平台的興起改變了傳統消費模式，因此無論是在學術界或是實務界，強調互動的社群商務在近年來都漸漸受到重視。然而，從社群中內容經營者的角度出發探討社群商務經營狀況的相關研究不多；此外，社群商務與網路外部性的連結也相對缺乏，故本研究欲以台灣影響力最大之社群平台Facebook的粉絲專頁為例，探討社群商務「使粉絲變成消費者」的流量變現過程，供未來社群商務經營者參考。 本研究以學者Hagel & Armstrong（1998）提出的會員發展四階段作為研究架構，採個案研究法，選擇「傑利帶路 玩世界」與「I’m 布布媽咪／Chic KimBlake」為個案，透過深度訪談探討選擇個案從內容社群至社群商務的經營過程中，每一階段形成正向網路外部性的關鍵成功因素以及做法，並同時分析不同的訴求類型於粉絲專頁上的影響與效果。 研究結果顯示，在社群商務的整體經營中，人格力、社群力以及產品力為三大關鍵成功因素，並且依序在吸引會員（製造流量）、增加參與（集中流量）、建立忠貞（鎖住流量）三階段扮演關鍵角色，最終實現價值獲取（流量變現）的目的；除此之外，感性的訴求在社群商務前期扮演相對重要的角色，而訴求的有效性與社群商務提供的產品與服務類型並無直接相關。 / The new economics of platform changes traditional purchase process and reconstructs value chain, giving the market new business rules.
