果树投入产出模型及应用的研究——Ⅲ.模型应用的实例分析

本文结合对南口农场二分场果树投入产出情况的调查,研究了不同时间段分场果树投入产出的模型,拟合出产量,产值,利润分别对投入因素的柯布—道格拉斯生产函数关系。分析了各投入因素的生产弹性。寻求出各时间段农场在果树生产中最大效益投入因素和制约产量,产值和利润提高的投入因素。为农场的果树生产计划的制定与实施,提高投产比例提供理论和实际生产依据。

STUDY ON MODELING THE RELATIONSHIP OF INPUT-OUTPUT AND USING INPUT-OUTPUT MODEL IN ORCHARD Ⅲ.input-output model in farm orchard

The stimulation was made on input-output framework in farm orchard.Theoutputs were included in the fruit production, output value and net income and the inputswere included cost of the labor, the fertilizer, the electric and irrigation, the practics of ma-chinery, the overhaul depreciation and the management. The relationships of input-outputwere estabolished based on Cubb-Doglas model. The limit factors and the optimum fac-tors of input in given date of farm orchard were studied by the marginal analysis, whichprovided basis for increasing the ratio of the input-output and working out a plan of theproduct and management in farm orchard.
