ABSTRACT A comprehensive review of the information systems literature suggests that the traditional perception–intention–usage framework may be deficient in explaining post-adoption behaviors. As an effort to fill this gap, the current paper presents a new theory – the theory of need for information systems (TNIS) – and introduces two new constructs – need for technology and need for information. Drawing on the needs-based perspective on behaviors, TNIS conceptualizes these two need constructs as the key predictors of continuance intention and usage. The current paper also discusses useful insights, important implications, and an appropriate instrument for measuring the two new constructs. This study thus contributes to a novel framework to advance theoretical understanding of post-adoption behaviors and to direct future research toward new avenues.

更好地理解采用后行为的新方向：信息系统需求理论

摘要 对信息系统文献的全面回顾表明，传统的感知-意图-使用框架在解释采用后行为方面可能存在缺陷。为了填补这一空白，本文提出了一种新理论——信息系统需求理论 (TNIS)——并引入了两个新的结构——技术需求和信息需求。利用基于需求的行为视角，TNIS 将这两种需求结构概念化为持续意图和使用的关键预测因素。当前的论文还讨论了有用的见解、重要的影响以及衡量这两个新构念的合适工具。
