Abstract
This paper empirically surveys the trade-off relationships among freights coming in and going out of 23 old railroad stations in Tokyo, from 1913 to 1936. To make clear the localized concentration of railroad stations, their freights are applied to the Gini coefficient and find which factors affect those stations to become locally concentrated. In this research, it is shown that most freights were concentrated in the seven stations of Shiodome, Ryokoku, Iidabashi, Kinshicho, Shinjuku, and Shinagawa. In the research, result show that the economies of scale in Tokyo existed and they were mainly affected by those seven stations. It appears river vessels played the main role, much larger than other vehicles, but the trend of railroad trains show that they followed the river vessels.
