摘　　要： 软件即服务SaaS(Software as a Service)具有技术先进和成本低廉的优势,是提高组织IT性能和竞争力的良好解决方案.但是很多企业考虑到可能存在的种种风险而不愿意采纳SaaS,因此风险因素的分析对SaaS采纳决策具有重要影响作用.使用DEMATEL方法,从安全风险(SR)和IT治理风险(GR)两个维度,分别获取各自的原因—结果因素组,构成可视化SR-GR矩阵,对风险因素进行定量分析.研究结果显示,认证和授权及IT管控权等原因因素是企业Saas采纳的关键影响因素.通过计算各因素的综合影响指数,辨识因素间的因果关系和相对重要程度,从而找出影响SaaS采纳的关键因素,为企业SaaS采纳决策提供相关依据. With the advantages of advanced technology and low costs,Software as a Service（SaaS） is regarded as a favorable means to facilitate a modern organization＇s IT performance and competitiveness.However,many organizations may be still unwilling to employ SaaS mostly due to the concern about the subsequent potential risks. Therefore,an analysis of risk factors has been an important part of the SaaS adoption in decision-making. It utilized Decision Making Trial and Evaluation Laboratory（DEMATEL）approach to define security risk and IT governance risk as two distinct affecting issues so that a causeeffect diagram and a visual SR-GR matrix could be developed respectively for a quantitative analysis of risk factors. The results show that the core of matters of SaaS adoption not only lies in its authentication and authorization,but it is also affected by the Right of IT control. By identifying key influential factors and calculating the index of the combined effects of various factors,it provides practical guidance for SaaS adoption and further exploration of the cause and effect relationship among factors.
