本研究探討正向心情如何影響消費者品牌延伸的評價，並整合心情對相似性及評價判斷效果之品牌延伸研究。實證結果顯示在窄品牌下，正向心情主要提昇核心品牌中距延伸的延伸評價(相對於近距延伸與遠距延伸)；在寬品牌下，正向心情主要提昇核心品牌遠距延伸的延伸評價(相對於近距延伸與中距延伸)；並發現正向心情對延伸評價的影響過程中，核心品牌及其延伸間所知覺的相似性以及公司推出延伸產品的能力扮演中介角色。

This research examines how positive mood influences consumer evaluations of brand extensions in varied brand breadth cases. Previous researches have found that the effect of mood on similarity and evaluative judgments influence brand extensions. Findings show that the facilitating influences of positive mood on perceived similarity, perceived competency, and brand extension evaluations are the greatest for moderate extensions than for either near or far extensions with a narrow brand. Moreover, the facilitating influence of positive mood on perceived similarity, perceived competency, and brand extension evaluations are the greatest for far extensions than for either near or moderate extensions with a broad brand. In both conditions of brand breadth, the results are showing that both perceived similarity and perceived competency strongly mediate mood's influence on extension evaluations. Instead of influencing evaluations directly, similarity is more important because it provides a basis for inferring competency that, in turn, determines extension evaluations. Implications of these findings for managers and suggestions for further research are presented.
