現今，隨著資訊、通訊科技的發展，企業與用戶之間的互動變得更加容易。因 此，許多企業紛紛建立了線上用戶創新社群(Online User Innovation Community)， 讓用戶去為企業現有的產品及服務提供建議，甚至是參與到新產品及新服務開發的 流程中。雖然過去許多線上社群之相關研究都有探討用戶知識協作的動機是如何促 使他們進行知識協作，然而關於知識分享或知識協作本身對於發想品質(Idea Quality)的影響之探討反而比較少。因此，本篇研究目的是試著從用戶角度進一步 去探討不同的知識協作方式對於發想品質的影響。
本研究採用實驗分析法去模擬線上社群的用戶進行知識協作的情境去進行實驗 分析。實驗的對象為國立成功大學企業管理學系某門課程的 40 位碩士班的同學在觀 察時間 10 週內在線上課程的通訊群組中進行「組內」和「組間」知識協作並由 6 位 專業人士去對每組在 10 週內於線上提交的想法進行評分。研究結果顯示，兩個研究 假設皆成立，表明組內知識協作及組間知識協作分別與發想品質之間皆呈現顯著倒 U 關係。因此，建議企業在利用這些線上用戶社群時可以留意組內知識協作與組間 知識協作之間的平衡。

Nowadays, many companies have established Online User Innovation Communities (OUIC) to engage users to provide suggestions, and even to participate in the new product and service development. Although past researches on online communities have discussed how the motivation of users motivates them to collaborate, however, the effects of knowledge sharing or knowledge collaboration on Idea Quality are rarely researched. Therefore, the purpose of this study is to further discuss the effects of different knowledge collaboration approaches on Idea Quality.
An experiment was conducted to simulate the knowledge collaboration situation in an online community. The experiment was conducted with 40 students from a master's course in the Department of Business Administration at National Cheng Kung University during an observation period of 10 weeks. The results showed that significant inverted-U relationships between intra-group and inter-group knowledge collaboration and idea quality, respectively. Therefore, it is recommended that companies should consider the balance between intra-group and inter-group knowledge collaboration when leveraging these online user communities.
