【摘要】：云计算自提出以来一直都是学术界研究的热点,也是近年来IT领域最大的进步。但云计算作为一种IT创新,用户对其采纳仍然存在一些顾虑。目前针对云计算采纳的问题,已有部分学者对其进行了理论和实证的研究,并取得了一些研究成果。但是,针对云服务模式的采纳研究较少,并且鲜有关于PaaS采纳的研究。不可否认的是,PaaS服务改变了传统的软件和应用开发模式,解耦了运维团队和开发团队,将极大地提高未来软件和应用交付的效率。因此如何促进PaaS的发展以及提高其采纳率和使用效果是云计算采纳中需要解决的重要问题。本研究在现有云计算采纳方面的研究成果基础之上,整合UTAUT模型和感知风险性,从使用者视角分析和探索PaaS采纳的影响因素。同时,本文还探索了感知风险性在云计算环境下的维度。根据概念模型中相关变量,设计了调查问卷,并通过网络问卷收集数据,利用SPSS20.0和SmartPLS2.0对样本数据进行结构方程模型分析,对模型中各变量的作用关系和假设进行了检验。研究指出,云采纳情景下,感知风险性可以分为四个维度：感知安全风险、感知时间风险、感知财务风险、感知绩效风险；绩效期望、付出期望、社会影响和便利条件对使用意愿的都具有正向影响；感知风险对绩效期望和PaaS使用意愿的直接影响不显著。最后,基于模型的分析结果,文章从多角度为PaaS发展提出建议,对完善云计算采纳体系,促进PaaS采纳有着一定的意义。
[Abstract]:Since the introduction of cloud computing has been a hot topic in the academic field, and the progress of IT in recent years. But the largest cloud computing as a IT user innovation, there are still some concerns on the adoption of cloud computing. The adoption of the problem, some scholars have already carried out theoretical research and empirical on it, and some results have been achieved. However, in view of the adoption of cloud service model research on PaaS adoption and few. It is undeniable that the PaaS service has changed the traditional mode of software development and application, the decoupling operation team and the development team, will greatly improve the efficiency of delivery of future software and applications. Therefore, how to promote the development of PaaS and improve the rate of adoption and the use effect is an important problem to be solved in the adoption of cloud computing. In this study, the existing Cloud Computing Adoption based on the research production, integration The UTAUT model and the perceived risk analysis, from the user perspective and explore the impact of PaaS adoption factors. At the same time, this paper also explores the perceived risk dimensions in cloud computing environment. According to the relevant variables in the conceptual model, design the questionnaire, and through the network questionnaire to collect data, analyze the structural equation model of the sample data the use of SPSS20.0 and SmartPLS2.0, the variables in the model between hypotheses are tested. The study pointed out that cloud adoption scenario, perceived risk can be divided into four dimensions: perceived risk, perceived time risk, financial risk, performance risk perception; performance expectancy, effort expectancy, social influence and convenience have positive effect on usage intention; direct influence of perceived risk on the adoption of performance expectations and PaaS was not significant. Finally, the model based on the analysis results, this article from the It is of great significance to improve the adoption system of cloud computing and to promote the adoption of PaaS in the development of PaaS.
