With the widespread penetration of digital technology, the digital economy has become a vital engine for advancing rural revitalization. The development of the new media digital economy industry by local governments demonstrates significant empowerment effects on rural revitalization, yet its complex mechanisms and implementation pathways require further exploration. Drawing on the practical experience of Rongjiang County in developing the new media digital economy industry, this study further refines the internal mechanism through which this industry empowers rural revitalization. This mechanism includes: enhancing farmers ’ technical skills through training, empowering industrial development with precision via data innovation and application, amplifying resource endowment advantages through online promotion and traffic generation, and promoting employment and income growth through live-streaming commerce. This study provides a theoretical framework for explaining the relationship between the new media digital economy industry and rural revitalization. Based on this, this paper proposes measures to promote the development of the new media digital economy industry: improving organizational support mechanisms, cultivating and attracting high-quality market entities, establishing talent training systems, and innovating live-streaming commerce models. These measures aim to further empower comprehensive rural revitalization.
