企业用户云服务技术选择行为

如何选择最佳云服务方案，是企业决定采纳云服务之后所面临的一个重要决策。为了解决云服务技术选择问题，从业务流程的视角出发，以模块化系统理论为基础，提出一个流程模块化、IT可拆解性及安全风险如何影响云服务技术选择的研究模型。采用问卷调查和计量经济学的普通最小二乘法OLS进行实证分析。研究结果表明:流程模块化和IT可拆解性对云服务技术选择的抽象程度有显著的正向影响，即流程模块化程度IT可拆解性越高的企业，越倾向于选择抽象程度高的云服务，如软件即服务SaaS；而流程模块化程度和IT可拆解性越低的企业，越倾向于选择抽象程度低的云服务，如基础设施即服务IaaS。同时，安全风险会正向调节流程模块化和IT可拆解性对云服务技术选择的抽象程度的影响。

Enterprise-level Users' Cloud Service Technology Selection Behaviors

How to choose the optimal cloud service resolution,is one of the most important decisions that enterprises are facing after they decide to adopt cloud services. To solve the cloud service selection problem,based on modular system theory,a cloud service technology selection behavior model was introduced,which procedure modularity,IT dismantlability and security risks were proposed as three main influencing factors from the perspectives of enterprises'' business process and IT ability. The Questionnaire and OLS(Ordinary Least Square) were applied in this empirical research. The research results showed that procedure modularity and IT dismantlability had significant positive impact on the abstraction degree of cloud service selection. That meant enterprises which had higher procedure modularity and IT dismantlability were more likely to choose high abstraction degree cloud services,such as SaaS(Software as a Service),and enterprises which had lower procedure modularity and IT dismantlability were more likely to choose low abstraction degree cloud services,such as IaaS(Infrastructure as a Service). The results also indicated that security risks could positively moderate the impact of procedure modularity on the abstraction degree of cloud service selection.
