用户对可用的基于区块链的研究数据共享系统的接受度：一项基于扩展TAM的研究
User Acceptance of Usable Blockchain-Based Research Data Sharing System: An Extended TAM Based Study
AI总结：
本研究基于扩展TAM模型，通过用户评估原型，发现感知易用性、可用性、系统质量和愉悦性均显著影响使用基于区块链的研究数据共享系统的意图，但集体效应不显著。
摘要：
区块链技术已发展成为一种有前景的手段，可在包括医疗保健、农业研究、旅游等领域在内的许多领域中转变数据管理模型。在研究社区中，一个可用的基于区块链的系统可以使用户为其研究工作创建所有权和来源证明，在不失去对其控制权和所有权的情况下共享研究数据，为共享提供激励，并让用户完全透明地控制谁在何时、出于何种目的访问其数据。此类基于区块链的系统的初始采用对于服务的持续使用是必要的，但其用户接受行为模型在文献中尚未得到充分研究。在本文中，我们以技术接受模型（TAM）为基础，并扩展外部构念，以揭示感知易用性、感知可用性、系统质量和感知愉悦性如何影响使用基于区块链的系统的意图。我们的研究基于用户对基于区块链的研究数据共享框架原型的评估，使用了经过验证的TAM问卷。我们的结果表明，总体而言，行为模型的所有个体构念均显著影响使用该系统的意图，而它们的集体效应被发现不显著。系统质量和感知愉悦性对感知有用性有较强的影响。然而，感知易用性对感知有用性的影响未得到支持。最后，我们讨论了我们的研究发现的启示。
英文摘要：
Blockchain technology has evolved as a promising means to transform data management models in many domains including healthcare, agricultural research, tourism domains etc. In the research community, a usable blockchain-based system can allow users to create a proof of ownership and provenance of the research work, share research data without losing control and ownership of it, provide incentives for sharing and give users full transparency and control over who access their data, when and for what purpose. The initial adoption of such blockchain-based systems is necessary for continued use of the services, but their user acceptance behavioral model has not been well investigated in the literature. In this paper, we take the Technology Acceptance Model (TAM) as a foundation and extend the external constructs to uncover how the perceived ease of use, perceived usability, quality of the system and perceived enjoyment influence the intention to use the blockchain-based system. We based our study on user evaluation of a prototype of a blockchain-based research data sharing framework using a TAM validated questionnaire. Our results show that, overall, all the individual constructs of the behavior model significantly influence the intention to use the system while their collective effect is found to be insignificant. The quality of the system and the perceived enjoyment have stronger influence on the perceived usefulness. However, the effect of perceived ease of use on the perceived usefulness is not supported. Finally, we discuss the implications of our findings.
