smoking families in Taiwan to offer the government and relevant organization a reference in making taxation and tobacco hazards prevention policies.
