Comparison of Prefectural Input–Output Tables in Japan

Based on the 2011 prefectural IOTs, they were aggregated and compared with the values of the national table after integrating each prefectural table into 80 common sectors. We found that the deviation rate of total production from the national value is less than 1%, the maximum deviation rate by sector is less than 20%, and seven out of 80 sectors exceed 10%, and most of them are within a few percent. As for net exports, their sum should be equal to the corresponding values of net exports on the national table. The total deviation divided by the production was less than 1%, but we found that about nine sectors exceeded 10%. The rate of deviation in the goods sector was relatively small, but the rate in the service sector was large. These rates have improved gradually over time.
