摘要
烟草行业是我国国民经济的支柱产业之一,受诸多外部因素的干扰,无法定量分析烟草需求量。为了解宜昌市当前卷烟需求消费状况,揭示宜昌市卷烟需求与其主要影响因素之间的关系,本文调查收集了2005—2013年宜昌市卷烟需求量状况和主要经济指标资料,并综合可拓聚类预测等模型,结合MATLAB、SPSS和EXCEL等软件,对卷烟需求量的问题进行了多角度的分析,并给出了利用理化指标预测卷烟需求的模型,在文章的最后对模型的适用范围做出了推测,在实际应用中具有较大的参考价值。
The tobacco industry is one of the pillar industries of the national economy. Interfered by numerous external factors, it is difficult to quantitatively analyze the d tobacco demand. To understand the current demand and consumption situation of cigarettes in Yichang and reveal the relationship between the demand for cigarettes in Yichang City and its main influencing factors, the paper surveyed and collected the cigarette demand status and main economic indicators information of Yichang City from 2005 to 2013, integrated the extension classified prediction model, combined with MATLAB, SPSS and EXCEL software, analyzed the demand for cigarettes from multiple perspectives, and proposed to use the physical and chemical properties to predict the demand model for cigarettes. In the last this paper predicted the applicable range of model, which has great reference value in practical applications.
