About distribution of traffic volume on a road network system, we have today accumulated every OD traffics in every arcs of network, considering with minimum traffic times, distances and other criterions. In this method, the OD traffics are grammatical subject and the network is object. The OD traffics have been able to chose their own pathes by their self, among many roads of the network system. Now in this paper, we shall study a contrary method of traffic distribution, namely the network system i s subject and OD traffics are object. Here, urban road network is a “Machine” and cars are “Materials”, and also the “Machine” is a “Markovian Machine”. This method will be usefull to urban “dence” network, and short-run prediction.
In a usual simulation analysis of a regional economy, only region-wise interaction mechanism built in a model is that of between a regional and national economy. On the contrary, our econometric model tries to clarify the multiple region-wise interaction mechanism between (1) the regional and the national economy, (2) the regional and other influential regional economy, (3) sub-regional economies included in the whole region. As a numerical example, the econometric model of ‘Chuyo Region’ - the region surrounding the City of Nagoya - is shown. The whole equation system consists of four sub-sets of simultaneous equations. The analysis is performed by comparing the following various elasticities calculated from coefficients obtained by equations in reduced form, ∂Oi/∂Oj•Oj/Oi, ∂Yi/∂Oj•Oj/Yi, ∂Oi/∂GjGj/Oi, where O means the output of the manufacturing industry in the region or sub-region, Y the income of the regional or sub-regional economy, G the national or regional or sub-regional government's expenditure, and the suffix i or j means ith or jth region or sub-region or the nation.
The Paper presents an econometric model of the Osaka Prefectural Economy consisting of equations and by extrapolating the exogenous variables, predicts the future of the Osaka Economy. The model differs from the ordinary national income three sectors model in that it incorporates, in it the equations of domestic migration and the demands from the rest of the Japanese Economy.
Recent economic growth has accompanied with bottlenecks of related facilities. We have to research the trend of industrial location for planning public investment. (1) Trend of industrial location is changing, been accompanied with change of industrial structure. Oil and machine industry are now accomplishing the highest rate of growth, and these types of industries are located neighbour of the great industrial region. (2) Classificated the types of industrial location by the concept of export-base theory, and studied actual location behavior about each plant management. (3) Predicted the optimum allocation of nucleus industry, and investigated the related industries about the possibility of relocation apart from great urban area.
In the studies of regional science, various kinds of index or coefficients have been used, so as to measure and describe the extent of areal concentration in economic and other phenomena. The present paper relates to such measures as location quotient, coefficient of localization and localization curve, because they are frequently applied to the actual data for that purpose. One of the substantial personal anther's contribution is a study into the way how the state of localization should be expressed with the above-mentioned measures. This direction of research also connects with the basic problem of concentration, and a new method of deriving a frequency distribution from Lorenz curve of regional origin is discussed at length. This must be another author's contribution toward the betterment of regional analysis, because such a topic has never attracted general attention and never been touched by research workers. Some topics which cannot be discussed in the scope of this paper will be published in author's future work.
Since the industrial revolution the location of industry concentrated on the coalfields and in the port and London. After the first World War world economic circumstances were quite unlike those of the previous century. The industrial development elsewhere in the world had a profound effect upon the economy of Great Britain. There was the decay of older industries, especially on the coastal coalfields, then were the distressed areas. The Government took powers to provide assistance in bringing work to such ‘special area.’ Since the second World War, Great Britain has experienced full employment. According to the changes in techniques and the revolution in transport, however, there were the changes in Great Britain's industrial structure and distribution. Such changes produced also the distressed areas and a boom area. The former are ‘special areas’, now ‘development area’, and the latter are South East England. Government Papers, such as ‘Central Scotland’ and ‘North East’ and ‘South East Studies’, were published. We will be able to compare so-called ‘Tokaido Megalopolis’ with South East and coalfields, for instance Kita-Kyushu and others, with such development areas.
