Basic Study on Establishment of Industrial and Economical Database in Chugoku and Shikoku Districts

本研究于1988年至在教育部科学研究助学金的资助下进行了两年，目的是成功地建立数据库，以便与这两个地区九个县的国立大学合作，对中部和四国地区目前的工业和经济状况进行总体分析。在进行本研究的过程中，组织了三个小组：负责农业、工业和服务业相关的各种数据库建设的经济小组，数据库系统开发小组和综合管理小组。在目标区域方面，中部地区选择了津山市和东广岛市，四国地区选择了今原市和丸户市。在建立产业经济学数据库时，由于数据库的使用目的不同，数据库的意义不同，因此在建立产业经济学数据库时，认真注意澄清区域产业结构和区域特征，以确定区域产业发展和土地利用的基本方向。尽管理解区域特征的方法多种多样，但本研究借鉴农业区划方法，通过实际运用主成分分析的方法，构建了能够较好地理解产业结构平衡率的区域分类图。此外，已经尝试利用规则来建立基于知识的系统，以获得各个行业的区域特征。还分析了SETO内海地区的区域特征，并对建立一般区域特征分析数据库的问题进行了讨论。

The present study has been performed for two years, 1988 through 1989, under a grant-in-aid for scientific research of the Ministry of Education, and has aimed at the successful establishment of database with which a general analysis can be made on the current industrial and economical status of Chugoku and Shikoku districts, in corporation with national universities of nine prefectures in these districts. In performing this research, three groups were organized : economics group dealing with construction of various databases concerned with agriculture, industry and service industry, database system development group and general management group. As for the objective regions, Tsuyama City and Higashi-Hiroshima City were chosen in the Chugoku district and Imabari City and Marugame City in the Shikoku district.In establishing databases with respect to industrial economics, careful attention has been paid to clarify regional industrial structures and regional characteristics which become the guideline to determine the basic direction for regional industrial development and land utilization, since the significance of database differs according to its utilization purpose. Though there can be a variety of ways in understanding regional characteristics, the present study, in reference to agricultural region division method, deals with construction of regional classification map with a good understanding of balance ratio of industrial structure by practical use of principal component analysis. Further, an attempt has been made to establish a knowledge-based system utilizing a rule to obtain regional characteristics of respective industry. The analysis of regional characteristics of Seto inland sea region has also been made as well as the discussions on problems in establishing databases for the analysis of general regional characteristics.
