在Web2.0的浪潮下，網路購物者越來越習慣主動搜尋商品資訊、發表產品心得。2007年資策會的調查顯示，有八成的網友在購物前會先上網瀏覽商品評鑑、七成以上的網友會受到部落格評價或評比影響購物意願。這證明了網路口碑深深影響消費者的購物行為，身為網路商店的經營者，不可不重視這股影響力。 對於網路化妝品商店來說，其所販售的產品屬於經驗性商品，消費者在無法透過實體商店進行試用的情況下，相當依賴網路口碑了解產品資訊與效果；此點從國內最大的口碑社群網站 「FashionGuide」與「UrCosme」皆以化妝品使用心得為討論主題即可窺知。並且，觀察到國內網路化妝品網站多半設計有「使用心得分享」的機制，顯示大部分的業者都認為在網路上放上使用者的心得，將對於產品銷售有所助益。 以上可知，網路口碑對於消費者的購買決策具有相當的影響力，並已逐漸被應用在網路商店的經營上。然而國內外針對網路口碑的研究多半偏重在消費者行為方面，從企業觀點看待網路口碑管理的相關研究非常少數。本研究試圖探索網路化妝品商店進行網路口碑管理之動機與作法，提供實務上與學術上的貢獻。 本研究的研究問題有四：1.網路化妝品商店進行網路口碑管理的動機為何？2.網路化妝品商店如何監視網路口碑？ 3.網路化妝品商店如何回應網路口碑？4.網路化妝品商店如何促進網路口碑傳播？ 透過深度訪談三家國內網路化妝品業者，並配合相關的次集資料蒐集與整理，本研究獲得以下主要結論：1.網路化妝品商店進行網路口碑管理的動機為獲知市場資訊與提升品牌認同感。2.網路化妝品商店利用美容討論網站與品牌網站監視網路口碑，根據細節內容界定其參考價值。3.網路化妝品商店會選擇性回應負面網路口碑；回應重點為情緒安撫、表示負責。4.網路化妝品商店藉由「心得分享」式顧客推薦方案、美容知識傳遞與促銷活動促進網路口碑傳播。5.網路化妝品商店所設計的網路口碑回應機制，有助於網路口碑監視與傳播促進。 在網路口碑管理理論方面，本研究的主要貢獻有三：1.彌補網路口碑回應與傳播促進的研究缺口。2.提供網路口碑管理研究者模型修定之考量。3.發現網路口碑與傳統行銷廣告的新關聯性。 / Entering Web 2.0, online shoppers are more used to search product information before purchasing and share their comments after shopping.
