A EXPERIMANTAL STUDY ON HOW TO EVALUATE SOCIAL CONSENSUS FOR PLANS TO RESOLVE SOME LOCAL PROBLEMS

要实施解决地方社会问题的方案，就必须使解决方案与全球性问题形成社会共识。本研究旨在从社会决策过程的角度，提出一个评估社会共识过程的框架。在第一年（1995年），我们已经意识到社会正义，特别是在一个由具有不同价值观的人组成的社会中达成共识。具体来说，我们论证了分配正义的一些逻辑，即自我责任模型和平均主义模型。在这些模型中，我们区分了非自愿的部分和自我负责的部分，并认为前一部分应该只在每个人身上平等。在这些理论论证的基础上，我们构建了一个基于超博弈的学习模型来呈现社会决策过程，该模型不是基于贝斯理论，而是基于扩展学习。利用这一学习模型，我们分析了多功能城邦（MEP）项目，该项目旨在与澳大利亚和日本的工业投资合作，开发一个具有“高科技”和“高触感”功能的未来国际城市。他们目前还没有开始研究MFP，我们研究两种误解；一个是基于谣言和可疑的“飞地问题”，另一个是关于澳大利亚新闻机构如何报道日本企业的投资意愿。结果表明，原来的MFP概念过于复杂，项目处理行为者未能建立良好的公共关系，特别是与澳大利亚国内的新机构。

To implement plans for resolution of problems in local societies, it is essential to make social concensus for the resolution plans in contrast with global problems. This study aims to propose a framework to evaluate a process of social consensus in veiw of a social decison process.In the first year (1995) , we had become aware of social justice to make a consensus especially in a society which consists of persons with various values. Concretely, we argue some logics of distributive justice, namely, a model of self-responsiblity and one of egalitarianism. In these models, we make a distinction between involuntary parts and self-responsible ones, and argue that former parts should only be equalized on each person.In parallel with these theoretical arguments, we construct a learning model on a hyper-game to present a process of social decision, not based upon the Bays theory but an extension learning. Using this learning model, we analyze Multi-Function Polis (MEP) project, which was aiming to develop a futuristic international city including both 'high-tech' and 'high-touch' functions in cooperation with Australian and Japanese industrial investment. They are presently not getting start on MFP,and we examine two kinds of misunderstandings ; one is on 'enclave problem' based on rumors and suspicious, another is on how Australian news agencies had reported investment willingness of Japanese companies. The results of suggest that there existed excessive amount of complexity in the original MFP concept, and the project handling actors had failed to build a good public relationship, especially to Australian domestic new agencies.
