Abstract
Some people insist that we should improve the rate of cereal self-sufficiency, but they are not clarifying persuaded levels about the rate of cereal self-sufficiency. Originally, the optimal cereal self-sufficiency that should be targeted is the one to be decided in consideration of various factors like the climate, the geography, and the economical situation, and so on.
In this paper, I examined to estimate a standard cereal self-sufficiency using a characteristic approach, based on some variables that seemed to determine an optimal rate of cereal self-sufficiency. As a result, the best rate of the self-sufficiency of our country was observed from 30 to about 40%.
