基于感知质量的企业内部网用户采纳模型研究

内部网是信息获取和知识共享的重要途径。为考察用户感知的内部网质量对用户采纳的影响,文章利用TAM和WebQual模型,设计了包含易用性、设计质量和信息质量三个维度的内部网质量测量模型,建立了包含内部网质量、感知有用性、主观规范和行为意图四个核心构念的内部网用户采纳模型。实证结果表明:该内部网质量测量模型具有良好的信度和效度;相比主观规范,内部网质量对用户采纳具有显著影响;感知有用性在内部网质量和用户采纳之间具有完全中介效应。

A Study on User Adoption Model of Enterprise lntranet Based on Perceived Quality

Intranet is an important medium for information accessing and knowledge sharing. In order to examine the impact of user perceived quality of intranet on user adoption, the paper designed a measurement model of intranet quality, which ineluded three dimensions, i.e. ease of use, design quality and information quality, and then developed a user adoption model of in tranet, which contained four core constructs, i.e. intranet quality, perceived usefulness, subjective norms and behavioral in tentions, based on the integration of TAM （Technology Acceptance Model）and WebQual （Web Quality Model）. The results from tile empirical analysis show that： the measurement model of intranet quality proposed by this paper has better reliability and validity; compared with subjective norms, intranet quality has a signifieant impact on user adoption; the effect of intranet quality on user adoption is fully mediated by perceived usefulness.
