中文摘要：

针对数据安全对中小企业云化迁移的影响,以驱动力—压力—状态—影响—响应（driving-pressurestate-impact-response,DPSIR）概念模型为理论框架,建立中小企业云计算数据安全DPSIR模型,分析中小企业云计算数据安全风险的关联效应,采用决策与试验评价实验室（decision making and trial evaluation laboratory,DEMATEL）方法辨识数据安全DPSIR模型的原因因素和结果因素,并分析该模型中原因因素的中心度和原因度,研究表明中小企业云计算数据安全DPSIR模型的原因因素为P和I,结果因素为D、S和R,进一步分析得出：用户对数据不可控、全生命周期安全、安全边界不确定性是P的关键因素,管理风险、法律风险、技术风险是I的关键因素,研究结果为中小企业云计算数据安全管理预警提供了参考。

英文摘要：

In the view of the influence of data security on transferring cloud computing for the small and medium-sized enter- prises, this paper regarded DPSIR concept model as the theoretical framework, established DPSIR model of data security about cloud computing for the small and medium-sized enterprises, analyzed data security risk relevance about cloud computing for the small and medium-sized enterprises, identified the causal factors and resultant factors of data security DPSIR mode by DE- MATEL, analyzed the centrality and reason of the causal factors of the model. The study shows that the causal factors of data security DPSIR model are P and I, the resultant factors of data security DPSIR model are D ,S and R, further analysis shows that the key factors of P are data isn＇ t controlled by user, security is whole lifecycle, security border is uncertain, the key fac- tors of I are management risk, legal risk and technology risk, the results provide reference for data security management about cloud computing for the small and medium-sized enterprises.
