智能手机用户信息安全行为意向影响因素的实证研究

摘要

This paper adds perceived threat and descriptive norms into Protection Motivation Theory(PMT)and con?structs the model of factors that influencing smartphone users'information security behavior.Then,the paper verifies the model through a questionnaire study and structural equation.The results show that perceived threat,response effica?cy and self-efficacy have a significant effect on smartphone users'information security behavior intention,response cost has no influence on behavior intention. Perceived vulnerability and perceived severity have indirect effects through perceived threat on smartphone users'information security behavior intention.The information security behav?ior intention of smartphone users is not only affected by the constructs considered in PMT,but also by other factors such as descriptive norms.%文章以保护动机理论为基础,引入感知威胁和描述性规范变量,构建了研究智能手机用户信息安全行为的概念模型,并通过调查问卷和结构方程模型验证.结果表明:感知威胁、反应效能和自我效能是显著影响信息安全行为意向的重要因素,反应成本的影响不显著;感知威胁在信息安全行为意向和感知易感性、严重性之间起到中介作用;智能手机用户信息安全行为意向不仅取决于保护动机理论模型所囊括的变量,同时也受诸如描述性规范等其他变量的影响.
