本研究目的在探討代言人的選用策略、代言人代言數量、產品涉入程度與廣告效果之間的意涵；分析人口統計變數對廣告效果的差異性；檢定產品涉入程度、代言人代言數量多寡之間對廣告效果的關係。根據量化分析及質化訪談的研究分析，對代言人的選用策略提出整合研究建議。 研究方法採取量化的實驗法及質化的深度訪談進行，以實驗法進行的過程，先針對代言人代言數量多寡進行人選的前測，再與涉入程度高低不同程度的商品搭配，設計出一組3*2的實驗組合。透過統計檢定導出結論，再輔以實際廣告業界當中，從廣告主及廣告代理商的深度訪談佐證，最終再提出名人代言的選用策略建議。 根據實驗的結果統計歸納，摘要四點結論如下： 一、名人多品牌大量代言等於高知名度，廣告效果仍佳。 二、代言人代言數量過多導致推荐疲乏雖然存在，但對廣告效果影響有限。 三、在商品涉入程度的關係中，名人代言策略建議用在低涉入產品中，高涉入產品效果較差。 四、代言人的選擇應考慮目標對象的性別及教育程度進行遴選標準。 根據廣告主及廣告公司等業者的訪談，提出八項建議如下： 一、依據代言人性格及品牌關聯，為名人量身打造廣告，破解可能的推薦疲乏。二、經由代言人成為「品牌大使」的角色，發揮品牌精神。 三、為避免折損名人價值，名人應嚴選合作品牌，與品牌適配結合。 四、創造虛擬偶像或素人明星為操作代言人的奇兵策略。 五、整合性名人代言的傳播決策路徑 六、避免喧賓奪主效應，發展名人與品牌之間的雙贏及共生關係。 七、用名人自己平常慣用的語言及消費者認同的語言來溝通。 八、理性與感性建立品牌人格化模式。 / The purpose of this study is to explore the strategy of choosing advertising spokesperson, the number of endorsements, the meaning between product involvement and advertising effectiveness.

近年來，全球女性保養品市場呈現穩定成長，雖然保養品以往都被視為屬於「女性領地」的產品，但全球男性保養市場不僅從2012年起就持續成長，未來前景也是相當看好。 有別於以往以性別（sex）做為市場區隔，消費者的性別認同及性傾向，已逐漸被用於區隔目標消費者，且同性戀消費者更因為其相較於一般異性戀男性的消費能力較強，而被視為「夢幻市場 （Dream Market）」。然而，現今台灣在該領域相關的研究文獻，卻往往只探討生理性別，忽略生理性別和性別認同之間的落差，如此將導致與性別相關的行銷研究有扭曲或偏頗的現象。 因此本研究希望能將性別認同與性傾向等因素，納入研究消費者購買保養品行為之考量因素，彌補理論和實際狀況的落差，期能研究出不同性別認同、性傾向的消費者，對不同定位保養品購買意願的差異，並根據該研究結果，給予保養品廠商一些行銷上的建議，讓其在釐清品牌定位時更有方向，並以更有效率、更適切的方式與顧客溝通。 本研究將影響保養品的購買意願從「性別認同」、「性傾向」、「獨特性需求」、「從眾行為」、「產品涉入」、「在意社會觀感程度」、「品牌知覺」、「品牌性別」、「品牌態度」等九大方面著手。 本研究以問卷方式獲取初級資料，收獲有效問卷共 375份，經過統計迴歸分析後發現，「性別認同」、「在意社會觀感程度」、「品牌知覺」和「品牌態度」此四項，最顯著影響消費者購買保養品意願。另外，雖然「性傾向」並沒有對購買意願產生影響，但卻有可能透過「在意社會觀感程度」干擾購買意願。而還有其他顯著影響因素待於研究中一一闡述。 / Recently, the global market of female skin care products has grown a steady pace. Although, the skin care products are usually regarded as female products, the global market of male skin care products has grown fastly since 2012 and market analysts are optimistic about its future. In the past, we usually only use “sex” to segment a market, but gender identity and sexual orientation are gradually used to target customers now. Moreover, gay customers are regarded as a “Dream Market” because they have greater purchasing power than heterosexual men do. However, existing studies still tend to probe into sex and neglect the differences between sex and gender identity. Therefore, this research takes gender Identity and sexual orientation into consideration when conducting the behavior of purchasing skin care products, and the dependent variable” purchase intention” is leveraged by “Gender Identity”, “Sexual Orientation“, “Product Involvement”, “Need for Uniqueness”, “Conformity Behavior”, “the Degree of Concerning with Social Perception”, “Brand Attitude”, “Brand Gender”, “Brand Perception”. Among influential factors, “Gender Identity”, “the Degree of Concerning with Social Perception”, “Brand Attitude”, and “Brand Perception” contribute significantly to purchase intention. Although sexual orientation does not lead to purchase intention, it may affect purchase intention through influencing the factor of “the degree of concerning with social perception”. Other factors affecting the behavior of purchasing skin care products will be further discussed in this research.

