本研究企圖透過對網路援交的瞭解，發現網際網路促成援交興盛的原因：包括電腦的方便、隱匿、與逃避等特性，和網路社會的人際關係為一種弱紐結、具有去個人化的現象，形成越常使用電腦者因為工具的接近性越容易產生援交行為；此外，電腦網路帶來公、私領域混淆，造成自我與他者的難辨，主體理性批判能力下降也是原因之一；同時加上外在環境性觀念的開放，資本家對語言符號和媒體的操弄，使得援交非但沒有因為是外來的流行現象而退燒，反而成了具有台灣特色的性文化一環。基於對重建台灣性文化與性觀念的關懷，認為時下常被提出的「主體消失」概念，若無妥善的理解將造成主體意義的喪失，進一步也無法形成集體的共識。至於本研究主張的「主體建構」是一種基於社會實踐的提論，強調主體理性，也認同主體間具形上的同一性，因為只有承認主體具有同一性，如此方能具有建構一個新的社會性價值或性觀念的可能。
