近年臺灣外食消費市場擴張，其中尤以連鎖速食業之營業額及擴展店數居臺灣餐飲業別之冠，外食族群年齡有年輕化的趨勢。消費者在購買決策前會將與餐廳相關的屬性分級成不同的重要程度，並影響所感受的價值。儘管探討屬性及價值的研究也不少，但對於價值的界定模糊，且屬性對於享樂及功利價值，以及享樂、功利價值對於行為意圖之關係仍不明確。因此本研究將以Y世代消費族群為研究對象，探討連鎖速食餐廳屬性、享樂功利價值及行為意圖變數間之關係。本研究於2月1日至2月29日發放網路問卷，回收468份有效問卷。研究結果將餐屬性分為：便利性及設施、餐點價值與推廣行銷、用餐環境衛生安全、服務與客訴處理四類。餐廳屬性分別正向影響享樂及功利價值，享樂價值較功利價值更能影響行為意圖。本研究驗證變數間之因果關係，並提出實務建議。
