A coordination model in co-provision of public service

这一研究项目的目的是阐明各种组织在实施社会基础设施时的集体行动的协调机制，这些组织相互协作，被称为“新公众”。为此，我一直在研究三个问题。首先，研究表明，需要将公平语义作为合作的一种规则来考虑社会资本发展的微观和宏观公众辩论的方式，以获得元协议。第二，构建了区域认同形成模型，对社区合作生产力的可行性进行了评价，并揭示了社区合作生产力可行性的机制。此外，为了定量评价许可引入方式对社会经济系统的协同效应，引入空间托比特模型，构建了志愿公共服务生产支付意愿程度的估计模型。第三项研究采用基于语料库语言学的计算方法，试图通过使用日本东部大地震推特上的危机沟通数据来澄清灾害风险信息共享的现状，并通过对话构建行动调整模型。

The aims of this research project is to elucidate the coordination mechanism of collective actions in implementing social infrastructure by various organizations who collaborate each other, named “new public.” I have been working on three issues for that. First study showed the need for "fairness semantic" as cooperative one rule to consider the way of micro-and macro-public debate on social capital development, to obtain a meta-agreement. Second study has built a regional identity formation model to evaluate the cooperating productivity feasibility in the community and revealed the mechanism. Further, in order to quantitatively evaluate the effect of introduction of permissions manner cooperating on social and economic systems, I constructed a model for estimating the degree of willingness to pay for voluntary public service production by introducing Spatial Tobit model. Third study has adopted a computational approach based on corpus linguistics and tried to clarify the current state of information sharing for disaster risk by using a crisis communication data on Twitter for the Great East Japan Earthquake March 11, and to build the action adjustment model through dialogue.
