Abstract: As one of the most significant components of the social system, media is of great importance in communication and coordinating social operation. Due to the increasing complex and multivariate social environment, it is dispensable and vital for the mainstream media of all levels to participate in social governance. Taking six APPs of central, provincial and county level for instance, the research analyses the government, Party affairs and livelihood services to explore the construction and status quo of mainstream media, based on the perspective of structural functionalism. The county level new media steps ahead in social service, media of central level still attaches more attention in information content providing, while the provincial level media has yet found a way to take part in social governance.
