貧窮一直是許多國家普遍存在的問題,對台灣來說也是如此,本研究論說台灣低收入戶的形貌及特性,探討失業率與經濟成長率對貧窮及脫貧造成的影響,並放入吉尼係數比較參考,研究資料為台灣健保資料庫中的承保資料檔,因為承保資料檔明確地劃分各類目之被保險人,對於投保人員身分的流動有詳細記載,可檢視個人貧窮歷程的演變,經適當的處理後,再歸納出依據假說所需要的變數,利用統計軟體STATA進行迴歸分析,研究期間為1996年到2007年,樣本以1996年成為低收入戶的個人為固定樣本,並針對此樣本作長期追蹤,並以最小平方法(OLS)、障礙模型(Hurdle model)估計各變數對低收入戶的貧窮年資、脫貧機率、脫貧年資的影響。希望能在社會福利制度與貧窮門檻制定上提供有利的貢獻,找出影響貧窮趨勢的重要因素。
