摘要 廣告是企業與消費者之間一項重要的溝通工具,尤其在健康食品廣告中,品牌形象與代言人類型扮演不可忽略的角色。因此,本研究主要目的在探討品牌形象、廣告代言人類型與消費者購買意願之間的關係。 研究採2×2×2×2因子設計,以品牌形象與廣告代言人類型為自變數,消費者的知覺風險及產品知識為干擾變數,探討對消費者態度與購買意願之影響。 主要研究結果如下: 1.產品品牌形象對消費者產品態度有顯著影響(F=11.263,P<0.01),廣告代言人類型對消費者產品態度有顯著影響(F=32.314,P<0.01),且產品品牌形象與廣告代言人類型之間交互作用對消費者產品態度也有顯著影響(F=16.640,P<0.01);進一步分析發現唯有在廣告產品屬於高品牌形象前提下,廣告代言人類型才能有效對消費者產品態度有顯著影響。 2.產品品牌形象或廣告代言人類型對消費者產品態度的影響,皆未顯著受到知覺風險干擾。 3.主觀或客觀產品知識皆未顯著干擾產品品牌形象對消費者產品態度的影響;但主觀或客觀產品知識皆顯著干擾代言人類型對消費者產品態度的影響。 4.消費者產品態度對購買意願有顯著正向影響關係。
