在冷战结束后开启的传播全球化背景下，作为媒介学的核心概念，媒介域对媒介技 术发展阶段的历史性区分从新的方面界定了历史视野中的媒介制度和社会现实的对位关 系。市场建构的社会理性催生了传播学，结合技术主义和历史主义的复合价值观，在方 法论探讨的意义上，本文认为媒介域可以帮助我们理解新信息文本与已有制度管控的竞 争型互动关系、信息算法的指数风险和技术挪用主导意义的阐释。同时，媒介域也在技 术效应的复制放大中改变了人们对社会关系和社会环境的思维方式。

Under the background of communication globalization, which opened after the end of the Cold War, mediaspheres is the core conception of media science. The historical differentiation of media technology in the development stage of mediaspheres in a new aspect defines the counterpoint relationship between the media system and social reality. The market constructed social rationality has given birth to communication science. Combines the values of technologism and historicism, in the sense of methodology, this paper argues that mediaspheres can help us understand the competitive interaction between the new information text and the existing system, help us understand the exponential risk of information algorithms and the interpretation of the dominant meaning of technology misappropriation. At the same time, in the process of reproducing and amplifying technical effects, mediaspheres also change the ways of thinking about social relations and social environment.
