本研究探討報紙之延伸產品（網站）與母品牌優勢對母品牌態度的影響。本研究採實驗 法，研究結果發現，相較於未導入延伸產品，報紙之高契合延伸產品的推出會提升消費 者的母品牌態度，低契合延伸產品則會降低消費者對該品牌的態度。本研究結果亦顯 示，品牌優勢會影響報紙媒體推出高、低契合延伸產品時，消費者所產生之母品牌的態 度。本研究建議報紙在推出延伸產品時，若欲提升消費者對母品牌的形象與態度，首重 考量延伸產品與原報紙形象的契合度，避免低契合產品之推展，提高品牌優勢，才能以 強化品牌的價值。

This research studies effects of extended products introduced by the press and the dominance of the parent brand on the attitude toward parent brand. Experimental results indicate that, compared to the time that no extended prcxluct exists, brand extensions of high fit significantly enhance readers' brand attitude toward a newspaper. Brand extensions of low fit have significant negative reciprocal effects on brand attitude. In addition, brand dominance influences effects of extensions of good fit and effects of extensions of poor fit on consumers' parcnl brand altitude. This research suggests that newspapers should first consider the fit between extended products and brand image when the press introduces brand extensions. Poor extensions should be avoided and brand dominance should be enhanced to strengthen brand value.
