| Research Abstract |
1.Fact-finding explication of common inputs and incentives to diversify the business : (1) It is an imprtant problem for large scale multiple farmers, producing rices and beef cattles, to make sure of intelligence resources, such as a supply route of the high quality dry straw. (2) An excellent, observant eye for the growth of crops and livestock and the ability to infer them overall are essencial as intelligence resources about production technique. 2.Empirical analysis of economic efficiency improvement and economies of scale and scope in large scate multiple farmers : (1) In large scale multiple farmers, producing rices and open cuture vegetables, cetaris paribus, a rise of the wage or the price of capital services has a good effect on improving the economic efficiency. 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.
