臉書社群是近幾年比較熱門的研究主題，而與資訊分享相關之研究，也較多以臉書社群為例，且亦有部份研究成果，然而深入其中探討社會支持、分享態度與主觀規範等對資訊分享意圖影響的相關研究較為缺乏，因此，本研究將以臉書社群使用者做為研究對象進行探討。 本研究以社會支持與理性行為理論作為研究基礎，主要目的在於瞭解臉書社群使用者現況與資訊分享意圖，探討社群使用者社會支持、分享態度與主觀規範之感受度，對於資訊分享意圖之間的關聯性。研究方法採用量化之問卷調查方式，本研究結果歸納如下： 1.臉書使用者在社會支持感受程度上，受到年齡、教育程度以及使用行為變數（接觸臉書時間、平均一天瀏覽時間）影響。 2.臉書使用者在分享態度感受上，僅受到教育程度的影響。 3.臉書使用者在主觀規範感受上，受到年齡、教育程度與平均一天瀏覽時間影響。 4.臉書使用者在資訊分享意圖行為表現上，未受到使用行為變數之影響，但受到年齡與教育程度影響。 5.臉書使用者在分享態度、主觀規範的感受與資訊分享意圖皆呈現顯著且正向影響。 The subject of research probing into the social networking websites is more popular in recent years.
