虛擬桌面基礎建設( Virtual Desktop Infrastructure, VDI)是在中央控管的資料中心伺服器中管理桌面作業系統的虛擬化科技。組織要建置VDI，無論其規模大小，都涉及潛在的重大資訊基礎建設的投資，並且都是相對昂貴的。然而，組織採用VDI，因組織任務、特性及其文化，似有不同的考量。本研究以延伸整合型科技接受模式(Unified Theory of Acceptance and Use of Technology, UTAUT2)，結合任務科技適配模式(Task Technology Fit, TTF)整合為研究模型，並在成功推展VDI的組織中，以決策試驗與實驗分析法(Decision Making Trial and Evaluation Laboratory, DEMATEL)分析決策者對VDI的採用因素。其目的在於：
1.提出一套全面的VDI採用因素。
2.導出這些採用因素的因果關係。
本研究發現便利條件、任務特性、績效期望、任務科技適配4項因素，在VDI的採用決策中，屬於影響層面較廣的因子，也對行為意圖及使用行為造成了正面的影響，在組織中對這4個因素的內涵進行提升，可以改善VDI的採用環境，於採用後也可以獲得更多的使用行為。

VDI(Virtual Desktop Infrastructure) is a virtualization technoloty to manage desktop operation system in the centralize-managed data center server. It is relatively expansive to set the VDI up in the organization, no matter how many virtual machines in VDI. Therefore, organizations will consider different adoption factors depend upon it’s mission, character or culture for VDI adopt consideration. We integrate UTAUT(Unified Theory of Acceptance and Use of Technology) and TTF(Task Technoloty Fit) models as research models and take DEMATEL(Decision Making Trial and Evaluation Laboratory) to analyze the adoption factors of decision makers. In summary, The research goal were to:
1.Identyfy a comprehensive set of determinants for VDI adoption;
2.Derive the causal relationships among the identifyied determinants
The factors of Faciliate Condition, Task Characteristics, Performance Expactation, Task Technology Fit are proposed as influence factors in VDI adoption decision consideration. These factors influence other factors more than the others, and cause positive effect to Behavior Intention and Use Behavior. We can do something good to these factors to imporve VDI adoption preconditions, and get more use behavior after VDI was adopted.
