In recent years, the emergence of issues such as the long-term preservation of internet digital memory and the protection of justice in transnational memory narratives has shown the great changes that globalization and digitalization have brought to the way human collective memory is formed, and has also posed challenges to the long-term preservation of human collective memory. Collective memory is the sum of the memories that a group jointly experiences, passes on and constructs, and it is also key to how nations and ethnic groups construct their identity. In the digital age, collective memory is gradually freeing itself from the constraints of physical space and is characterized above all by flow. The concept of "global digital memory" has emerged from the combined effect of globalization and digitalization.

This study aims to clarify the new problems and new scenarios that the theory of "collective memory" faces against the background of globalization and advances in digital technology. It explains the historical origins and contemporary connotations of "global digital memory" and the "global digital memory field", and summarizes their characteristics of transcending time and space, crossing media, and visualization. It seeks to examine the transformation and development of collective memory practices in the digital age, broaden the directions of memory research, and provide a theoretical foundation for research on archival memory in the digital age. The study was funded by the 2022 Key Project of the National Social Science Fund of China, "Research on Theoretical Innovation of Archival Memory in the Digital Age".
