以粮食价格为研究对象,分析探究了我国粮食价格体系的规律、合理收购定价和提升小麦种植面积方案问题·首先,通过数据处理与分析,运用蛛网理论,建立蛛网模型得出我国粮食价格体系的特殊规律;然后,运用优化理论,建立单目标优化模型,结合LINGO软件解出最优解,对“十二五”期间的粮食最低收购价政策进行评价,并对2017年的粮食收购价进行预测;最后,利用数理统计与分析原理,建立多元线性回归模型,得出小麦种植面积的多元线性回归模型,并制定了具体的实施方案.
Taking the grain price as the research object, this paper analyzes the law of the grain price system in our country, rationally acquires the pricing and raises the plan of the wheat planting area. Firstly, through the data processing and analysis, using the cobweb theory to establish the cobweb model, Then we use optimization theory to establish a single-objective optimization model, combined with LINGO software to solve the optimal solution to evaluate the minimum purchase price of grain during the “Twelfth Five-Year Plan”, and estimate the purchase price of grain in 2017 Finally, based on the theory of mathematical statistics and analysis, a multivariate linear regression model was established to obtain the multivariate linear regression model of wheat acreage and the specific implementation plan was formulated.
