Outline
As the core ability of citizens to effectively participate in digital life，digital literacy has become a key indicator of national competitiveness. This paper systematically reviewed representative international and domestic definitions of digital literacy and distilled their underlying theoretical orientations，thereby illuminating the conceptual evolution of digital literacy. It aims to develop a theoretical system and practical mechanism of digital literacy with local characteristics. This study shows that the connotation of digital literacy has shifted from instrumental competence to a comprehensive competence system covering critical thinking and security. Current research shows three major trends，including conceptual expansion，exacerbation of the literacy divide，and the rise of algorithmic and AI literacy. In the future，it is imperative to develop a local digital literacy theoretical system and an education ecosystem involving multi-stakeholder collaboration，thereby responding to the new requirements in digital society.
