When a multi-regional and multi-asectoral economy exists, there are many input-output tables at different levels of aggregation. A nm-dimension table for n-regions and m-sectors, a n-regions table, a m-sectors table and finally a one-region and one-sector (or a multiplier). This paper discusses how these tables can be consistent each other and what are the consistence conditions when final demand changes. First paper clarifies the conditions of consistent aggregation when bottom up approach is adopted, and shows the prediction errors in traditional calculation based on a numerical example. Then it discusses a decision problem in top-down approach, and finally the roles of technological difference and hysteresis in consistency approach.
