现代传媒是社会结构大系统中不可或缺的一个功能子系统,一个重要的社会组织。传媒所具有的社会组织性决定了传媒功能结构的多样化、复杂性。传媒功能是一个结构系统,传媒自身也应该是一个多元复合的结构系统。尽管传媒普遍被视为一种公共事业,但传媒公共性的缺失与公共传媒的缺位,却是世界范围内传媒发展所面临的共同问题。令人担忧的是这种缺失性的结构无疑会导致社会公众利益的损伤。一个较为理想的传媒结构系统应包含三种不同类型并存的媒介形态:国家媒介、公共媒介、商业媒介。文化体制改革关于公益性传媒经营性传媒两分开的目标达成,应该体现为国家、传媒、公众三者利益的兼顾与公平。 Modern media is an indispensable subsystem of a large social structure system and an important social organization. The social organization possessed by the media determines the diversification and complexity of the functional structure of the media. The media function is a structural system, and the media itself should also be a multi-complex structural system. Although the media is generally regarded as a public utility, the lack of publicity in the media and the absence of public media are common problems facing the development of media in the world. What is worrying is that this lack of structure will undoubtedly lead to the damage of public interests. A better media structure system should include three different types of coexistence of media: national media, public media, commercial media. The goal of separating cultural media reform from public management media should be reflected in the consideration and fairness of the interests of the state, the media and the public.
