摘要
本文通过对数模型将粮食产量和粮食生产成本之间的影响进行度量分析,用对数关系解释了两者之间的相关性;运用Eviews软件对粮食产量和粮食收益进行回归分析,从弹性系数和净收益的角度解释了两者之间的线性影响度,通过利润最大化原则预测了粮农的最优产量,最后对粮食成本、产量、收益三者进行统一分析计量,为促进粮食生产提供了一些建设性对策。
This paper conducts metrics analysis of influence between grain output and grain cost by semi-logarithmic model, and proves the logarithmic relationship between them. First of all, we adopt the regression analysis of grain production and grain profit using Eviews software, and then explain their linear effect in terms of the elastic coefficient and net earnings. This paper also predicts the optimum production according to the profit maximization principle, and analysis the unified measurement on grain cost, grain output and grain profit. At last we put forward some constructive countermeasures for the related grain problems. It aims at breaking the bottleneck of farmers＇ grain yield in elements of grain output and grain cost so as to promote sustainable grain yield efficiently.
