小作料と農地価格の市場構造論的分析

Abstract

Land lease markets are classified into oligopoly, oligopsony and bilateral oligopoly. Recently, rent and farmland value in oligopolistic market are on the decline owing to the stagnation of rice price and off-farm employment. Land lease contracts in the market are decreasing with the drift of the off-farm labour force into the agricultural sector. It is a problem that high percentage of the rent comparing with gross income continue to remain in the market. In oligopsonistic markets, rent and farmland value are an upward tendency in the market where land lease contracts are decreasing with the drift of the off-farm labour force into the agricultural sector. On the other hand, rent is on the decline in the market where the contracts are increasing with the drift of the farm labour force into the secondary and tertiary sectors of the economy. But farmland value is an upward tendency in this market that is another problem. Finally two plans to work out these problems are suggested.
