Under the social background of the gradual penetration of the platform into the people’s daily life, the platform can no longer be simply understood as a medium and more people carry out daily life practice based on the media logic formulated by platform capital, and generate a new “platform institutionalized mode” which users actively take the platform media logic as the reference frame to extend the media culture production carried out in the platform space into the daily life practice. User practice increasingly relies on and adapts to the platform system, and finally generates a platformcentered, stylized, predictable and standardized practice mode. The “platform institutionalized practice” makes the social structure present a trend of restructure, including the restructure after the reconstruction of the spacetime structure, the reconstruction of the public’s daily life style, and the formation of new social exchanges, social order and social power structure. Finally, the “platform institutionalized practice” builds a “programmable” new form of digital society.
