Outline of Research at the Start

情報化・ネットワーク化の進んだ現代社会において,社会ネットワークがどのように動的に変化しているのかを理解し,効果的に運営・管理することは極めて重要な課題である.既存研究ではしばしば社会の構成要素が同質であると仮定され,実社会が持つ個の多様性は積極的に考慮されてこなかった.本研究では「適応的ネットワーク」という独自の枠組みを用い,個の性質に多様性を導入した数理モデルを構築する.モデルのパラメータ値は実社会ネットワーク時系列データの解析から推定する.以上を用いた大規模計算実験により個の多様性と社会構造との関連を明らかにし,従来理論では予言されなかった「多様性と接続性が共存する社会」の可能性を探る.

Outline of Final Research Achievements

This study examined how the diversity of individuals constituting a society affects the social structure and its changes. Specifically, using the framework of "adaptive networks," we constructed several simulation models in which diversity was introduced into the characteristics of each individual, and investigated their properties through systematic computational experiments. In addition, we quantified the actual behavior of individuals and their diversity in society by analyzing real-world network time series data and social experiment data, and compared them with the findings obtained from the computational models. As a result, it was suggested that the diversity of individual behaviors could help achieve a "diverse yet connected" society, which was not predicted by existing theoretical models.

Academic Significance and Societal Importance of the Research Achievements

スマートフォンやSNS等,個人レベルでの情報収集・拡散技術の発展により,社会構造の変化は加速し,同時に意見相違や地位格差の拡大のような不安定性も生じ始めた.こうした急速な情報化・ネットワーク化の進行は,マクロレベルで個々人の意図を超えた予想外の社会ダイナミクスを産み出しており,社会ネットワークの動的変化の理解・予測・管理は学術的・応用的に極めて重要な課題となっている.以上の背景のもと,本研究は,個の多様性が社会の動的変化に及ぼす影響を明らかにし,また多様な個の状態を維持しつつ社会の接続性も確保するにはどうすべきかという重要な問題について示唆を与えるもので,その学術的・社会的意義は大きい.
