共享经济模式已经深入到社会生活的各个方面，目前区块链也正处在风口上，并正在逐步应用到共享经济领域，目前对共享经济模式本质的理论研究还比较缺乏。本课题以共享经济模式中最基本的去中心化机制为研究对象，从信息资源管理视角下的信息不对称切入，开展共享经济模式的理论与应用基础研究。首先，在信息和用户两方面分别研究去中心化信息共享以及用户协作与信息不对称之间的相互作用机制；接着，整合信息和用户研究，并且考虑更多的共享经济平台外部因素，研究去中心化共享生态与信息不对称之间的相互作用机制；然后，从正反两方面，分别就共享的风险和激励，研究去中心化共享的风险评估以及激励方案。课题对理解互联网社会中本质运行机制之一的去中心化有重要理论价值，并对提升企业和政府对共享经济的应用和管理有重要的实践价值。

The sharing economy has penetrated into every aspect of social life. As a cutting-edge technology, the blockchain has been applied to the field of sharing economy. Currently, it is still in an absence of theoretical research in the nature of sharing economy mode. This project, on the basis of information asymmetry from the perspective of information resources management, takes the decentralization mechanism in sharing economy as the research object and conducts theoretical and practical research on sharing economy mode. Firstly, studies would be carried out on the centralized information sharing and interaction mechanism between user collaboration and information asymmetry in terms of information as well as patrons. And then, the project would integrate information and user research. With more external factors of the shared economy platform taking into consideration, the interaction mechanism between decentralized sharing ecology and the information asymmetry would be studied. After that, research would be undertaken in the risk assessment and incentive schemes from both the positive and negative sides. The project is of enormous theoretical value for understanding the decentralization - one of the essential operating mechanisms in the era of the Internet. It can also contribute to enterprises and governments applying and managing the sharing economy operations, which is of tremendous practical value.
