This project built some new theoretical frameworks and conducted empirical studies of spatial economics including firm heterogeneity and country/region/city heterogeneity. More specifically, we analyzed gains from trade considering capital mobility and disclosed the economic mechanism for countries to change their parallel import policies. We have made substantial progress in analyzing the relationship between agglomeration and trade in intermediate goods. We revealed how regional governments make good policies to develop their regions by attracting good firms. Finally, we examined the optimal capital tax, optimal property tax, and other related policies considering consumer heterogeneity and differences across and within cities.

Grant amount： \4550000 （ Direct Cost: \3500000 、 Indirect Cost： \1050000 ）
This project studied international trade and regional economics from the viewpoint of spatial economics. I considered the following problems. (1) To disclose the inconsistency between the theoretical and empirical results on the home market effects; (2) To show how offshoring pattern changes in the globalizing era; (3) To analyze some policies for resource-based cities to promote their regional economies when the transport costs of resource goods fall; (4) To reformulate the Hotelling problem when the production is costly; (5) To examine the international tax competition based on some nontariff barriers; (6) To compare how the spatial inequalities change when trade costs of products and mobility costs of capital decline. The results are summarized and published as a Japanese book and 7 English papers in international journals.

This research program investigated the upgrading of China's industrial agglomeration using an interdisciplinary approach of spatial economics and area study. The results of our researches can be summarized as follows: 1. We built many spatial economic models including a multi-country or multi-regional model in which the level of wage is endogenously determined with capital movement; 2. We conducted many econometric investigations including an analysis assessing the impacts of new highway constructions over the Chinese regional economy; and 3. an analysis elucidating the mechanism as to the accumulation of soft information in the relational banking by local banks in China's garment industrial clusters; 4. We made unique case studies focusing on the knowledge and information sharing between global platform-vendors and local mobile phone-set manufactures in Pearl river delta region of China so that we clarified the upgrading mechanisms of China's mobile phone-set industry.

In pursuing sustainable regional economies, we cannot avoid uncertain phenomena, such as natural disasters. Based upon the experience of Higashi-Nihon Big earthquake, we estimate regional economic potentials before/after earthquake by expanding the new economic geography model. By calculating and simulating the model we have reached to the conclusion that workers tend to move back to coastal area by economic recoveries.
By implementing the research we constructed regional economic circulation theory and conducted several applications to real regional economies.

This project develops spatial economics and considers policies to realize sustainable growth of urban and regional economics from the following four aspects. 1. We formulate models of spatial economics which can be applied to examine urban and regional policies for economic growth. In particular, we reveal a new mechanism of spatial income inequality which is related to the research of economic inequality and growth theory. 2. We examine policies for sustainable development of cities and regions. We investigate the role of tourism industry, the behavior of city developers and land use. 3. We study transport policies from the viewpoints of industrial agglomeration and disaster prevention. 4. In empirical studies, we examine interregional utility differentials, agglomeration effect of inter-firm backward and forward linkages and decreasing transportation costs by use of firm-level data.

The new field of spatial economics has been developed rapidly since the early 1990s by economists in Japan, U.S. and Europe, aiming for the unified theory of geographical economics. This research has succeeded in the further development of spatial economics towards a comprehensive theory of geographical economics in the age of globalization and brain power society. In particular, we have succeeded, perhaps for the first time in the world, in developing a dynamic micromodel of knowledge creation and transfer, through interactions among heterogeneous knowledge workers in multiple regions.
Water resources in Kagawa Prefecture and fair assignment

We showed the current situations of water resources in Kagawa Prefecture and considered the fare assignment of water resources according to the methods of effective usage. Because Kagawa ditch and Hozan-ko lake were recently completed, the demand-supply relations are greatly improved. On the regional economy in Kagawa Prefecture total regional resources are becoming more important than the lack of water resources. According to these changes we considered the fare assignment of water resources and effects on the industrial location in Kagawa Prefecture theoretically.

We showed analytical framework for understanding regional economic structure in terms of regional money circulation as a basis of regional competition. From theoretical point, cultural differences as well as economic disparities among regions may become obstacle to interregional collaboration. In addition, we focused on regional disparity which is important element for regional collaboration, and develop a new interpretation for expanding regional disparities. In expanding period of regional disparities it is shown that agglomeration economies have an important role in a process of new steady state.

This study contributes to the regional science in two points. The first part is the mathematical study on spatial economics, clarifying the mechanism of industrial agglomeration by a general-equilibrium framework. Particularly, we study the economy in a space of multiple industries and multiple regions, develop the international trade theory, and apply the results to resolve some problems in environment economics and development economics. The results are summarized in 9 academic papers, published (or accepted) in well-known international journals. The second part is the mathematical study on conflict resolution. We examine new arbitration procedures AFOA and DOA proposed by the applicant by use of experiments and show that AFOA works better than other existing procedures. We also extend the graph model for conflict resolution by use of the concept of strategy in dynamic game theory. The results are summarized in 7 academic papers, 6 of them are published in well-known international journals, and one of them is published in a Japanese journal for Japanese lawyers.

