General theory and empirical anrlysis of location of firuis condncting intervational and interregrisnal division of labor

我与巴黎索邦大学的Jacques Thisse教授一起，对空间寡头垄断市场中关注价格和位置竞争的零售公司进行了区位分析。本研究将发表在《国际产业组织杂志》第13卷，与我发表在《区域科学与城市经济学》第24卷和第25号工作论文密切相关。接下来，我使用大阪都市圈的评估土地价值数据分析了房地产市场。在实证分析的基础上，将其与空间竞争理论和非线性定价理论联系起来。最后，我与宾夕法尼亚大学的藤田正久（Masahisa Fujita）教授合作，利用大量的区域时间序列数据，对战后日本的区域增长过程进行了实证分析。该研究将发表在《区域科学与城市经济学》第25卷。重点研究了国际和区域间分工与区域经济的关系以及东京单极区域制度。这项研究与大阪大学的Tatsuo Hatta教授的一篇论文有关，我和我的论文发表在《城市经济学杂志》上。

With Professor Jacques Thisse at Universite de Paris I-Sorbonne, I conducted locational analysis of retail firms paying attention to price and location competition in a spatially oligopolistic market. This research will be forthcoming in International Journal of Industrial Organization, Vol.13, and is closely related to my paper appeared in Regional Science and Urban Economics, Vol.24 and Working Paper No.25.Next, I analyzed real estate markets using assessed land value data in Osaka Metropolitan Area. In addition to the empirical analysis, I related it to spatial competition theory and nonlinear pricing theory.Finally, with Professor Masahisa Fujita at University of Pennsylvania, I conducted empirical analysis on regional growth processes in postwar Japan using extensive regional timeseries data. This research will be published in Regional Science and Urban Economics, Vol.25.Major focus is the relationships of international and interregional division of labor with regional economy and Tokyo monopolar regional system. This research is somewhat related to a paper by Professor Tatsuo Hatta at Osaka University and I and my paper appeared in Journal of Urban Economics.
