This study is aimed at proposing a model which can be used in evaluating a project to improve the trunk-line transport facil- ities in countries where such are in short. The model could generate a set of regional I-O tables from the national one and limited regional statistics. It explicitly considers the price differentials among regions, which are relevant to the interna- tional trade theory. After formulating the model, we assess the effects of fictitious improvement in the aggregated rail network in China on the bases of her 29 provinces. Although our calculation is confined to the fixed national table, the spatial distribution of economic indices is evaluated through concentration indices and location quotients with which we can assess whether the project demotes the regional disparities.
