台灣每年售出的手機約為七百萬支，但廢棄手機回收率卻未達三成，廢棄手機之數量不容小覷。廢棄手機回收的主要原因為手機有90%的部分可以再次利用，並擁有相當高的回收價值，且可避免有毒物質造成環境汙染。 本研究參考國內外相關理論文獻，整理各國手機回收系統運作現狀，得出知識、態度、便利性、法規與經濟性等五大構面及十九項評估要素及資源回收、閒置家中與直接丟棄三個手機處理方案，透過階層分析法建立廢棄手機回收決策架構，找出影響民眾在廢棄手機回收處理方式選擇之重要影響因素。 研究結果顯示，民眾在決定如何處理廢棄手機時，便利性與經濟誘因是最大的兩個關鍵構面。進一步探討，處理流程便利性以及回收獎勵金是最關鍵的影響因素。敏感度分析得知，態度構面下的家庭習慣讓受訪者傾向選擇閒置家中，顯見目前家庭之手機廢棄方式普遍為閒置家中。 因此除了增加回收的便利性及提供實質獎勵金與獎勵品等正面經濟誘因外，由於現階段家庭習慣對於將廢棄手機閒置家中，更應從家庭教育著手來加強對於回收的正面態度。The selling volume of new mobile phone in Taiwan is close to seven million per year. Huge amount of waste mobile phones are generated every year. The recycling rate of waste mobile phone is less than 30%, which is too low. Recycling mobile phone is valuable, and can bring high recycling value. At the same time, recycling can prevent the environment from being polluted. The related literature and the applications from several countries we collected and organized help to generate five dimensions, nineteen factors, and three alternatives. By using Analytic Hierarchy Process (AHP), it built up an evaluation model and the decision making structure to find out the key factors that influence people in dealing with their waste mobile phones. Results indicate that the convenience and the economic inducement are the top two key dimensions; the convenience of dealing process and monetary incentives are the top two key factors for people. According to the sensitivity analysis, the family habits cause people leave the waste mobile phone at home instead of recycling. Therefore, in addition to increase recycling convenience and to provide substantial positive economic incentives, the positive attitude towards recycling through family education should be strengthen.
