Social Media and Cultural Knowledge Empirical Study in Digital Era

Abstract

In the digital era, social media is key to cultural knowledge transmission, influencing public cognition, cultural identity, and cross-cultural interaction. Previous studies focused on theory, lacking systematic empirical research on social media's operation and effectiveness in cultural knowledge dissemination. This study uses mixed methods (content analysis + user surveys) on mainstream platforms to explore their dual roles in promoting local and intercultural knowledge exchange. Findings show that algorithms, user engagement, and content adaptation affect knowledge reception and dissemination. Platforms reproduce local knowledge, and user re-creations reflect hybrid culture, highlighting user participation in identity construction. This paper bridges theory-practice gaps, offering empirical support and strategies for digital cultural knowledge management, governance, and platform regulation.
