Abstract
Spatial economic equilibrium model requires a inter-regional trade data as monetary term by Input-Output table. However, we only have the Input-Output table on the among nine region data in Japan. We need to prepare the another index to apply the economic equilibrium model, because the empirical policy analysis requires at more subdivided regional data. This paper shows the characteristic comparison between statistical data on inter-regional trade/freight data and inter-enterprise data as another index. At a conclusion, although we show the inter-regional freight census data by MLIT and inter-enterprise data by TDB is effective index to subdivide into small region, they have some problem. In this paper, we propose some measures to mitigate those problem at empirical analysis.
