| Nowadays,social short videos have gradually approached the social media status of We Chat,and have become the main social position for young people.Teenagers take fun and social interaction as a link,and through the creative expression and interactive communication of short videos,they can open "weak ties" and maintain "strong ties".The complex and close social network is the fertile soil for nurturing social capital.However,adolescent social capital is constructed and dissipated in self-presentation.Whether the self-presentation of current adolescents can substantially enhance social capital needs to be explored.This paper aims to ensure the effectiveness of the construction of social capital for adolescents,and deeply restores the status quo of the self-presentation and social capital construction of adolescent groups in social short videos.Evaluate.This paper adopts a combination of qualitative and quantitative methods to randomly distribute questionnaires among young people aged 14-25 in the Yangtze River Delta region to investigate the interaction behavior and social capital in social short videos.Finally,427 valid questionnaires are quantitatively analyzed.And it is concluded that teenagers accumulate their personal network capital,emotional capital,knowledge capital and trust capital through four paths of socializing,seeking identity,learning skills and deep trust,so as to exert the positive function of individual social capital.However,due to the conservative social methods of young people on the platform,their social capital has increased in quantity,but there has been no qualitative change.To a certain extent,the conservative social core of teenagers even reverses the disintegration of individual social capital,making them ineffectively constructing virtual social capital,but also have no time to take into account the accumulation of real social capital,thus falling into the quagmire of “the more social the loneliness”.Difficult to escape.In this regard,this paper proposes to establish a "four-dimensional integration" youth social capital security system.On the one hand,the social capital of young users is escorted from the four dimensions of government,platform,school and family.On the other hand,the main body’s self-salvation consciousness is brought into play,and social short videos are used to realize the transformation of virtual and reality,and online and offline social capital.Guide young people to socialize positively in the era of social short videos,and give full play to the positive function of social capital.This study expands the research path directed by the results of self-presentation,and evaluates the self-presentation of adolescents in social short videos from the perspective of social capital.The theories and models of social capital construction in the field of economics are innovatively applied to the study of adolescents’ social behavior,so that we can think about the construction of adolescents’ social capital on social media from a new perspective.On the other hand,this paper analyzes and makes suggestions on the current situation of teenagers getting lost in social short videos,so as to guide teenagers to redeem themselves in the confusion of cyberspace,avoid the risk of accessing the Internet at a young age,and better implement the network protection of the "Minors Protection Law". |
