Starting with Tokaido Shinkansen in 1964, there have been already 92 Shinkansen stations nationwide. However, these Shinkansen stations may not always be built accessible. In this research, we analyzed the relationship between the accessibility of the Shinkansen station and the change of statistical data including population, economics, industry, and land use of the local municipalities where the Shinkansen stations are currently located. We collected many socioeconomic statistics from various sources of cities and towns with 69 Shinkansen stations. We developed structural equation model showing relationship among statistical data. It is found that Shinkansen station with high accessibility can reduce regional decline compared to those with low accessibility.
Benefit evaluation for transport projects has been energetically conducted by applying the SCGE model. In most those researches, transport firm producing transport services has not existed explicitly, so the required transport time reduction occurred by transport projects is assumed to be effective for transport service consumers directly. However, those assumption have three main problems that 1) the effects improved productive efficiency and changes of value added cannot evaluate, 2) the model outputs unreasonable results changing transport costs in proportion to price change of transported goods and 3) spillover effects of changing commodities’ price or wage do not influence to transport production. In this paper, we developed the SCGE model introduced the behavior producing transport services by transport firm. We created the Benefit Incidence Table to confirm spillover effects and indicated consistency to benefit evaluation methods of the Manual of Cost Benefit Analysis in Japan.
