Outline of Final Research Achievements	Pricing in sharing services is believed to become a significant issue in the future. In this study, we assumed this pricing problem as "How should we reflect the inefficiencies experienced by each user due to collaborative usage in the pricing while maintaining social acceptability and sustainability in cooperative sharing?" We attempted to analyze, examine, and construct pricing methods through (A) a mechanism design approach, (B) a transportation planning approach, and (C) a multi-agent learning approach. As a result, we were able to demonstrate the effectiveness of introducing declaration of willingness of use by passengers, propose dispatch allocation algorithms for improving fairness among drivers, confirm the importance of multiple options in the transport service design of subscriptions, and indicate the potential for designing a pricing system through evolution and elimination process by GA in social simulation.

Academic Significance and Societal Importance of the Research Achievements	SGDsのための社会設計としてのシェアリングサービス設計は今後重要となり、その中でも利益配分やコスト負担のバランスは社会制度の持続性に大きく関わる。本研究成果はまだ基礎的な知見ではあるものの、工学的視点でバランスの取れる方法を提案することができたといえる。また、ゲーム理論あるいは計算社会科学的な視点でも、効率性と公平性のバランス問題や進化的な価格設定と利用者選択モデルの関係など、新規性のある手法や知見が得られたと思われる。
