基于服装单品类价格需求分布的研究

Research Based on the Price Distribution of Clothing Single Category

摘要: 服装企业具有销售提前期，需基于市场需求提前做好销售规划。基于市场小生境理论，并聚焦于零售服装领域，分析了服装单品类形成的细分市场以及基于价格维度的需求分布。以零售服装企业的销售数据集为例，选择伽玛分布密度函数、Logistic分布函数、正态分布函数作为参数模型，采用极大似然估计方法，利用Python软件进行需求分布拟合。结果表明，对于服装单品类细分市场，价格与销量的关系可以用伽玛分布密度函数来描述，基于此需求分布可为企业销售规划提供一定指导。

Abstract: Apparel companies have a sales lead time, and they need to make sales plans in advance based on market demand. Based on the market niche theory and focusing on the retail clothing field, this paper analyzes the market segments formed by clothing single categories and the demand distri-bution based on the price dimension. Taking the sales data set of a retail clothing company as an example, we select the gamma distribution density function, the Logistic distribution function, and the normal distribution function to fit the demand distribution of the outerwear category. The re-sults show that, for the clothing single category market segment, the relationship between price and sales volume can be described by the gamma distribution density function. Based on this de-mand distribution, it can provide certain guidance for corporate sales planning.
