在過去十年中，購物環境最引人注目的趨勢之一，即是消費者可與日益增加的通路零售商直接互動。由於科技與網際網路的發展，使得消費者從原本被動的接收電視廣告，轉變為可主動選擇、過濾、接收網路廣告的角色。再加上網際網路不如電視的普及，而網路購物也不似電視購物有專人為產品作說明。因此，這種專為購物所設置的電視購物頻道與購物專家自此應運而生。為了瞭解觀眾在購物臺的涉入度、對購物專家的信任、購物專家吸引力、購物臺形象與購買意願之間的關係。本研究藉由問卷調查法來探討觀眾如何受涉入度、購物專家吸引力、信任與購物臺形象所影響，從而改變其對電視購物之購買意願。研究結果顯示，觀眾對電視購物的涉入度、購物專家吸引力、信任與購物臺形象會直接影響其購買意願，而對購物專家的信任則對購物臺涉入度與購買意願之間具有顯著的中介作用。最後，本研究更進一步提出具體建議，以供相關業者作為改善、提升觀眾購買意願之依據。
