In recent years，the new generation of information technology has accelerated integration and innovation. The metaverse，characterized by the fusion of virtual and real，has become a hot spot for development，but the insufficient heterogeneous data processing capabilities，urgent need of enrich digital content，as well as high costs of content production needs to be addressed urgently. AIGC（AI-Generated Content） could reduce the threshold of production and consumption of digital content，and support the diversification and customization of digital content in the metaverse. AIGC could also empower the innovation and upgrading of application scenarios such as intelligent manufacturing，municipal services，cultural entertainment，and new consumption. Therefore，China should improve algorithm computing power and data review capabilities，upgrade copyright protection mechanisms and forensic identification technologies，enhance the cultivation of domestic and overseas talents，to promote the prosperity and development of the metaverse digital space.
