Abstract
This paper aims to measure changes in economic dependency and the induced environmental effects between two cities with multiscale Input-Output tables during the priod between 90/92 and 95/97. The empirical analysis is conducted for the case of Tokyo and Beijing. First, we found that the trade between Tokyo and Beijing has increased more than two times in five years and the expansiong of export from Tokyo to Beijing are relatively larger. As a result, the gap of induced environmental impacts between Tokyo and Beijing is slightly scaling down. However, the induced environmental impacts in Beijing per unit export Tokyo become worse which leads to a conclusion that relative gap of environmental impacts between Tokyo and Beijing is still seriously large. This is one of main frivers to enlarge environmental impacts together with rapid increase in export from Tokyo to Beijing.
