Economic Impact on Rice Production Cost by Using Large Size Paddy Field Plots and Land Accumulation in Hokkaido

Abstract

The purpose of this paper is to evaluate the economic impact on rice production cost by using large size paddy field plots and land accumulation in Hokkaido. The main outcomes are as follows : First, using large size paddy field plots and land accumulation shortens working hours for rice production. Secondly, they lower rice production cost. In conclusion, under the current policy, using large size paddy field plots and land accumulation is economically effective through expansion of paddy fields.
