摘　　要：分析了企业信息化环境下人-信息系统交互效率的重要性,提出将工作记忆、认知技巧、计算机自我效能感作为度量人的信息加工能力的3个维度,用实验的方法研究人的信息加工能力对人-信息系统交互效率的影响。用SPSS软件对实验数据进行统计,回归分析的结果表明:在技能型任务中认知技巧是影响交互效率的主要因素;在规则型任务中工作记忆是影响交互效率的主要因素;在知识型任务中工作记忆对交互效率有影响,但并不显著;在总体任务中工作记忆、计算机自我效能感是影响交互效率的主要因素。The essentiality of human-information system interaction efficiency was analyzed under the computerization environment of enterprises. Information processing ability was measured from three dimensions： working memory, cognitive skill, and computer self-efficacy. The experimental method was used to study the influence of information processing ability on human-information system interaction efficiency. Multiple regression results show that cognitive skill is the main factor influencing interaction efficiency for skill-based tasks, working memory is the main factor for rule-based tasks, and working m.emory has no significant influence on interaction efficiency for knowledge-based tasks. Working memory and computer self-efficacy are the main factors influencing interaction efficiency for total tasks.
