 本研究利用聯合分析法,探究我國消費者對基改食品的偏好與福利變化,分析係針對木瓜、稻米、大豆與玉米等作物與其加工產品進行。研究結果發現,消費者對 食品經基因工程改造有負效用值,但對人體健康或環境有幫助的產品特性,如外觀改善、營養價值增加、殺蟲劑與除草劑施用量減少,會帶給消費者正效用值。對環 境有益之生產技術如有機或準有機種植,也會帶給消費者正效用值。消費者的教育程度越高越排斥基改技術,但對改善食品之特性有較高的效用值。消費者對於基改 技術之願付價格均為負值,以稻米最低為-32.97元,對於種植過程減量施用殺蟲劑與除草劑的願付價格為-6.82~-90.19元。產品屬性所產生的正 效用值中,對稻米的胡蘿蔔素願付價格最高為85.34元,對木瓜外觀的改善為8.64元;對有機與準有機種植技術為11.82~70.3元,其中對有機的 願付價格均高於準有機。研究結果顯示,平均而言我國消費者會傾向購買非基改、外觀良好、營養價值高與減少農藥施用量的產品。

This study investigates preferences and welfare changes of Taiwan’s consumer on genetically modified (GM) foods. Conjoint analysis is used to elicit consumers’ preferences for attributes on papaya, rice, soybean, and corn. Results indicate that consumers in Taiwan place positive utility on improving product appearance and nutrition and on lowering ag-chemicals applications, while revealing negative utility on GM technology for food. Positive utility is also found on organic and quasi-organic foods. Willingness to pay (WTP) for GM technology is negative for all products, with the lowest on rice of NT$-32.97s. Negative WTP is also found in ag-chemicals (NT$-6.82 to -90.19). Positive WTP on attributes include NT$85.34 for carotene of rice, NT$8.64 for improving appearance of papaya, and NT$11.82~70.3 for organic/ quasi-organic products. In general, consumers in Taiwan would choose a food product with characteristics of non-GM, better appearance, nutrition fortification, and lower ag-chemicals applications.
