This research studies social dilemma in socio-economic systems from the viewpoint of farsighted stable set and of fuzzy game theory concept. The following are main results.1 Developing relations between stable sets (and consistent sets) and stationary equilibrium points in a bargaining game, I define a new and more appropriate solution concept to social dilemma situations. I verify its effectiveness applying it to several social dilemma cases.2 I study dynamic coalition formation process by the use of stable sets and the Shapley value. In particular I pick up the Hosokawa anti-LDP (Liberal Democratic Party) cabinet formed in 1993. In the static analysis it was already shown that this cabinet was the only stable coalition. Our dynamic analysis newly reveals that in case the LDP has an initiative in negotiation then pro-LDP cabinet can be formed though the Hosokawa cabinet is formed when an anti-LDP has an initiative.3 Analysis of dilemma situations from the viewpoint of fuzzy games gives us a new insight into the problem how to avoid social dilemmas.

本研究以前瞻稳定集与模糊赛局论概念，探讨社会经济系统中的社会困境。以下是主要结果。1发展稳定集（和一致集）和静态平衡点之间的关系，在讨价还价的游戏，我定义了一个新的和更合适的解决方案的概念，社会困境的情况。并将其应用于几个社会困境的案例中，验证了其有效性。2利用稳定集和Shapley值研究了动态联盟形成过程。特别是1993年组建的反自民党的细川内阁。在静态分析中已经表明，这个内阁是唯一稳定的联盟。我们的动态分析新发现，如果自民党在谈判中占据主动，那么亲自民党的内阁可以形成，而反自民党的内阁则形成细川内阁。3从模糊博弈的角度分析两难局面，为我们理解如何避免社会两难问题提供了新的视角。
