While, in large scale multiple farmers, producing rices and facility cuture vegatables, a rise of the price of current inputs has a good effect on it. (2) In large scale multiple farmers, producing rices and open cuture vegeta-bles, the economic efficiency improvement changes the source of economies of scope from the effective use of the land to the effective use of the capital. While, in large scale multiple farmers, producing rices and facility cuture vegetables, the economic efficiency improvement changes the source of economies of scope from the effective use of the labor to the effective use of the current input. 3.Empirical analysis of the business performance and diversification in General Agricultural Cooperatives : The diversification in General Agricultural Cooperatives has a good effect on the stabilization and efficien-cy of the business.
