隨著企業電子化的迅速發展，企業紛紛建立專屬的企業資訊入口網站，隨著環境快速變化，企業資訊入口網站功能與特性也隨著科技變革推陳出新，因此，企業如何選擇、採納與使用，不僅影響企業營運，使用者滿意程度會影響使用成效，而系統選用的忠實程度也會影響使用者滿意度。
本研究以權變理論、鑽石模型與科技任務適配理論為基礎，來探討「科技相容度」與系統選用忠實度對企業資訊入口網站與個人使用者滿意度的影響。研究架構主要整合了三種不同的相容度，包括：科技與任務的相容度、科技與人的相容度、科技與組織的相容度。
本研究以實證研究的方法來聊解不同的相容度如何影響企業資訊入口網站的使用者滿意度的影響。我們以六個研究假設來驗證研究的架構，並以PLS進行檢驗。研究結果發現科技與任務的相同度對於企業資訊入口網站的使用者滿意度的影響程度最鉅，這意味著企業必須採用最符合任務需求的企業資訊入口網站。此外，科技與人的相容度對於企業資訊入口網站的使用滿意度有顯著影響，顯示科技若與使用者過去的使用經驗、價值觀等相容時，使用者滿意度更佳。另外，當企業資訊入口網站越相容於企業任務、個人與組織需求時，使用者使用系統的方法越忠實於系統原本設計目的也會提升使用者滿意程度。
總而言之，與過去研究僅針對單一相容度來探討，本研究具體提出整合性的相容度概念，研究結果發現不同類型的相容度對企業資訊入口網站的使用者滿意度有顯著影響。就企業而言，本研究貼近企業界實務需求，對使用者具有不同的價值與意義，可作為企業實施企業資訊入口網站時的參考依據。

Along with the rapid and continuing evolution of enterprise computerization, enterprise establishes Enterprise Information Portal (EIP) gradually. The function and property of EIP changing with complicated environment and technology. Thus, the way enterprise adopt and use the EIP will influence enterprise operating and users satisfaction of EIP and the faithfulness of appropriation of information system will influencing user satisfaction.
The goal of this research is to find the significant factors that link between the user satisfaction of EIP and faithfulness of appropriation by using diamond model and contingency theory. We combine with three distinct factors of compatibility, including (1) Technology–Task Compatibility (2) Technology–People Compatibility (3) Technology–Organization Compatibility, to build an integrated model.
An empirical survey methodology is applied to test the research model and six hypotheses are developed in this study, and then we use PLS to analysis it. The results reveal that Technology–Task Compatibility contributes most to the use of EIP. It implies that EIP should fulfill the task needs of users to promote user satisfaction. Moreover, Technology–People Compatibility implies that it will enhance the user satisfaction if the EIP is more compatible with user past experience and value. We also found that as EIP is more compatible with enterprise needs of tasks, and people, and the way user use EIP is more faithful with the purpose of the designer will promote user satisfaction of EIP.
