回归分析及差分方程关于大蒜产销规律的研究

The Research of the Application of Regression Analysis and Difference Equation in the Regional Garlic Industry

运用差分方程和回归分析方法,对当地大蒜产业的种植面积和销售价格的波动规律进行研究,得到一些有实际意义的结果:大蒜的价格与需求和供给均接近线性关系,分别为递增和递减;价格与产量的波动规律有稳定型、发散型、封闭型三种情况;大蒜产业的价格和种植面积的波动接近封闭型循环,需采取综合性改革措施,才能逐步趋向稳定。

Investigating the fluctuation law of the regional garlic industry＇ s planting acreage and marketing price by a way of difference equation and regression analysis, some practical results are received ： the associations between the garlic＇s price and the demand and supply are all close to be linear, the formal one increasing progressively while the latter one decreasing progressively; The fluctuation law of price and yield has three situations including the stable pattern, divergence form as well as enclosed type; The garlic industry＇ s price and planting acreage fluctuation approach a enclosed circulation, which is needed to take a measure of a comprehensive reform to make it tend to be stable gradually.
