本研究旨在探索使用者對網路媒體的認知圖像，選擇「PChome個 人新聞台」作爲整體觀察對象。本研究採「電子問卷調查法J，並以立 意抽樣，找出積極參與網路個人媒體活動的使用者。研究發現，使用 者的網路媒體認知圖像包含四個層面：（1)「個人控制與參與權」； (2)「人際溝通工具性」；（3)「大眾傳播特性」；（4)「雙向傳播 性」。研究發現，「個人控制與參與權」最受使用者重視，解釋程度最 高。最後，研究者提出「網路媒體混合模式」：網路呈現一種大眾傳 播、人際溝通與個人媒體三種傳播模式匯集的多元混合媒介。它整併 「個人與大眾」、「個人與人際」，以及「大眾與人際」傳播的效果，同 時，又重視使用者，讓其參與媒體活動，形成「個人經營媒體」的特 色，相較大眾「接收」模式，又屬於創新效果。這些效果，經由使用 者的網路認知展現，重視使用者與媒介之間的緩衝體（心理誨知結果），代表了網路使用者對「何謂網路媒體」的主觀圖像。
