Trial calculation of dining table self-sufficiency ratio : Consideration of self-sufficiency ratio from Hokkaido's dining table

In this paper, using the dining table in Hokkaido as a case example, we calculated teh dining table self-sufficiency ratio as an indicator that recognizes the degree of local production for lacal comsumption. As a result, the Hokkaido's dining table self-sufficiency ratio was calculated to be 53.4%. As compared to the Hokkaido's food self-sufficiency ratio which indicates the self-sufficiency rate at the production stage, the Hokkaido's dining table self-sufficiency ratio indicating the self-sufficiency rate at the consumption stage is low. The reason is that the finally consumed food is not only food produced in Hokkaido, but also includes food produced in other prefectures and foreign countries.
