In the information-overloaded digital age

Archive culture is evolving from an elitist act of historical preservation to a "digital archaeology" practice deeply empowered by social media and widely participated by Generation Z. This study takes the spread of Archive culture among Generation Z as an entry point

aiming to explore the internal logic of how social media empowers subculture dissemination. By constructing a triple empowerment model of "technical architecture - cultural symbols - social relations"

this paper reveals how social media platforms transform niche nostalgic behaviors into a collective ritual and identity construction movement through visibility production

meaning reconstruction and community connection. The study found that the communication process forms a complex network of actors consisting of cultural curators

platforms

brands and users

and presents a diverse appearance in the context of global localization. The core takeaway is that the key to the successful dissemination of contemporary subcultures lies in providing "portable identity tags"

creating "unfinished texts" and building "virtual and real interwoven experience loops". This study provides a theoretical reference and practical paradigm for understanding the picture of subculture communication in the digital age

as well as for in-depth cultural dialogue between brands and youth groups.
