The COVID-19 pandemic has accelerated the global digitalization process and brought an important opportunity for the wide application of digital technologies in the world. The “metaverse” that emerged in 2021 has further promoted the migration process of human society from physical space to digital space. A more intelligent and ubiquitous digital society is in full swing. Therefore，it is urgent to speed up the digital transformation of social governance. So far，some countries and regions have formulated corresponding policies，taking digital social governance as an important way to shape new competitive advantages. Against the digital society background，digital identity has become the embodiment of people’s survival，interaction and social relations in the digital space，while digital citizens have become the mapping and copy of citizens in the digital world. With digital identity and digital citizens as the fulcrum，social governance innovation can be instigated with the blessing of digital technologies. This paper，based on this，focuses on the construction and governance of trusted digital identity，as well as the practice of digital citizens，to analyze the transformation of governance space and governance mode in digital society，and to explore the path of building a community of digital social governance，so as to provide reference for the digital transformation of social governance.
