由於科技的進步突飛猛進及建構寬頻網路環境的完備下，人與人之間的溝通管道有了更多新奇的選擇，在幾乎人手一機智慧型手機當道的通訊軟體上，如今已演變成為現代人生活中必備的溝通、討論或分享的重要一環，甚至可能會影響到人際關係的問題，如何藉由持續性的服務創新來提高顧客的滿意度，並在良好的顧客滿意度情況下來強化顧客的忠誠使用度，這對於增加通訊軟體的活躍用戶人數將有莫大的助益。因此，本研究以台灣使用者在智慧型手機上最愛的LINE做為主要探討的app通訊軟體，來了解大專院校學生對於LINE之「服務創新」的看法，是否對於其「顧客滿意度」以及「忠誠度」等構面間有所影響。首先，將針對大專院校學生基本的人口統計變項在LINE之「服務創新」、「顧客滿意度」及「忠誠度」等三大構面上的差異性做一確認，再透過簡單迴歸分析法來檢驗大專院校學生對於LINE之「服務創新」與「顧客滿意度」兩構面間之影響性，以及其LINE之「顧客滿意度」與「忠誠度」兩構面間的影響性。研究結果發現：（1）性別及每日所花費在LINE通訊軟體上的時間長短，兩個人口統計變項，對於研究中所提三大構面的影響性是最大且顯著；（2）LINE之「服務創新」對「顧客滿意度」，及LINE之「顧客滿意度」對「忠誠度」兩關係上均呈現顯著的正向相關性，而前者的標準化相關係數（0.745）是小於後者（0.943）。期能藉由本研究在各構面問項之排序及顯著性的分析與結果，做為廠商日後在LINE之服務創新上的參考，以及提升其顧客滿意度與忠誠度的方向。
