Abstract: The good communication effect of county-level converged media center is the premise of “guide the masses and serve the masses”. However, most of the county-level converged media centers are cur-rently under the influence of mainstream media, commercial media and other subjects, and the communication effect is worrying. From the service logic perspective, county-level converged media center should coordinate with the relationship between different subjects, their own clear posi-tioning, be the “complementor” of the superior mainstream media, the “partner” of the business media and Internet companies, the “collaborator” of the local government and public institutions, gradually form the county-level converged media service ecosystem, promote the communication effect with the quality of service, expand the scope of service with the communication effect, and re-alize the comprehensive and in-depth “guide the masses, serve the masses”.
