This study aims to identify the relationship between the social changes in population and the urban functions in Japan. The urban function is represented by the employment opportunity by industry, which is defined by the number of jobs per labor force population. The main hypothesis in the study is that the disparities of employment opportunities had been a major determinant factor on social changes in population during the post-war period in Japan.
The study is divided into three main parts. First, the trends in population and migration in Japanese regions are examined for the years 1955-95. Second, the industrial structure and the growth disparities in twenty-six Japanese cities with populations of more than 300,000 are examined by applying the rate-share analysis and the multiple regression analysis for the years 1980-90. Third, the multidimensional scaling method is applied to interregional migration data for 1960-90 to identify the structure of interregional migration as well as to
estimate the hidden distance between regions. The study also estimates the interregional migration model based on the logistic model using factors on employment opprtunity by industry and regional distance derived from the multidimensional scaling method.
The main findings in the study have revealed that the social changes in population during the postwar period had a close relationship with the employment opportunities in advanced tertiary industries, such as wholesale, finance and insurance, real estate and advanced services. Referring the findings in the study, the promotion of advanced tertiary industries in local regions is necessary to redress the concentration of population and migration in metropolitan regions.
