Abstract Since the underutilization of technology often prevents organizations from reaping expected benefits from IT investments, an increasing body of literature studies how to elicit value-added, post-adoptive IT use behaviors. Such behaviors include extended and innovative feature use, both of which are exploratory in nature and can lead to improved work performance. Since these exploratory behaviors can be risky, research has directed attention to trust in technology as an antecedent to post-adoptive IT use. In parallel, research has examined how computer self-efficacy relates to post-adoptive IT use. While such research has found that both trust and efficacy can lead to value-added IT use and that they might do so interdependently, scant research has examined the interplay between these antecedents to post-adoptive IT use. Drawing on the Model of Proactive Work Behavior with a focus on its predictions about trust and efficacy, we develop a research model that integrates trust in technology and computer self-efficacy in the post-adoption context. Our model suggests that the two concepts are interdependent such that trust-related impacts on post-adoptive use behaviors unfold via computer-related self-efficacy beliefs. Contemporary tests of mediation on data from more than 350 respondents provided support for our model. Hence, our findings begin to open the black box by which trust-related impacts on post-adoptive behaviors unfold, revealing computer self-efficacy as an important mediating factor. In doing so, this study furthers understanding of how, and why, trust matters in post-adoptive usage, enabling strategic change management by elucidating the “fit” between technological characteristics and post-adoptive usage.

信任对采用后的用法的影响方式和原因：内部和外部自我效能的中介作用

摘要由于技术的未充分利用通常会阻止组织从IT投资中获得预期收益，因此越来越多的文献研究如何引发增值，采用后的IT使用行为。此类行为包括扩展和创新的功能使用，这两种功能本质上都是探索性的，可以改善工作绩效。由于这些探索行为可能具有风险，因此研究已将注意力转移到对技术的信任，将其作为采用后IT的先决条件。同时，研究检查了计算机的自我效能如何与采用后的IT使用有关。尽管此类研究发现信任和功效都可以导致IT使用增值，并且它们可能相互依赖，但很少有研究检查了这些先行因素与采用后IT使用之间的相互作用。借助主动工作行为模型，重点是对信任和功效的预测，我们开发了一种研究模型，该模型在采用后的环境中将对技术的信任与计算机自我效能相结合。我们的模型表明，这两个概念是相互依存的，因此通过计算机相关的自我效能感信念，对信任相关的影响对采用后使用行为的影响得以展开。当代对来自350多个受访者的数据进行的调解测试为我们的模型提供了支持。因此，我们的发现开始打开一个黑匣子，通过它可以了解与信任有关的对收养后行为的影响，揭示出计算机自我效能感是一个重要的中介因素。这样一来，这项研究可以进一步理解信任在采用后的用法中的重要性，以及信任的原因，