在關於政黨認同的研究中，除了明白表示出政黨認同的這群人之外，其餘沒有明白表示出政黨認同的選民，通常被歸類為所謂的「中立無反應」者，或是「獨立選民」。然而，這群沒有明白表示出政黨認同或投票對象的受訪者是否真是中立或無反應者，抑或真是獨立選民呢？葉銘元（1994）針對我國的獨立選民曾做過相當詳細的研究，本文接續其研究，選擇政治大學選舉研究中心的面訪資料，針對1989年至1999年間我國獨立選民的發展與變遷情形，分別就「我國獨立選民政黨認同及社會背景的發展與變遷」、「我國獨立選民政治涉入的發展與變遷」、「我國獨立選民投票取向的發展與變遷」及「影響獨立選民發展與變遷的因素」等方面作分析。 研究結果發現：我國獨立選民的比例雖然有下降的趨勢，但是近年來此種趨勢似乎有逆轉的情形，且獨立選民比例的高低的確會受到選舉制度不同的影響。獨立選民的社會背景也和政黨認同者有差異，他們的政治涉入較政黨認同者為低，對候選人及政黨評價較低，對議題保持中立的立場，投票時比較會考量候選人的條件優劣，較不會依政黨界限投票。與此同時，我們也發現獨立選民的組成上是由政治知識及政治涉入較低的「冷漠型獨立選民」，逐漸轉變為政治知識及政治涉入較高的「理想型獨立選民」。 在未來的發展趨勢上，我們發現新世代及新新世代選民中獨立選民所佔的比例是較低的，因此我們可以預期，獨立選民的比例應該還有下降的可能性。在民主化的進程繼續推展，政黨政治日益成熟穩定之後，我們預期有政黨認同的選民會呈現增長的趨勢，與此同時，獨立選民並不會大幅度的減少。基於獨立選民是理想公民的期待，我們相信還是會有一定比例的民眾認為自己是獨立選民，但正如同我們觀察到的，此時的獨立選民將不再是對政治一無所知，或是對政治冷漠的冷漠型獨立選民；而將成為對政治保持高度關注，並能依自己客觀的態度做出政治決定的理想公民。 / In most studies about party identification, people who do not clearly indicate their party identification are usually classified as so「neutral non-respondents」or 「Independents」. Are these respondents really neutral or non-response, or are they really independents ? Yeh Ming-Yuan (1994) has done detailed research on independent voters in Taiwan. This thesis follows his research, using individual level survey data to analyze the developing and changing situation of independent voters in Taiwan from 1989 through 1999. In particular, this thesis examines changing party identification and social background of independent voters, changing political involvement among independent voters, changing vote intentions of independent voters, and the facts which have influenced the develop of independent voters. Our research outcomes have shown that although the percentage of independent voters in Taiwan has declined, in recent years this trend seems to have reversed, The percentage of independent voters has actually been influenced by changes in the electoral system. There are differences in social background between independents and party identifiers. The degree of political involvement of independent voters is lower than that of party identifiers. Their evaluation of candidates and parties is also lower than those of party identifiers. They tend to stay neutral to all political issues when making their voting decisions, they tend to consider the conditions of the candidates, rather than voting by the boundary of parties. However, we also discover that independent voters are gradually evolving from "apathetic independent voters", with lower political knowledge and lower political involvement, to "ideal independent voters", with higher political knowledge and higher political involvement. Looking to the future, we discover that the percentage of independent voters in the next generation and the generation after that are much lower. Hence we can predict that the percentage of independent voters will likely decline. With the continuing development of democracy and the increasing maturity and stability of party politics, we expect that the percentage of party indentifiers will grow. However, this does not necessarily mean that the percentage of independent voters will decline dramatically.Because of the expectation that independent voters are the ideal citizens, we believe that there are still a certain percentage of people who will consider themselves as independent voters. Hence, independent voters increasingly will not be "apathetic independent voters" who know nothing about politics. On the contrary, they will become "ideal citizens" who keep highly concerned about politics and make political decisions according to their own subjective attitudes.
