代言人類型之廣告效果研究
A Study on the Advertisement Effectiveness of Endorser type
摘要
「美麗吸引力」、「專業形象」是廣告主選擇代言人時重要的特質，過去的研究偏重在哪一類型代言人有較佳的廣告效果，較無探討當結合不同產品類型時，如何制定代言人選擇策略；許多名人如偶像歌手等，經常在同一時間代言許多產品，當其代言的產品之間具有關聯性時，對廣告效果是否有影響也是過去研究較少著墨之處。本研究以「美麗吸引力」及「專業形象」為代言人選擇策略的因素，在研究一中結合符合FCB Grid四個象限的產品，為2X4的實驗設計，量測廣告態度、廣告說服力及購買意願，並進一步了解研究對象的性別與代言人是否有交互作用；研究二則是2X3的實驗設計，以相同的代言人推薦互補品、替代品及產品效果抵消的產品組合，同時將研究對象分成高低認知需求二群組，探討其對廣告態度、廣告說服力及購買意願的影響。 研究對象為對一般上班族進行問卷調查，有效問卷315份，其結果如下： 一、「美麗吸引力」類型的代言人，對FCB Grid四個象限的產品均有較佳的廣告態度，而代言人類型與產品類型無顯著交互作用 二、代言人類型與研究對象性別有交互作用，「美麗吸引力」代言人對男性有較高的廣告態度 三、代言人類型與產品關聯有交互作用，「美麗吸引力」代言人在互補品及替代品有較高的廣告態度，而「專業形象」代言人對產品效果抵消的廣告態度無顯著影響 四、認知需求的高低，與代言人類型沒有交互作用 五、研究結果顯示，在大部份的情境下不論何種類型的代言人，對廣告說服力及購買意願較無顯著影響

The purposes of this research were to examine the effectiveness of physical attractiveness and expertise for different product types and product correlations. We presented two studies which were very similar in design and method. Study One was a 2 X 4 experiment in which investigated the effectiveness physical attractiveness and expertise, paring with different types of product which were categorized into 4 quadrants based on FCB model, on the advertisement attitude, advertisement credibility and purchase intention. In addition, we further investigated the interaction of endorser type by subject’s gender. Study Two was a 2 X 3 experiment which manipulates the same endorsers in study one, physical attractiveness and expertise, for three different product correlations, complement, substitute and counteract and examined the effectiveness on advertisement. One personal variable, need for cognition(NFC), was added in study two in which examined the effects of NFC on consumer behavior by categorizing the subjects into two groups, high and low NFC. The subjects were salary men and the results are summarized as following: 1.The physically attractive endorser was more favorable on advertisement attitude for four types of product in FCB Grid. On the other hand, there was no significant interaction effect on endorser type by product. 2.Study One showed significant endorser type by subject’s gender interaction on advertisement attitude. Particularly, the attractive female endorser generated more enhanced attitudes among males. 3.In Study Two, it presented a significant endorser type by product correlation interaction on advertisement attitude. The complement and substitute product were favorable when endorsed by attractive spokesperson versus expert spokesperson. However, expert endorser had no significant effect on advertisement attitude for counteract product correlation. 4.No endorser type by NFC interaction in Study Two. 5.In most conditions, the observed advertisement credibility and purchase intention were not significant for both endorser types, physically attractive and expertise.
