エコシステムガバナンス、 収斂と分岐の反転、 選択機構、 価値のボトルネック、 制度比較分析

抄録

政府の関与と産業の体制は,世代を通じて移動通信の標準化を形づくってきた。本稿は,この構造が6G期にどのように変化しつつあるのかを検討する。van de Kaa and Greeven (2017) の枠組みを5カ国・6世代に拡張し,制度的条件・産業構造・企業水準の成果を結ぶ3層モデルを用いた定性的な比較分析を行う。1Gから5Gまでは,制度的条件が分岐する一方で,標準化の場は3GPPへと収斂した。6G期にはこの配置が反転しつつある。制度層は積極的な政府関与の方向へ収斂し(中国の強制型関与は持続),産業層は3GPPの外側を含む複数の技術ガバナンスの場へと多様化している。本稿はこの反転を,選択機構(コンセンサス標準化委員会)の管轄と,AI・半導体・クラウド基盤へと分散しつつある価値のボトルネックの所在との整合性によって説明する。分析から3つの命題を導出する。あわせて,水平的孤立と技術-エコシステム乖離という日本の事例は,制度的遺産が反転への各国の対応を条件づけることを示している。競争優位の基盤は,単一の標準化団体内での地位から,複数の場への参加とレイヤー間の架橋へと移行しつつあると考えられる。
