Outline of Final Research Achievements

Spatial economic analysis requires an inter-regional trade data as monetary term like Input-Output table. Although the empirical policy study requires the analysis on subdivided area, however, we only have the Input-Output table on the 9 regional data in Japan. Therefore, this research shows the characteristic comparison between statistical data on inter-regional trade/freight data and inter-enterprise data by using simple statistical methods. As a conclusion, we show the inter-regional freight census data by MLIT and inter-enterprise data by TDB is effective index to subdivide into small region. But inter-regional freight census data is only for the prefectural level, inter-enterprise data can be applied at municipality level although we have to solve some problem to apply the model. Also, we make a model to estimate Gross transport data from Net transport data. It will be help us to estimate some inter-regional trade flow on subdivided are.
