大学生のソーシャルメディア利用の規定要因：Twitter，Instagram，TikTokに着目して

抄録

    In this paper, we would like to examine the purpose of social media use among university students in Japan to discuss the everyday world we live in while utilizing social media. We analyze quantitative data from the 2020 nationwide survey of ’Lifestyle and Attitudes of Japanese university students’ by Japan Youth Study Group.

    In our survey data, we found that most students used multiple social media networking services simultaneously, rather than just one of the platforms. Forty percent of the students used Twitter and Instagram simultaneously, followed by 18.4% using Twitter, Instagram, and TikTok; 9.7% using Twitter, Instagram, and Facebook; 9.3％ using Twitter only; 7.8% using Instagram only; and 0.2％ using TikTok only. Very few of the students used only one type of social media platform (There are no Facebook only users).

    As a result of the analysis, it was found that simultaneous users of TikTok along with Twitter and Instagram, but not Twitter or Instagram users alone or simultaneous Twitter and Instagram users, have multiple hobbies such as idols and fashion, as well as multiple forms of human relationships including ’face-to-face relationships’ and ’media-mediated relationships’. It is conceivable that students utilize multiple social media platforms accordingly depending on their hobbies and human relationships.
