食品安全衛生事件在台灣時有所聞,消費對產品的資訊不足,往往導致逆選 擇,對產業及消費者造成負面的影響,政府為了保障消費者的飲食安全,並與國 際接軌,於2004年起推動農產品推動產銷履歷制度(Traceability system)。農產品 推動產銷履歷制度是目前世界農業生產與消費的趨勢,「產銷履歷記錄」即從生產到 銷貨至消費者手中有可追蹤的記錄。 本研究選擇生產履歷茶為受測產品,主要目的為分析生產履歷茶如何透過知 覺保證及知覺價格來影響知覺品質,並且探討生產履歷茶如何透過知覺品質和知 覺犧牲的連結來影響知覺價值和購買意願,以獲得顯著性影響構面因素,提供相 關單位及經營者訂定相關改善的策略。以 Monroe and Krishnan(1985)的知覺評估 流程為基礎,並納入生產歷歷茶的特色「知覺保證」此變數,分析消費者對生產履歷 茶的「知覺價值」,做為生產履歷茶購買意願的評估。 研究發現生產履歷茶的兩項特徵「知覺價格」和「知覺保證」均具有傳達品質訊 號的功能,「知覺品質」又正向影響「知覺價值」和「購買意願」,但價格除了正向影 響知覺品質外,也正向影響知覺犧牲。本研究的結果再度證實Monroe and Krishnan (1985)和Zeithaml(1988)的論點,「知覺價值」為影響「購買意願」最重要 的因素,且「知覺價值」是「知覺品質」和「知覺犧牲」二者的權衡。
Traceability systems are recordkeeping systems that keep product information from the creation through marketing. Such systems are important in ensuring food safety and consumer welfare, particularly when information asymmetric exists. Consequently, the government has introduced the voluntarily traceability system for agricultural products in 2004. Using tea with traceability system as an example, the purpose of this study is to examine if traceability is an effective cue in impacting consumer’s perceived quality via perceived warranty and perceived price. In addition, this study also investigated whether perceived warranty induced by traceability system enhances perceived value and thus consumer’s purchase intention, based on Monroe and Krishnan (1985). The study found that both perceived price and perceived warranty are effective cues for perceived quality which in turn positively enhances perceived value and purchase intention. Furthermore, this study also found that product price has a positive effect on both perceived quality and perceived sacrifice. All of these findings further confirmed Krishnan’s (1985) and Zeithaml’s (1988) proposition that perceived value is the most important factor influencing consumer’s purchase intention and that perceived value is a result of moderating effect between perceived quality and perceived sacrifice.
