Abstract
In this Paper, a method for estimating Chinese interregional input/output table is proposed and it is shown that Chinese input/output table in the province levels can be estimated by using 30 provincial input/output tables. As the results, it is cleared that economic development in the costal region depended upon the export and that it influenced to all other regions in China. In addition to this, it is shown that there is no relationship between provinces in inland regions, which is observed in the costal regions.
