信息不对称视角下数据安全对中小企业云计算采纳影响的动态博弈

Dynamic game of cloud computing adoption for the small and medium-sized enterprises under the influence of data security from the perspective of information asymmetry

云计算为广大中小企业的信息化带来优势的同时也带来数据安全威胁,中小企业和云服务提供商在云计算数据安全领域存在典型的信息不对称现象。提出数据安全影响中小企业云计算采纳的不完全信息动态博弈模型,通过多阶段博弈来分析数据安全对中小企业云计算采纳的影响,分析博弈模型均衡下中小企业和云服务提供商的策略组合,并给出减少中小企业云计算数据安全信息不对称的补偿估算过程。研究表明,通过市场补偿,中小企业和云服务提供商都致力于减少云计算数据安全的信息不对称,从而降低数据安全对中小企业采纳云计算的影响。

Cloud computing brings not only advantages, but also data security threats for the informatization of the small and medi- um-sized enterprises. Typical information asymmetry consists in the data security information of cloud computing between small and medium-sized enterprises and cloud service providers, presents a dynamic game with incomplete information model of cloud computing adoption of the small and medium-sized enterprises produced by data security, analyzes the effect on cloud computing adoption strategies of small and medium-sized enterprises given rise to by data security through the multi stage game, probes into the strategy combination under game equilibrium between the small and medium-sized enterprises and cloud service providers, gives the estimating process of compensation about removing cloud computing data security information asymmetry. In order to cut down the influence which is led to by data security toward cloud computing adoption of the small and medium-sized enterprises and lessen information asymmetry of data security with regard to cloud computing market for the small and medium-sized enterpri- ses, the study states small and medium-sized enterprises and cloud service providers focus on reducing the information asymmetry about cloud computing data security through the market compensation, this helps to reduce the influence caused by data security for the small and medium-sized enterprises adopting cloud computing.
