Based On Diagonal Clustering Method Of Price-supply-demand Evaluation Research And Application

In a market economy, the role of prices in allocating resources more and more obvious, especially under the premise of precision marketing, companies need to grasp the state of the market, and quickly make a countermeasure response. Good or bad performance of a target product in the state of the market requires not only the qualitative judgment needs the quantitative calculation of mathematical formulas, which requires the evaluation of the target commodity market status indicators of the performance of the merits of the system, and then by further cluster analysis of the indicator system to generate the information we need. Specifically, the main job of the following aspects:(1)Establish the price-supply-demand associated modelTo analyze factors affect the price, supply and demand basis, around the interaction between the three elements of the association model, constrained relations to each other a study to determine the price sensitivity of supply and demand as well as analysis of the supply curve and demand curve the equilibrium price and quantity.(2) Build state of the commodity market evaluation index systemAffect the price of supply and demand of many sales indicators, screening and clustering analysis, to build a price index and the demand index, and define the algorithms and the scope of the two indices, at the same time constitute the index of each indicator threshold, calculate the range to determine.(3) Create a seven-state clustering modelFor evaluation of the price of supply and demand, the price index for the abscissa, and the demand index for the vertical axis coordinate system, the performance of the merits of the target product in the market, the different market status of the target product, plane coordinate system is diagonally divided into seven regional, according to the definition of the actual situation in different regions of the qualitative adjustments.The paper also carried out instance argues that the preliminary validation clustering model proposed state evaluation and seven districts, in line with the actual sales.
