地域経済構造とBasic Industry “Basic Industry for Regional Economic Development”

抄録

There is a widespread opinion among regional planners and research workers that the crude theory of economic base serve as a short-cut in analysing the structure and in assessing the developmental possibilities of a region. By making the assumption that the so-called basic-nonbasic ratio is a constant, this theory usually carries a central notion of one-way relationships; a change in the basic industries causes a change in the nonbasic industries.
A region, however, may very well continue to grow, even if its basic industries do not expand. There is really no conceivable reason why those industries which produce for the expart market are referred to basic and all other industries which produce for the local market are referred to nonbasic, and also why only the former are claimed to constitute the foundation of the region's economic growth.
As we know, the Moses' model of interregional input-output is far more comprehensive to understand how the regional economy functions; this model which hopeful will improve the rough idea of base approach by a process of flow disaggregation. This might be of some interesting problem in this field. In this paper, we try to move in small steps for measuring the basicness of an industry to a region. That is, our point is to measure not only the degree to which the industry itself is a basic industry but the degree to which the industry is vital to the region, in other words the greater degree of direct and indirect effects from the both side of interindustry and interregional trading structure.
It is our hope that our framework and findings in case study used the data of commodity flow may help to throw some light on the developmental possibility of the regional economy.
