隨著科技的進步,人們的在追求生活品質與健康的同時,也開始意識到環境保護的議題,使得天然無毒的有機食品因而受到關注。而國內有機商品專賣店迅速擴張,例如:聖德科斯、里仁、無毒之家和棉花田等,顯示有機食品商機無限。據此,本研究以Ajzen(1975)所提出的計劃行為理論為基礎,探討消費者對有機食品的態度、主觀規範和知覺行為控制與購買意圖之間的關係,並加入知覺價值和產品知識等變數加以衡量,針對台灣消費者有機食品購買行為進行探討。 本研究對象進行人員紙本發放和網路問卷等方式施測,並使用SPSS18.0版和LISREL8.7版作為資料分析工具。經由結構方程模式驗證研究假說可得知以下結論: 一、台灣消費者對有機食品的態度、主觀規範和知覺行為控制確實會影響消 費者對有機食品購買意圖的形成。 二、台灣有機食品市場中,消費者的知覺價值能直接影響有機食品之購買意 圖,且態度具有部份中介效果。 三、台灣有機食品市場中,消費者所擁有的產品知識對於購買意圖的影響,態度 並未扮演中介角色,而知覺行為控制則扮演重要的完全中介角色。 根據本研究之資料分析結果,發現台灣有機食品市場中,消費者的主觀規範為影響有機食品購買意圖最重要的影響力,其次為知覺價值和產品知識,並提供廠商未來制定決策的參考和後續研究的研究限制。
As the advancement of technology, people start to purchase the quality of life and health, in the same time, the issue of environmental protection is also become popular.
