摘要: 【目的/意义】基于双路径模型(Elaboration Likelihood Model,ELM)探究互联网环境下用户跨平台学术信息
搜索行为的影响因素,假设用户在多平台学术信息搜索行为的过程中除了受到信息质量(中心路径)与信源可信度
(边缘路径)的影响外,还会受到感知有用性的中介作用以及注意力控制水平与信息自我效能的调节作用。【方法/
过程】通过建立学术信息搜索行为模型,采用问卷调查法收集到 350份有效样本,利用 SPSS 21.0进行数据分析,同
时对搜索模型的感知有用性、注意力控制水平及自我效能要素分别进行了中介效应与调节效应检验。【结果/结论】
结果发现信息质量或信源可信度对感知有用性的影响受到注意力控制水平的负向调节,且注意力控制水平对边缘
路径的调节更为显著,信息自我效能则能加强感知有用性对搜索行为的预测作用。【创新/局限】本研究从行为心理
的微观视角,将注意力控制水平引入双路径模型,为探究跨平台学术信息搜索行为提供新的研究路径。

Abstract: 【Purpose/significance】Based on the elaboration likelihood model, we investigate the factors influencing users' cross-plat-
form academic information seeking behavior in the Internet, and conclude that in addition to being influenced by information quality
(central path) and source credibility(edge path), users' cross-platform academic information seeking behavior it is also mediated by
perceived usefulness and moderated by the level of attentional control and information self-efficacy.【Method/process】A model of aca-demic information seeking behavior was developed. Then a questionnaire survey was conducted and 350 valid data were collected, and data were analyzed using SPSS 21.0. The mediating and moderating effects of perceived usefulness, attention control level, and self-ef-ficacy were examined.【Result/conclusion】The results found that the effect of information quality or source credibility on perceived usefulness was negatively moderated by attentional control level, and the moderating effect of attentional control level on the edge path-was more significant, while information self-efficacy enhanced the predictive effect of perceived usefulness on seeking behavior【. Inno-vation/limitation】From a micro perspective, the psychological level of attention control is introduced into the elaboration likelihood model to provide a new approach for exploring academic information search behavior.
