既存事業者とプラットフォーム事業者の関係の変化

―コンテンツ産業における補完と競合の併存構造―

抄録

The advancement of digitalization is replacing existing analog businesses with digital models across various industries. In the content industry, which provides videos, music, manga, books, magazines, newspapers, and other media, this transition to digital models is also occurring and has entered its second round. 'Second round' refers to a secondary shift that further replaces the initial digital model transformation of analog businesses. As digitalization progresses, entrants such as platformers appear within the industry, creating a contradictory relationship of 'complementarity' and 'competition' with the incumbents. However, this contradictory relationship existed before the emergence of platformers. This study examines where the relationship of complementarity and competition arises in each round of digitalization, using case studies from the newspaper and music businesses. It shows that as the rounds of digitalization advance, the relationship between incumbents and platformers is changing, and at some point, complementarity and competition will coexist.
