In this study, we aimed to build the basic calculation model for linkage effects of fishery industry among Korea, China and Japan. For the calculation, we reconstructed the asian international input output table, and on the basis of the reconstructed table, we made some analyses on the inter relations among 3 nations focusing fishery industry. As the results, some positive backward linkage effects of the fishery industries were found among 3 nations, and especially, production inducing effect of Chinese fishery industry to Japanese supplier was remarkable.
