協同消費一詞為Rachel Botsman 在2010年的TED Talk中提出，其為傳統的分享消費方式和網路科技結合下的產物。拜金融風暴導致經濟蕭條之賜，此模式便利且省錢的特質在歐美掀起了一波熱潮。協同消費在歐美地區早已不陌生，然而對於亞洲國家而言仍是新鮮的科技。
目前國內消費者較熟知的協同消費科技為Uber，但對於協同消費的熟悉與接受程度尚欠缺調查。學術上，雖有外國學者針對協同消費的各面項討論，然而對於台灣消費者是否接受此科技模式仍未有學者提出相關研究。有鑑於此，本研究將針對台灣消費者對於協同消費模式接受度之關鍵影響因素進行探討。
本研究使用TAM之延伸模型為研究架構，此模型為原始TAM模型與信任和TPB理論中變項的結合。透過此模型，本研究將探討三個問題：一、瞭解協同消費之使用者接受協同消費模式的態度與意願之關鍵影響因素；二、瞭解信任對於協同消費使用者之認知行為控制、主觀規範與使用態度之影響；三、驗證延伸信任與TPB之科技接受模型是否適用於其他電子商務科技，如協同消費模式。
經由研究結果的分析，本研究期望能找出影響台灣消費者對於協同消費模式接受度之關鍵因素，進而提供業者更精確的消費者特性以利其進行更精準的行銷。

“Collaborative Consumption (CC)” was created by Rachel Botsman who made a speech at TED Talk since 2010. This technology is the combination of traditional sharing consumption and internet platform. CC has a great vogue due to its convenience and characteristic of saving money since financial crisis of 2007–08. This concept has already fitted in European’s and American people’s life, but for Asia, it is still a new technology which needs promotion to let customers know it.
At present, the most popular CC’s technology is Uber. Even Uber is a famous name between Taiwan consumers, it still needs the investigation to realize customer’s acceptance. Academically, though foreign scholars have discussed lots of CC’s aspects, it still needs someone to study Taiwan consumer’s acceptance toward CC. Hence, this study will focus on factors which will affect Taiwan consumer’s intention toward CC.
This study use extend TAM as research model, this model is the combination of original TAM and trust & TPB’s variables. We can study three questions as blow through this model: 1.To realize Taiwan consumer’s acceptance toward CC; 2.To realize an effect of trust toward CC user’s PBC, SN and attitude; 3.To prove whether “An extension of Trust and TAM model with TPB” which created by Wu and Chen (2005) can be used to other e-commence, like Collaborative Consumption.
After research analysis, this study hopes to find the key reason which affects Taiwan consumer’s acceptance toward CC and further provide trader more accurate consumer’s characteristic to let marketing more precise.
