隨著環保意識的抬頭及歐盟法令WEEE之規範，加上現今生產技術的進步，使得耐久財產品的生命週期越來越長，二手市場的發展也愈發篷勃，世界各國紛紛開始注重產品回收與再生之問題。 本研究主要探討對象為高涉入二手產品，嘗試達成下列研究目的：一、探討消費者對高涉入二手商品購買的態度與消費者心理因素之影響。二、探討環保意識對消費者購買高涉入二手商品是否有相關性。三、探討高涉入二手市場中，品牌與購買意願間之相關性。四、探討高涉入二手市場中，知覺風險與購買意願間之相關性。 針對306份有效問卷進行分析，實驗包含的自變數有五項，分別為儉約、環保意識、消費者企業社會責任認同度、產品的品牌評價、產品的知覺品質、產品的知覺風險，進行其主要效果和應變數-消費者購買意願間之關係。研究結果除了環保意識之外，其餘變數皆與消費者意願有顯著相關。 With the rise of environmental awareness, the applications of EU WEEE regulations, and the advancement of technology, the life cycles of durable commodities is lengthened.
