規模の経済性を考慮した生産性の地域別推移と地域間格差の同時分析

―韓国稲作の事例―

We measure regional productivity changes that reflect both economies of scale and multiregional productivity differences, in a case of rice production in South Korea. We calculate the multilateral input-based productivity (MIBP) index and themultilateral output-based productivity (MOBP) index. The results show that average annual growth rates of the national aggregate MIBP and MOBP are each less than 1%.
