IT use is the fundamental construct of IS research. However, despite its centrality, the literature lacks agreement on the nature of the construct and its antecedents, which has led to a fragmented nomological network. We provide a comprehensive review of the existing empirical IT use constructs, analyze their overlaps, and distill them into three dominant constructs: adoption, static IT use, and innovative IT use. We then develop an overarching framework for extant IT use research by developing a holistic model. Each IT use construct has its own set of organizational and technological antecedents as well as psychological drivers. Our model synthesizes existing research and is empirically validated using a web-based survey of business technology users. These findings resolve issues in the conceptualization of IT use, integrate the fragmented IT literature, and help avoid the illusion of knowledge accumulation. The outcomes of the paper provide guidelines for researchers on the conceptualization of IT use as well as for practitioners regarding purposeful use-based design. Areas for future research in IT use are also recommended.

IT 使用是信息系统研究的基本构建。然而，尽管它具有中心地位，但文献对这一概念及其前因的性质缺乏共识，这导致了一个支离破碎的法理网络。我们对现有的实证 IT 使用结构进行了全面回顾，分析了它们的重叠部分，并将其提炼为三个主要结构：采用、静态 IT 使用和创新 IT 使用。然后，我们通过开发整体模型，为现有 IT 使用研究建立一个总体框架。每个 IT 使用结构都有自己的一套组织和技术背景以及心理驱动因素。我们的模型综合了现有的研究，并通过基于网络的商业技术用户调查进行了实证验证。这些发现解决了IT使用概念化的问题，整合了碎片化的IT文献，并有助于避免知识积累的错觉。该论文的结果为研究人员关于 IT 使用概念化以及从业者关于有目的的基于使用的设计提供了指导。还推荐了 IT 使用的未来研究领域。
