| Research Abstract |
A rapid population decrease happens in Japan as a result of the fertility decline. There is no problem in population decrease itself from the viewpoint of the resource allocation. Econom ical and/or social strains may occur in the transitional phase. The population is changing qualitatively, too. A decrease in labor force alters production and demands for goods and services. On the other hand, the increase in fossil fuel consumption, which caused by population growth and improving living standards in developing countries, is more important issue for the entire world. This is the reason why a phrase "quantitative and qualitative change in the population" is included in the title of this research instead of a phrase "declining birthrate and an aging population". "City structural analysis" and "dynamics analysis" are other main keywords. In traditional urban planning and land planning in Japan, assuming economic growth, the goal was maximizing social welfare. We should focus on quality and selective withdrawal in the future. This study aimed at a comprehensive study on analysis and evaluation techniques appropriate for the situation of population decline.
This research report includes 11 theoretical or empirical articles. They are related with any of the three keywords. We classified the nine thesis based on modeling the space, and composed three chapters of them. These are (1) analysis of changes in the urban population, (2) dynamic analysis model of regional population change, and (3) a spatiotemporal analysis of discrete-space model. Another chapter is composed of two papers in which the falling birthrate and aging are analyzed from original aspects. Quantitative and qualitative changes in the population are the theme that is important in both the land development program and the macroeconomics. We are going to continue a multidirectional study aiming at more useful result.
