The purpose of this paper is to build the computer-simulation model of household location. The model consists of these four components: (1) household types by occupation, family income, savings, etc. (2) location categories, (3) preference-lists of location categories by each household type, (4) search procosses of household locations. After building the computer-simulation model, we have applied to forecast the future putterns of the Nagoya Metropolitan Area and to estimate the effect of public actions, such as zoning, code-enforcement, public housing supply etc.

This paper concerns the following problem: in the usual interregional input-output analysis, the inverse matrix only shows the ultimate total effects of interregional propagation, but we cannot draw any information on the partial interactions between two or three regions which night be thought to have structurally different characters. How, then, is it best taken into account?
This paper can be divided into two parts. In the first part, we consider the theoretical framework to clarify the problem of this type. There, we formulate the “general model partitioned into three regions”, with meaningful notions.
In the second part, we apply our formula to the Interregional Input-Output Model of the Japanese Economy. Some empirical findings of this study are summarised there.

The estimation of the economic benefits of a public investment project should include not only the direct effects but also the indirect ones. The problem is seen even more clearly when considering projects involve investments for increasing assets in social overhead capital, such as roads, railways, ports, etc. These projects often show a direct benefits only, which may be less than unity if the services produced are not sold, but consideration of the benefits deriving from the execution of such projects often shows that they are of top priority. In these cases the most important benefits are indirect, since they make production possible in other sectors of the economy.
In this drafting, we deal with an estimation of direct and indirect economic benefits to a region which derived from the public investment for port facilities, by preparing a simplified system as shown in Fig. 1.
Thereupon, such economic benefits are defined as an increment of the net regional products. Then the econometric model and interregional input-output model are introduced to analyze each process of this system mentioned above.

Dominant economic growth in Japan produces structural changes in backward area. Under structural changes, backward area in Japan divides into three groups; Backward-Growing Area, Backward-Stagnant Area and Backward-Mature Area.
This paper analysis developmental turn-point in Backward-Mature Area in relation to transport alternative.
Developmental strength in backward area is specialization of industry. Developmental turn-point in Backward-Mature Area is attributed to diversification of industry. The structural changes introduce this diversification into Backward-Mature Area, and transport alternative, as catalytic effect, contributes to this diversification. This is the reason of developmental turn-point in Backward-Mature Area.

There are two ways for forecasting of travel Demands. The one puts a commodity flow, and the other does an automobile flow of today.
In this paper, we take the first one, because we should like to have both travel demands of railroads and highways in 1970.
We build many mathematical models of travel demands with some Origin-and-Destination studies, and estimate the demands with applying them by zone, by each kind of commodity.
