Socialization is a typical development trend of archival culture in the new era, especially in the digital age. As a highly specific concept, archival culture is significantly different from archival content culture. The socialization of archival culture has dual connotations. One is that archival culture expands its social orientation, and the other is that archival culture returns to its social origin. The return of archival culture to its social origin is the progressive expansion of archival culture in its social orientation The archival culture reverting to its social origins signifies a progressive expansion in its societal orientation. The socialization of archival culture should be mainly promoted in four aspects：following the fundamental concept of people-oriented, turning the construction of collections to the construction of archival resources, forging a rational and scientific archival institution framework and using archive data to empower the overall layout of society.
