Abstract: Non-survey methods have been developed for estimating regional input--output tables; however, there is ongoing debate about the necessary assumptions and their accuracy. To address these issues, this study presents a deep learning method for estimating regional input--output tables. First, regional quantitative economic data are augmented by linear combinations. Deep learning is then applied to the items in the input--output table, treating each item as the target variable. Finally, regional input--output tables are estimated through matrix balancing based on the predicted values from the trained model. The estimation accuracy of this method is evaluated using the 2015 input--output table for Japan as a benchmark. Compared with matrix balancing under the ideal assumption of known row and column sums, our method generally demonstrates higher estimation accuracy. Thus, this method is anticipated to provide a foundation for more precise estimates of regional input--output tables.
