I studied on the urban land price gradients and on the factors affecting their fluctuation in the Tokyo Metropolitan cities, and reported the results of the studies at the First Pacific Regional Science Conference. Then, I attempted to find out the relation between the rates of changes of gradients and the patterns of urban developments and the types and amounts of public investment for these 34 cities. The causes which will decide the fluctuations of the gradients seem to be not only the types and amounts of public investment or patterns of urban developmen but also rates of growth or the modes of distributions of urban population of the cities. But, such a presupposition had not been completely confirmed in the research above mentioned.In this paper, I attempted to clarify more distinctly the causes of the fluctuation of the land price or its gradients in the relation to the industrial structure, population density, residential distribution, and distribution of public investment, by intramural investigation using more detailed statistics per square kiro-metre than above-mentioned inter-cities investigation. I measured the gradients of land prices along 5 lines of railways during 8 years in the city of Yokohama. At the same time, we could measure the gradients of population density and their fluctuations along the same lines. Then, we could find out more clearly the relations between the flcutations of land price gradients and the fluctuations of population density gradients. And I could test the presupposition that causes affecting the land price gradients due to the distribution of population, public investment on road or other public transportation systems along the directions, that is the pattern of urban development.If we could advance this investigation more in detail considering this paper as a progressive paper, we might use the confirmed relationship for the political purpose of land use planning or city planning, by clarifying the relationship between the index of the land use density such as population density or public investment and the land price.
