虚拟数字人是典型的AI技术集成体，在明晰虚拟数字人技术专利范围的基础上，从德温特数据库获取42556项专利，以此为基础分析了1973年-2020年虚拟数字人技术演变过程，全球领先企业的竞争态势，中美日韩四个国家在虚拟数字人细分技术领域的技术布局，我国虚拟数字人技术发展和相关政策之间的影响关系。最后提出了构建我国虚拟数字人全球竞争力的策略建议，为我国AI技术全球竞争态势的研究提供了可借鉴的方法体系。

Artificial intelligence (AI) has become the core driving force of the new round of scientific and technological revolution. It is of great significance to clarify the international competition situation of AI technology for China to formulate policies in the field of AI and promote AI technology innovation. Metahuman is a typical AI technology integration. On the basis of clarifying the scope of Metahuman technology patents, 42556 patents were obtained from the Derwent database. Based on this, the evolution of Metahuman technology from 1973 to 2020, the competitive situation of the world’s leading enterprises, the technological layout of four countries in the field of Metahuman segmentation technology, China’s Metahuman technology development and the impact of relevant policies were analyzed. This paper puts forward some strategic suggestions on building the global competitiveness of Metahuman in China, and provides a reference method system for the study of the global competition situation of AI technology in China.
