International Public Goods for Peace and Security in the post-Cold War Era : New Challenge to Construct New Order in the Global Society

本研究的目的在于阐明后冷战时代如何构建国际关系新秩序。这个项目值得注意的是它的跨学科性质，包括经济学、政治学、信息学、复杂性科学等，并受到解决现实世界政策问题的迫切性和理论兴趣的推动。在理论部分，对国际公共产品的概念进行了界定，分析了国际公共产品与国际秩序的关系，并对国际公共产品自发提供的机制进行了考察。在案例研究部分，考察了贸易、核武器和安全问题，以及作为维护秩序的核心的国际条约遵守问题，这些研究成果在许多论文、书籍和报告中得到了宣传。在仿真部分，提出了一种单机型仿真模型及其扩展--基于网络的分布并发仿真模型。…更重要的是，每个国家都被建模为一个独立的代理人，在国家内部存在着多个机构，每个机构又根据职能被划分为小型组织。在此基础上，分析了国际秩序的形成过程，主要集中在外交和战争两个方面。通过在模型中嵌入各种变量，如文化和战略模式，试图通过模拟实验来寻找国际订单产生的条件。此外，我们的成果，主要是在模拟方面的成果，在几个美国研究机构展示，并获得了很高的评价。值得注意的是，我们与开发计划署的一组研究人员举行了会议，就今后的合作交流研究兴趣。而且，我们在迄今所做研究的基础上，对更现实的模拟启用政策实验的未来计划，引起了这些机构的极大兴趣，显示了该项目和未来计划中的成就的高标准。较少

The purpose of this research is to clarify how to build new orders in international relations in the post cold war era. This project is noticeable in its interdisciplinary nature, encompassing economics, political science, informatics, complexity sciences, etc., and in being motivated by both imperative to solve policy issues in the real world and theoretical interests. In the theory part, the conceptualization of international public goods, the analysis of its relation to international orders, and the examination of mechanism for spontaneous provisions of the goods have been performed. In the case study part, issues in trade, nuclear weapons, and security, and the problem of the compliance of international treaties, a core of the order preservation, have been examined.These researches were publicized in many papers, books, and reports. In the simulation part, a stand-alone type simulation model and its extension, a network-based distributed-concurrent simulation model were developed. … More Each nation is modeled as an independent agent, and within the nation there exist multiple institutions, each of which, in turn, is divided into small-scale organizations by functions. Based on the models, emergent processes of international orders have been analyzed, focusing mainly on diplomacy and war. By embedding various variables such as culture and strategic patterns into the models, simulation experiments searching for conditions of the generation of international orders have been attempted. Further, our achievements, mainly those in simulations, were presented at several U.S. research institutions and gained high appraisals. It is worth noting that we had meetings with a group of researchers in the UNDP sharing research interests for future collaborations. And, our future plan for more realistic simulations enabling policy experiments, building on the researches performed so far, drew great interests in these institutions, showing high standards of the accomplishments in this project and the future plan.
