作業受委託と農地賃貸借の展開方向

Abstract

Mainly, land lease markets in Japan are classified into oligopoly, oligopsony and bilateral oligopoly. In oligopsony and bilateral oligopoly, farm land lease and contract farming for part working process have strong competitive relation and farmers' groups encourage the development of contract farming for part working process. Regarding economic conditions of contract farming, on the one hand, profitable condition of contract farming for part working process in rice production comparing with buying the machine is extended. But on the other hand, profitable condition of farm land lease comparing with contract farming for full working process in rice production is extended. Therefore, nowadays when it can be expected, that the rent and the charge of contract farming for full working process are increased, economic conditions for developing the farm land lease are extended. Finally two plans for developing the farm land lease are suggested.
