本研究主要探討在競爭白熱化的服務業中，業者在既定服務下該如何突破重圍，制定有別競爭者的策略，以吸引且留住顧客。藉由檢視顧客所感受到的關係利益，透過感激與關係承諾的中介效果，進而促進再購意願，本研究著重於顧客確實感受到的利益為何，並且透過心理層面的感激情感面與關係承諾的兩個中介變數，影響顧客的再購意願。本研究透過討論顧客實際感受到的關係利益，會讓顧客回饋給企業，並且願意維持關係，進一步提出避免組織資源浪費並做改善制定，以讓企業了解所投入的資源達有效配置。
本研究以一般消費者為對象，以驗證所建構的研究模型。問卷共回收290份問卷，有效問卷共計253份。信、效度方面，所有變數均達一致與有效程度，在模型方面，所建構模型具一定的配適度。
透過結構方程式與迴歸分析方式進行實證分析，研究結果發現，顧客感受到的關係利益會對感激與關係承諾有正向影響，而感激與關係承諾皆與再購意願有正向影響；顧客感受的信心利益對於再購意願的總間接效果最大，其次為社會利益；加入感激情感的Morgan and Hunt(1994)延伸模型，對於再購意願的解釋力獲得提高。
