Abstract
In this study, we compared the economic theoretical characteristics of peasant farming with those of capitalist farming, and examined major contemporary Japanese agricultural problems─agricultural land use accumulation, agricultural entry by companies, agricultural products market opening, and rice production adjustment─on the basis of economic principles. As a result, three aspects were clarified. (a) It cannot always be said that large-scale peasant farming is more market-competitive than small-scale peasant farming, and that capitalist farming is more market-competitive than peasant farming, due to the characteristic of peasant farming that “family workforce is not commercialized and ‘v’ has the potential to be reduced”. (b) When market price falls due to the opening of the agricultural products market or the excess of rice, it is possible that withdrawal from production will take place in large-scale peasant farming or capitalist farming before small-scale peasant farming, and in the case of the opening of the agricultural products market in particular, domestic agricultural production may be reduced. (c) The theoretical perspectives derived from such characteristics of peasant farming have an important meaning in analyzing the current state of Japanese agricultural problems.
