In recent years, with the rapid development of next-generation digital technologies, the vigorous growth of the digital economy, and the continuous deepening of the strategy to build a strong education nation, the digital transformation of vocational education has increasingly become a focal point. This trend has prompted researchers to delve into the background of digital transformation in vocational education, the current challenges and difficulties it faces, and actively seek effective pathways to enhance vocational education quality through digital transformation. It also explores how to better leverage the potential of digital technologies in educational services. Against this backdrop, this paper employs CiteSpace software to conduct a visual analysis of research literature related to digital transformation and vocational education, aiming to outline the research hotspots and evolutionary trends in this field. Based on the analysis results, the paper further proposes constructive suggestions and prospects for the future development direction of vocational education digital transformation.
