近些年来，我国在人工智能、算法、网络通信、区块链、虚拟现实技术等数字技术领域实现了重大突破，元宇宙也随之迎来了快速发展。元宇宙致力于打造一个与现实世界平行的虚拟世界，通过扩展现实技术来打破现实世界与虚拟世界之间的壁垒，为用户带来可以在现实世界与虚拟世界之间实现无缝对接的沉浸式体验，实现现实世界与虚拟世界的交融互通。元宇宙的发展无疑将进一步便利人们的生活，成为对现实世界的有益补充，但同时我们也应当警惕元宇宙发展所带来的各项法律风险。在元宇宙中，虚拟数字人不仅是用户在元宇宙空间中的数字化身，更是用户探索元宇宙的必备前提。元宇宙更多作为人们在精神层面上的追求，在人们法律意识的日渐增强的当下，人们将更加关注到个人的人格尊严和社会地位的重要性，名誉权将深刻影响元宇宙用户的体验感与参与感，是开展各项元宇宙活动以及实现元宇宙繁荣发展的重要前提。因而如何合理保护元宇宙空间中虚拟主体的名誉权，成为影响元宇宙空间发展的一项重要问题。

目前，我国并未针对元宇宙的发展进行单独立法予以规制，对元宇宙的发展仍持以观望的态度，而元宇宙应用的成熟只是一个时间问题。元宇宙的发展对于我国现有的法律制度、法律研究以及法治理念带来了全新的冲击与挑战。本文以元宇宙中虚拟主体的名誉权为切入点，围绕元宇宙中虚拟主体为何应当具备名誉权以及侵权责任等相关问题进行展开。结合元宇宙的虚拟性，虚拟主体的价值性以及现阶段法律体系下我国虚拟主体法律地位缺失的现状，阐述论证元宇宙空间中虚拟主体存在名誉权的正当性。在此基础之上，探究当虚拟主体名誉权遭受侵犯时，应当对各类侵权主体采用何种侵权归责原则以及如何对侵权主体合理分配侵权责任。应对元宇宙空间中虚拟主体名誉侵权纠纷，不仅要通过政府的监管与引导，限制元宇宙平台方的权力，完善元宇宙空间中虚拟法庭的建设，加强元宇宙行业自律，更需要我们不断完善元宇宙空间的相关法律，提升元宇宙空间参与者的法律意识。通过各方主体共同努力，实现元宇宙和谐有序的发展。

In recent years, China has achieved significant breakthroughs in digital technology fields such as artificial intelligence, algorithms, network communication, blockchain, virtual reality technology, and the meta universe has also ushered in rapid development. Metaverse is committed to creating a virtual world parallel to the real world, breaking the barriers between the real world and the virtual world by expanding reality technology, bringing users an immersive experience that can seamlessly connect between the real world and the virtual world, and achieving the integration and interworking of the real world and the virtual world. The development of the metauniverse will undoubtedly further facilitate people's lives and become a beneficial supplement to the real world, but at the same time, we should also be vigilant against various legal risks brought about by the development of the metauniverse. In the meta universe, virtual digital humans are not only the digital avatars of users in the meta universe space, but also the necessary prerequisite for users to explore the meta universe. The Metaverse is more a spiritual pursuit of people. With the increasing legal awareness of people, people will pay more attention to the importance of personal dignity and social status. The right to reputation will profoundly affect the experience and participation of users of the Metaverse, and is an important prerequisite for carrying out various Metaverse activities and achieving the prosperity and development of the Metaverse. Therefore, how to reasonably protect the reputation rights of virtual entities in the meta cosmic space has become an important issue affecting the development of the meta cosmic space.

At present, China has not implemented a single independent law to regulate the development of the metauniverse, and still holds a wait-and-see attitude towards the development of the metauniverse. However, the maturity of the application of the metauniverse is only a matter of time. The development of the Yuan Universe has brought new impacts and challenges to China's existing legal system, legal research, and the concept of rule of law. This article takes the reputation right of virtual subjects in the metauniverse as the starting point, and focuses on relevant issues such as why virtual subjects in the metauniverse should have the reputation right and tort liability. Combining the virtuality of the metauniverse, the value of virtual subjects, and the current situation of the lack of legal status of virtual subjects in China under the current legal system, this paper expounds and demonstrates the legitimacy of the existence of reputation rights for virtual subjects in the metauniverse. On this basis, explore what principles of tort liability should be adopted for various types of infringement subjects when the reputation rights of virtual subjects are infringed, and how to reasonably allocate the tort liability to the infringement subject. To deal with the reputation infringement disputes of virtual entities in the meta space, it is not only necessary to limit the power of the meta space platform party through government supervision and guidance, improve the construction of virtual courts in the meta space, strengthen the self discipline of the meta space industry, but also necessary for us to continuously improve the relevant laws of the meta space and enhance the legal awareness of the participants in the meta space. Through the joint efforts of all parties, the harmonious and orderly development of the metauniverse can be achieved.
