我國於西元2002年正式成為WTO會員國,國外廠商進入本國市場障礙也逐漸降低。在市場開放下,消費者在購買農產品時,是否因來源國形象(country image)影響其購買行為?本文主要研究消費者是否因為產品的來源國形象而有暈輪效果(halo effect),並在單一指標與多重指標衡量來源國形象下,檢測實證結果是否有差異。驗證結果發現單一指標衡量來源國形象時,台灣蘋果與美國蘋果會存在暈輪效果;若以多重指標衡量來源國形象時,則日本蘋果與美國蘋果存在暈輪效果。顯示兩種不同來源國形象衡量方式在暈輪效果上的檢測會有差異,且建立良好的國家形象將影響消費者購買該國的農產品。
Since Taiwan became a member of the WTO in 2002, the baffler for entering Taiwan's market for foreign manufacturers has been lowered. Under entry conditions, will a country's image affect what agricultural products consumers purchase? This paper looks at whether or not the country's image would produce a Halo Effect on consumers and measures the differences using uni-dimensional and multi-dimensional methods. Our research shows that a Halo Effect occurs in consumers of Taiwan and American apples when both countries' images are evaluated in an uni-dimensional way. Moreover, the Halo Effect occurred in consumers of Japanese and American apples, when both countries' images were evaluated in a multi-dimensional way. So the foundation of a favorable country image has influence on consumers' buying of agricultural products.
