Klaassen constructed the model for the analysis of regional distribution of labor force and wage level which is shown by equations (2.1)-(2.6), where the variables used in this model are defined as follows: L : labor force in a region at time 0 L_<-1> : labor force in a region at time -1 L_s : labor force supplied in a region at time 0 L_D : labor force demanded in a region at time 0 L_<DN> : labor force demanded in non-basic activities in a region at time 0 L_<DB> : labor force demanded in basic activities in a region at time 0 Δ^nL : natural increase in labor force in a region during the period from time -1 to 0 M : net migration of labor force (inflow of labor force minus outflow of labor force) in a region during the period from the time -1 to 0 w : level of wage within the region studied w^^- : level of wage outside the region studied Z : a variable grouping all the other "exogenous" variables which independently of wages, influence the level of basic industrial activity in the given region α, β, and γ: parameters. Based on the model, present author has analyzed the mechanism of the determination of the regional labor force in Japan (Keisuke Suzuki, "An Econometric Analysis of the Variation of Regional Population," The Journal of the University of Transportation Economics, Vol. 4, No. 2, 1969, pp. 69-80 (in Japanese), Keisuke Suzuki, "The Variation of Regional Population in Japan," Journal of Regional Science, Vol. 10, No. 3, 1970, pp. 335-351 (in English), and Keisuke Suzuki, "A Study of the Variation of Regional Labor Force by Econometric Models, An Analysis of Regional Labor Force in Japan and United States of America," The Journal of the University of Transportation Economics Vol. 6, No. 2, 1971, pp. 12-29 (in Japanese). The derivative models obtained from Klaassen's model used in the previous studies had a variable which was very difficult to measure. The variable is the variable Δ^nL. In the models used in this paper which are also obtained from Klaassen's model, such a variable is omitted by making a new variable ΔL which is Δ^nL+M. Additionally, in this paper, the variable w^^- is defined as the average of wage level of all regions, and the symbol "-" fixed to a letter is used as the symbol which shows the average of the quantities shown by the letter of all regions. And the variable A which is the level of industrial activity is used instead of using the variable Z which is also slightly difficult to define and measure. Moreover, variable a which is the increase rate of the index of _the level of industrial activity in a region during the period from time -1 to 0, S which is the level of social environment in a region, nad t which is the increase rate of length of roads are introduced. The Greek letters in the models in this paper are parameters. The models used in this paper are shown by equations (3.1.1)-(3.8.8). In these models, the variable a is regarded as the size or the quantity of the opportunity for employment. The reduced forms of these models are fitted to the data of Japan. Model VI was successfully fitted to the data. This fact means that migration of labor force is determined by 3 factors, the regional differences of level of wage, level of social environment, and the size of opportunity for employment. And Model I, II, and IV are also successfully fitted to the data. This means that even if a model is built without the one or two factors among the 3 factors mentioned above, the model is successfully fitted to the data. Additionally, Model VII is also successfully fitted to the data. It is very interesting that the increase rate of length of roa s is the significant factor of the regional distribution of labor force, and the sign of the parameter of the variable t is negative. As Model VII is built for analyzing the data which is obtained from the smaller regions (prefectural data), the fact that the sign of the parameter is negative suggests that the increase of the length of roads mitigate the concentration of labor force into a small area. On the other hand, according to the results of application of Model VIII to the data, the value of the parameter of the variable t is positive, although this value is not significant. As Model VIII is built for analyzing the data which is obtained from wider regions, the fact that the value of the parameter is positive suggests that labor force moves to the wider region where the length of roads rapidly increases.
