The Construction and Application of an Analyzing Combinatorial Model on the Relation between Fruits Supply and Demand
水果供给与需求关系组合分析模型的构建及应用

In order to analyze the relationship between fruits supply and demand,On the basis of combining the expectation theory with the experience deducing,an analyzing combinatorial model on the relation between fruits supply and demand is developed in this paper.Taken grape as an example,the model on the relation between grape supply and demand in China was set up,and the relation among grape supply,price and demand in China is analyzed.The result shows that the supply,price and demand of grape have remarkable connections with their former status.The price of substitute products has remarkable influence on grape price,but has no obvious influence on the supply and demand.However the import also has a visibly negative impact on the domestic grape market.And the export and processing have no positive influence on the increase of the aggregate demand for grape.In additional,the increase of grape supply does not necessarily lead to the falling of grape price.Finally,characteristic of grape market and the problems existing in China are probed.