Our research focuses on the resolution of conflicts theoretically and practically. The multilateral conflict aspects are considered. Our approaches are based on possibility theory, bidding theory, cooperative game theory and graph models.
Fair cost sharing of network maintenance is analyzed. It is shown that the Shapley values of cooperative game theory give a rational resolution of the problem. We give a definition of characteristic function of network structure then define the Shapled values on it. They can be calculated very easily. The idea is applied to the actual situation, maintenance of railway network by the local governments, and we show that theoretical result is similar to the actual situation.
Applying the graph model to the conflict resolution, we propose a new way of policy analysis. It is shown that the important thing about the refinement is limited to the stakeholders' direct interests.
We also consider the bidding problem of the public construction. It is pointed out that under an uncertainty such as ground condition the expected values are not appropriate for both governments and builders. We propose a new bidding system that does not use the expected values as payoffs. Our bidding system is designed by using the second price bidding system.
We formalize the uncertainty of demand by possibility distribution, then propose a new decision models. By our new decision model we can determine the optimal order quantity of the short life cycle goods.
We have proposed several ways of conflict resolutions that can be applied to the actual situations. It is expected that these will be applied to many real conflicts.

We have published 6 papers and made 4 presentations. The summary of each article is as follows:
(1) We give a new existence result for a general game. Then the result is applied to the symmetric arbitration games FOA and DOA. It is shown that DOA leads to a convergence of offers but FOA does not.
(2) We present a new moving knife procedures for ε-approximate envy-free cake division, whose idea also works well for chores division. The procedure is generalized to multi-fair division. The number of necessary cuts is bounded.
(3) Multi-source possibilistic information is presented by a set of possibilistic constraints to characterize decision variables from different information aspects. Possibilistic linear programming is used to integrate multi-source information into upper and lower possibility distributions of decision vector.
(4) We investigate the conflict situation of experts' knowledge. We present how to resolve such conflict to obtain more reliable and refine knowledge that can be used for decision-making.
(5) An alternating prisoner's dilemma game of linear function moves is considered. We present the existence condition of stable equilibrium points when a player plays a game against the players using the same type of strategies.
(6) A dispute among the local government and residents of two regions is analyzed. We present the resolution of the dispute.
(7) We show that the deficiency of combined arbitration and double-offer arbitration can be corrected by a combination with conventional arbitration.

The main aim of this research is to clarify the regional economy in modern China, which has been rapidly changing by introducing a new system of market economy into the old and traditional planned economy. In order to carry out this kind of research project, we tried to make some comparisons between the Chinese regional economy and the Japanese regional economy in the past. We also put an emphasis of our empirical fact-findings on revealing regional diferentials of, say, between the coastal and inland areas, as well as the urban and rural areas, so as to derive the meaningful and efficient policy-recommendations for the Chinese regional economy. The performance of this research project is summarized by the following paper, entitled the 'Research of Modern Regional Economies in Both China and Japan.' Eventually, this paper is truly a joint-reserach work by the Scholars of Northwest University in Chana and Kagawa University in Japan.It consists of the following three parts : 1) How to Evaluate the Current Situations (Recognition of the Status Quo), 2) Theoretical Research Works (by Regional Ecomonics), 3) Empirical Reseach Works (for Regional Policy).

本年度は,公平分割(ケーキ分割)モデルに重点を置いて、紛争解決の研究を進んできた。このモデルでは、n人(プレーヤー)が一個のケーキを比率〈α_1,…,α_n〉で分割する。各プレーヤーはこのケーキの各部分に関する好みが異なるかもしれない。その好みは個人情報であり、他の人には知られていない。問題は、このケーキをどの手順で分割したら、各人とも自分の好みで満足できるか。ただし、手順には個人情報としての各プレーヤーの好みを利用することはできない。なお、比率〈α_1,…,α_n〉の決定は今まで研究してきた仲裁方法に関係する。
●まずは、今までの公平分割とその手順に関する研究の成果とその問題点もまとめて、論文「公平分割とその手順」を書いて、応用数理学会の学会誌「応用数理」に掲載された。
●次は、現実問題への適用の観点から、近似公平を保証する分割手順の開発を行った。その結果は論文“Approximate envy-free algorithms"として、国際会議Game Pratice Iで発表した。これからその論文を修正して、雑誌か論文集へ投稿する予定である。
●1997年の実績報告書に報告した論文「Mark-choose-cut algorithms for fair and strongly fair division」が1999年に出版された。
●1997年の実績報告書に報告した論文「初等的フローゲームの凸性について」は電子情報通信学会論文誌D-IのJ81-D-I,No.6に掲載された。
なお、地域間の紛争を解決するため、全国の租税政策により地域人口の移動を分析した。その結果は論文「投資家と住民の移動モデル」として日本経済学会で発表した。これからその論文を修正して、雑誌へ投稿する予定である。
