Against the background that digital technologies have fully penetrated all sectors of the economy and society, the digital economy has become the core engine driving urban-rural integrated development. As a key link connecting higher education resources and regional development needs, new-type undergraduate universities are playing an increasingly prominent role and value in serving urban-rural integration. Based on the internal logical connection between the digital economy and urban-rural integration, combined with the school-running orientation of new-type undergraduate universities, application-oriented, industry-oriented and local-oriented, this paper analyzes the opportunities and challenges brought by the digital economy to urban-rural integration, discusses the core advantages and practical dilemmas of new-type undergraduate universities in serving the flow of urban-rural factors, industrial upgrading and equalization of public services, and finally constructs a practical path for new-type undergraduate universities to serve urban-rural integration from four dimensions: talent training, scientific research innovation, social services and governance collaboration. It provides theoretical references and practical experience for promoting high-quality integrated development of urban and rural areas.
