Abstract
In many cases, an input-output framework constitutes an essential segment in a metropolitan simulation model. As the study area of such a model tends to be relatively small, it is usually difficult to obtain the input-output table of its own. This study is aimed at proposing a nonsurvey technique to modify the input coefficients and unit converters for final demand items to meet the demand-supply structures of the area from a table compiled for a larger area. The method combines the RAS and Fratar techniques to modify both coefficients jointly. Despite its simplicity that it disregards the differences in the value added inputs, it could significantly improve the product projection when applied to the Tokyo metropolitan area. In addition, a simple calculation procedure to obtain commodity-based inflaters which are required to evaluate products in real terms is also presented.
