人-信息系统交互效率影响因素及其作用机理

分析了企业信息化环境下人-信息系统交互效率的重要性，从定义、特征及评价等方面研究了人-信息系统交互效率的内涵，从因素属性的角度将影响人-信息系统交互效率的因素分为5类：人的因素；信息系统因素；管理因素；环境因素和技术因素．据此，提出了人-信息系统交互效率影响因素概念模型，讨论了模型中各类因素对于人-信息系统交互效率的影响机理．分析表明：作为模型核心构成的人的因素和信息系统因素直接决定交互效率的高低；管理因素约束或支持人和信息系统的效用，最终保障交互效率；而环境因素、技术因素通过制约或支撑人的因素、信息系统因素对交互效率产生问接影响．

Influencing Factors and the Concept Model of Human-information System Interaction Efficiency

The importance of human-information system interaction efficiency within enterprise informationization environment is analyzed.The intension of human-information system interaction efficiency is studied from definition,characteristic and evaluation.According to different properties,the influencing factors of human-information system interaction efficiency are divided into five kinds,including human factor,information system factor,management factor,environment factor,and technology factor.On this basis,the concept model of human-information system interaction efficiency is brought forward,and mechanisms of influencing factors to human-information system interaction efficiency are discussed in the model.The analysis indicates: As the core parts of the model,human factor and information system factor determine interaction efficiency directly.Management factor restricts or supports efficiency of human and information system.Environment factor and technology factor bring indirect influence to interaction efficiency by restricting or supporting human factor and information system factor.
