所有とアクセスからみた情報メディアの利用

Purpose: Information behavior has changed in recent years following the increase in economic activities based on access. Five types of information media use were categorized based on a previous study of ownership: ownership, quasi-ownership, and access types 1, 2, and 3. To clarify the current trends in media use, we conducted a survey of the current uses of four types of media: novels, nonfiction books, comics, and music. The respondents were categorized based on their information media use. Methods: An online panel survey was conducted in Japan with 1,030 participants who were counterbalanced by gender and age. The questions consist of 30 items related to media use, 5 related to physical media orientation, 3 related to frequency of media use, 2 related to possession and use of computer devices, and 10 related to personality. Results: Of the 30 questions on media use, more than half of the respondents answered "never/ don't know/no idea" to 27 questions. However, 41.9% of the respondents answered that they "very often/often" listen to music on free online video-sharing platforms such as YouTube. Seven clusters were identified based on hierarchical clustering from the answers for media use. The five clusters that indicated less use of information media were: "only YouTube," "nonuser," "library user," "music subscription user," and "ownership." The two respondent clusters that used information media frequently were: "active user of all media" and "active user (mainly access type 3)." The characteristics of the clusters were discussed.
