人事行政由傳統的人事管理轉變為人力資源管理，再藉由數位電子化，形成現今的人力資源資訊系統（WebHR），利用網路與電腦科技來進行人力資源管理活動的收集、存取及彙整，惟過去相關研究僅著眼於系統的接受行為。本研究則勾勒一個WebHR持續使用意圖的因果模型，首先站在系統使用者的角度來感受WebHR系統的設計品質，從而引發使用者的使用價值（易用性、有用性）評估，透過價值判斷來形成態度，進而塑造使用者的信任與滿意度，最後建構其持續使用意圖。研究結果顯示：系統設計品質正向影響易用性及有用性，進而造就正向的使用者態度，但易用性並不影響有用性。使用者態度有利於提升信任、使用者滿意度與持續使用意圖，信任亦造就使用者滿意度的增加，而信任及使用者滿意度也中介了使用者態度與持續使用意圖之間的關係。最後，管理意涵及未來研究建議亦被提出討論。

Personnel administration has changed from traditional personnel management to human resource management, and then the current human resource information system (WebHR) through digitalization is formed, which makes use of network and computer technology to collect, access and aggregate human resource management activities; however, the related research only focused on the acceptance behavior for the system. This study outlines a causal model of WebHR’s continuous use intention. Starting from the perspective of system users to perceive the design quality of the WebHR, it triggers the user’s evaluation of the use value (ease of use, and usefulness). Attitudes are formed through the value judgement, which in turn shape users’ trust and satisfaction, and finally construct their continuous use intentions. The research results show that system design quality positively affects ease of use and usefulness, which in turn creates positive user attitudes, but ease of use does not impact on usefulness. User attitude is beneficial to enhance trust, satisfaction and continuous use intention. Trust increases users’ satisfaction, and trust and users’ satisfaction also mediate the relationship between user attitude and continuous use intention. Finally, management implications and future research recommendations are also discussed.
