| dc.description.abstract | 由於基因改造食品的低成本、高產出性使得其技術已廣泛的應用於農作物上。因為大量商業化的應用也造成消費者對於基因改造食品的安全性有存在一定的顧慮。本研究使用2008年問卷資料來探討時下消費者對於購買基因改造食品的意願和其願付價格。從問卷資料中挑選出人口(消費者)特性、消費者對於基因改造食品的知識、觀感以及態度等變數套入多項羅吉模型來探討消費者對於購買基因改造食品的意願。消費者的願付價格可透過存活分析的方法來進行估算。研究發現台灣受訪者對非基因改造大豆沙拉油之平均願付價值為$325，為GM價格的2.03倍。此結果表示台灣地區的消費者對於基因改造食品的認識還是相當有限的。因此有關單位應加強基因改造食品的宣導教育和品質控管、來滿足消費者對於健康安全的需求。 | zh_TW |
| dc.description.abstract | Low production costs accompanying by high production yields make the technology of genetic modified (GM) organism widely applied in agriculture business sectors. These massive commercial usages of GM products concern consumers regarding the food safety. This research analyzes the consumer’s acceptance and willingness to pay (WTP) values based on the data gathered from survey conducted in year 2008. Variables from demographics, GM knowledge and consumer’s attitude and perception are extracted and conjointly determining the acceptance of GM foods with multinomial logit model. Moreover the consumer’s WTP value can be estimated by the survival analysis techniques. The empirical finding elicits an average WTP amount of $325 for non-GM vegetable oil. Taiwanese consumers on average are willing to pay 2.03 times the price of GM vegetable oil for a 3-Liter non-GM vegetable oil. This fact infers that consumers in Taiwan still have limited knowledge in interacting with GM foods. Thus, policy makers should enforce the education and regulation imposed on the GM technologies in order to satisfy the consumer’s demand of pursuing health and food safety. | en |
