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，对零售企业进行了区位分析，关注空间寡头市场中的价格和区位竞争。本研究将发表在《国际产业组织杂志》第13卷上，与发表在《地域科学与城市经济学》第24卷和第25号工作论文上的论文密切相关。接下来，利用大坂都市圈的地价评估数据，对真实的房地产市场进行了分析。最后，与宾夕法尼亚大学的藤田正久教授合作，使用大量的地区时间序列数据，对战后日本的地区增长过程进行了实证分析。本研究将发表在《地域科学与城市经济学》第25卷。主要研究国际和地区间分工与地域经济和东京单极地域体系的关系。这项研究与大坂大学教授八田达雄和我发表在《城市经济学杂志》上的论文有一定的联系。

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.
