Transnationalization of Labor Market and Restructuring in Local Society: International Relocation of Manufacturing Plants and Foreign Workers in Northern Kanto Area.

本研究的目的是分析产业结构调整，特别是制造业向发展中国家转移对日本境内移民劳动力就业的影响，并特别关注空间维度，即日本境内的区域间分工和特定区域的产业集聚。研究分为三个层次：1)去工业化程度与外来居民比例关系的空间分析；2)外国人居住区位与产业活动动态变化分析；3)在茨城县内外国人（即巴西籍日本人）居住和就业密度最高的两个当地社区进行密集的实地工作。利用GIS对日本外来人口的空间分析表明，由于外来人口的特定产品对市场变化和技术创新敏感，他们在东京和名古屋等特定区域的居住倾向于分散和增加，并保留了更多的制造业活动。通过对茨城县的区域分析，我们发现茨城县西部外来人口的分散性特别明显。相当小的当地社区吸引了巴西日本人，这导致农村地区的外国人口密度极高。通过对其中两个小社区的实地调查分析，得出了一组丰富的数据，包括他们的居住变化模式、工作的空间和产业变化，以及他们的职业和个人生活的时间结构。

The objective of this research project is to analyze the effects of industrial restructuring, especially relocation of manufacturing to developing countries, on immigrant labor employed within Japan with special attentions to spatial dimension, i.e. inter-regional division of labor within Japan, and industrial agglomeration in specific regions. The research constitutes of three levels: 1) Spatial analysis of relationship between degree of de-industrialization and proportion of foreign resident; 2) analysis of dynamic change of location of foreign resident and industrial activities; 3) intensive field work in two local communities where foreign population, i.e. Brazilian Japanese, live and are employed in the highest density within Ibaragi prefecture. Spatial analysis of foreign population in Japan by GIS program showed that they tend to decentralize their residence and increase in some particular area, i.e. outer periphery of Tokyo and Nagoya, where more manufacturing activities have been reserved because their particular products are sensitive to market change and technological innovation. Through regional analysis of Ibaragi prefecture, we found the particular decentralization of foreign population in its western part. Quite small local communities attracted Brazilian Japanese, which resulted extremely high density of foreign population in rural area. The fieldwork with survey analysis in two of these small communities produced a rich set of data on their pattern of residential change, spatial and industrial change of their work, and temporal structure of their occupational and personal life.
