| “Sharing” is one of the core cultures of the Internet Society.As the main force of social media,young people often share different contents and play different personas on different social platforms.The central question is: How young people share content on multiple social media platforms? The "Sharing" in this article focuses on the status updates that occur on social platforms,that is,what young people post on those platforms.The study collected data through semi-structured in-depth interview and questionnaire survey,using“Structuration Theory” as the basic framework,using the medium-level concepts and microcosmic theories such as “Media duality” and “Adaptive IT use”,this paper responds to this problem from three aspects: “Basic picture”,“Influence factor”and“Using strategy”.The “Basic Picture” aims to describe the way young people use the “social media repertoire”.According to the content shared,the user’s “social media repertoire” is divided into two types: “differential combination” and “connected combination”;according to the frequency of content sharing,the user’s “ocial media portfolio” is divided into(1)We Chat Moments-Weibo centralized sharing(2)intermediate frequency comprehensive sharing(3)short video sharing(4)multiple comprehensive sharing.In addition,social media has been embedded into the daily lives of young people,and the gap between media and life is disappearing.The study found that users can’t help but use real world physical scenarios to describe the experience social media brings them.The discussion around “influencing factors” is based on the “Duality of Media Theory”,using a combination of qualitative and quantitative research methods to explore this issue from “structural factors” and “individual factors”.First of all,the four types of social media repertoires are used as dependent variables to analyze the factors that influence the formation of media combination,the data show that “Time”,“Education” and “Habit” play a key role in the formation of the combination.Secondly,the research returns to the theoretical level,breaks down the "Structural factors" into two dimensions of “Rules” and “Resources”,and further discusses the “Individual factors”from the perspective of “Demand”,on this basis,based on the analysis of the interview data,this paper makes a concrete response to how to understand the “Rules”,“Resources” and “Needs” in media selection,and then constructs an integration model that affects the composition of users’ social media repertoire.Guided by the theory of “Adaptive information technology use”,this paper focuses on the “Configuration strategy”,and analyzes the user’s configuration strategy on the combination of social media from two dimensions of “Relationship” and “Content”,the study found that users are “Redefining” their use of social media,and producers and users are writing social media rules together.At the end of the study,the author returns to the media production end,in order to bring enlightenment to media production through the analysis of user’s media consumption behavior. |
