Abstract
Japan has ever been equipped with some Shinkansen lines as Tokaido, Sanyo, and so on. Other Shinkansen as Hokuriku or Linear-Chuo is planned to be built in the near future. These high-speed rails were designed under Act for Construction of Shinkansen Railway Across the Country. Five of all the planned lines start from Tokyo (Tokaido, Joetsu, Tohoku, Hokuriku, and Linear-Chuo Shinkansen lines), which are in business or under construction. On the other hand, six lines start from Osaka (Tokaido, Sanyo, Linear-Chuo, Sanin and Shikoku Shinkansen lines), while only two lines got in open. Linear-Chuo Shinkansen will be built, which will be completed after 18 years later than the east section between Tokyo and Nagoya. Furthermore, no one knows the open date of the other projects with Osaka. Such imbalance between eastern and western Shinkansen networks might expand the economic gap in these regions. In this research, the main forecast system is named MasRAC (macro economic simulation model system), which is an improved model from the previous macro economic simulations, and which can calculate the effect of nationwide high-speed network on each region. Some economic simulations were made with conditions that Shinkansen network centered on Osaka is built up and the imbalance is disappeared.
