This study is mainly focused on brand extension elements. This study is classify brand extension elements into brand associations (brand typicality, brand salience and brand dominance) and extension fitness (features similarity, usage similarity, concept similarity and goal similarity). This study investigated effects of brand fitness elements and brand associations on purchase intention of extension products. The main results of this study is following. First, the extension fitness elements (feature similarity, usage similarity, concept similarity and goal similarity) have influenced significantly on purchase intention of extension products. And typicality and salience of brand associations have influence significantly on purchase intension of extension products, but dominance of brand associations have not influence significantly on purchase intension of extension products. Second, brand concept similarity have the most influence on the purchase intention of extension products. Feature similarity, usage similarity and goal similarity have influenced almost equally on purchase intension of extension products. And typicality of brand associations have more influence than salience of brand associations on purchase intension of extension products. Third, Brand concept consistency have the same vector with extension products purchase intention in MDS analysis. Fourth, the brands used in this paper are much popular so maybe consumers think extension products are real existence. If it is real the results are too much reflect mother brand power. In past papers presented significant difference of interaction effects of feature similarity and concept consistency, feature similarity and goal congruency and concept consistency and goal congruency on brand extension. Feature similarity affected more low concept consistency than high concept consistency on purchase intention of brand extension. Also, feature similarity affected more low goal congruency than high goal congruency on purchase intention of brand extension. But concept consistency affected more high goal congruency than low goal congruency on purchase intention of brand extension. And in the other view point, as past paper, participants did not present significant difference in purchase intension of brand extension according to degrees of feature similarity, concept consistency and goal congruency. Concept consistency did not affect on purchase intention of brand extension in low goal congruency. Concept consistency affected on purchase intention of low feature similarity but did not affect on purchase intention of high feature similarity in high goal congruency. Feature similarity did not affect on purchase intention under high concept consistency and high goal congruency. Goal congruency facilitated more concept consistency than feature similarity in brand extension. Finally we have similar research and papers. But the results are don't have same or similar result. Besides a certain paper show reversw result. So we have to fulfill following research in these themes. After making and controlled result, the papers about brand extension are more useful and worth.
