企业用户云服务技术采纳及感知风险研究

As the emerging IT service model, the Cloud Computing Service has become one of the focus problems of academic research. Taking the enterprise-oriented Cloud Computing Service as subject investigated, focusing on the security and perceived risk issue of greatest concern which has become one of the basic reasons affecting the adoption of Cloud Computing Service, an empirical study on enterprise users’ technology adoption and perceived risk will be carried out...Based on the generalization of underlying and unperceived enterprise users’ demands for Cloud Computing Service, combining the summarization of crucial functional characteristics of Cloud Computing Service, the theoretical matching model of enterprise users’ demands and Cloud Computing Service’s functions will be proposed. And then by means of case study and expert interview, the matching model will be validated to explore the matching relationship between the enterprise users’ demands and the Cloud Computing Service’s functions...The factors of perceived risks and trust will be introduced and integrated to the model of TOE, combining with the technology factors, organization factors and external environment factors, to establish the theoretical model of enterprise-oriented Cloud Computing’s technology adoption. And then the questionnaire will be designed to make a survey on empirical research. By means of statistical analysis such as multiple regression analysis and hierarchical regression analysis on sample data, the model and hypothesis will be evaluated and result of technology adoption influencing factors of Cloud Computing will be obtained...On the basis of refining the perceived risk dimensions of Cloud Computing Service, the theoretical model of Could Computing Service perceived risk will be established. And then the theoretical model will be validated by the use of questionnaire survey and statistical analytical methods and tools to explore the relationship between the influencing factors affecting the perceived risk of Cloud Computing Service and perceived risk dimensions...This study is going to explore the matching relationship between the enterprise users’ demands and the Cloud Computing Service’s functions, the technology adoption influencing factors and perceived risk influencing factors for Cloud Computing’s application, and try to contribute further study on Cloud Computing Service research. This study on Cloud Computing Service would also put forwards some countermeasures and advice to Cloud Computing Service providers, the Cloud Computing Service adopters and also the government.

云服务作为目前最新兴的IT服务模式，已经成为学术界研究的热点。本课题以面向企业用户的云服务为研究对象，立足企业用户最为关注的技术采纳和感知风险问题，展开以下研究：. 归纳企业用户对于云服务的深层需求特性和需求领域，凝炼云服务的关键功能特征和服务模式，构建并验证企业用户需求与云服务功能的匹配模型，明确云服务以何种模式和何种特性满足用户在何领域的何种需求；整合感知风险和信任因素，修正和扩展TOE模型，构建并验证企业用户云服务技术采纳模型，明确影响企业用户云服务采纳的主要因素；提炼企业用户的云服务感知风险维度，构建并验证企业用户的云服务感知风险影响因素模型，明确感知风险影响因素和感知风险维度之间的关系。. 本课题将通过问卷调查、案例研究、专家访谈等方法进行研究，其研究结果将有助于推进和完善云服务相关理论的发展，并对云服务提供商、云服务企业用户以及政府机构提供借鉴意见。

云服务是当前最新兴的互联网服务模式，让企业用户采纳以及更好的使用云服务，对于企业本身、云服务提供商和行业以及国家战略都具有重要意义。.本课题以TOE模型、模块化系统理论、动态能力理论和IT基础设施能力理论为基础，使用文献研究、规范研究和实证研究的方法，沿着“需求匹配及技术选择→基于风险因素的技术采纳→云服务融合及企业价值提升”的思路展开研究。课题的主要内容和结论如下：.（1）企业用户需求与云服务功能的匹配及技术选择研究。以模块化系统理论为基础，提出研究流程模块化、IT可拆解性和安全风险如何影响云服务技术选择行为的理论模型。研究表明，流程模块化和IT可拆解性都对云服务选择的抽象程度有正向影响，安全风险会正向调节以上两个因素对云服务技术选择抽象程度的影响。.（2）基于风险因素的企业云服务技术采纳与扩散研究。基于TOE模型，从技术、组织、环境和风险四个维度出发，提出企业用户云服务采纳模型。研究表明，任务技术适配度、技术组织兼容度以及规范压力都对采纳意愿有正向影响；而风险因素则对采纳意愿有负向影响。.（3）企业业务云服务融合及企业价值提升影响研究。基于动态能力理论，搭建研究企业动态能力和IT柔性如何影响云服务融合的理论模型；基于IT基础设施能力理论，提出研究云服务融合如何影响企业敏捷性和创新绩效的研究模型。研究表明，企业动态能力和IT柔性都对云服务的融合深度和融合广度有正向影响，融合深度对企业创新绩效有正向影响，而融合广度对企业敏捷性有正向影响。.本课题的科学意义在于：.（1）将模块化系统理论引入云服务技术选择行为研究，是对模块化系统理论应用场景的扩展，也是对云服务技术选择研究体系的丰富。.（2）将TOE研究框架拓展到云服务领域，并着重研究了风险因素对采纳意愿的影响，丰富了TOE框架，也完善了云服务技术采纳研究体系。.（3）拓展了动态能力理论的使用范围，丰富了云服务融合的研究成果，也是对IT价值和云服务价值研究的有效补充。
