網際網路普及背後孕育著龐大商機，但電子商務仍然面臨商業競爭與來自消費者的挑戰。研究者認為引進品牌權益的概念，協助電子商務經營者建立強勢網路品牌，是一可行辦法。回顧文獻，發現過去顧客基礎品牌權益研究多半為行銷者導向，較少重視消費者個別差異。為了更進一步區分消費者的差異，研究者欲藉由使用與滿足理論對媒體使用動機的研究成果，來瞭解消費者在不同的使用動機下其重視的網路品牌權益構面。本研究以Aaker(1996)提出的品牌權益為基礎，並使用網路消費者為研究對象，建構顧客基礎的網路品牌權益構面。也一併瞭解消費者個別差異，作為電子商務經營者在發展電子商務時的重要參考依據。 本研究分四階段進行。第一階段為定義何謂網路品牌；第二階段透過焦點團體，發展出顧客基礎的網路品牌權益內涵；第三，透過第一、二階段的成果，進行網路品牌權益問卷編製與大樣本施測，確立顧客基礎的網路品牌權益構面。第四階段使用典型相關分析，以瞭解不同使用動機下的消費者，是否重視不同網路品牌權益概念。網路品牌權益量表透過線上調查，收集358份有效問卷。研究結果指出，網路品牌權益可分作五大構面，分別為網站管理（包含營運方式與互動關係）、品牌忠誠（包含使用偏好與使用習慣組成）、品牌聯想、自我表達及知覺品質，因素負荷量達52.77%；量表共33題，信度.905(p<0.01)，效標關連效度達.512(p<0.01)。本研究亦發現在不同網路使用動機之下，消費者重視的網路品牌權益不同；在資訊蒐集與娛樂動機下，消費者重視網路品牌的網站管理與知覺品質；在人際與娛樂動機下，則重視知覺品質與自我表達。 最後則對電子商務業者提出品牌經營參考，及未來學術發展方向。 關鍵字：品牌、網路品牌權益、顧客基礎、使用與滿足。 / Despite the universal availability of the Internet and the immense business opportunities generated e-commerce, e-commerce itself is confronted by endless business competition and consumer mistrust. How should e-commerce managers react to these competition and challenges? This research proposes that the introduction of the brand equity concept is viable in helping e-commerce managers establish strong online brands, yet existing literature on customer-based brand equity are mostly marketer oriented rather than customer oriented, thus not much weight is given to individual consumer differences. We use mass media theory “uses and gratification” theory to understand if customer have different internet use motivation will cause them prefer different online brand equity. We use online consumer as research participant, and build customer-based online brand equity construct, describe individual differences as our results. E-commerce managers can utilize as important reference when developing their business affairs. This research is conducted in four stages: the first stage is intended for understanding consumers’ definition of online brands; the second stage develops preliminary customer-based online brand equity constructs via focus groups; the third stage develops customer-based brand equity constructs by designing and testing a survey based on the results of the first two stages using large samples; and the fourth stage uses canonical analysis to find out whether customer have different internet use motivation will cause them prefer different online brand equity. We collected 358 validate questionnaires. Findings indicate that online brand equity can be divided into five dimensions: web site management, brand loyalty, brand associations, self expressions, and perceived quality. Totaling 33 items, factor loading 52.77%, with 0.905 in reliability and 0.512 (p<0.01) in criteria-related validity. When conusumer’s internet use motivation is search information and entertainment, the online brand equity construct they will prefer is web site managemet and perceived quality. But when conusumer’s internet use motivation is interpersonal and entertainment, the online brand equity construct they will prefer is perceived quality and self expressions. According results above, we propsed some recommdations for e-commerce managers and scholars. Keywords: Brand, Online brand equity, Customer-based, Uses and gratification
