分析乳制品与植物基乳替代品细分品类需求结构：考虑预先承诺数量
Analyzing the Demand Structure Associated with a Granular Array of Dairy Milk Products and Plant_Based Milk Alternatives Accounting for Pre-Committed Quantities
摘要
A Generalized Exact Affine Stone Index model is estimated to analyze the demand for dairy milk products and plant-based milk alternatives (PBMAs), applying panel data from 2020 to 2023. One-quarter of white milk and two-thirds of cashew milk consumption are price-invariant. The demands for dairy milk products and PBMAs are inelastic. PBMAs compete against almond milk more than against each other. Specialty dairy products (lactose-free milk, traditional flavored milk, Fairlife, and organic milk) compete more with white milk than with each other. PBMAs are stronger net substitutes for white milk than for specialty dairy products.
中文摘要
本文估计了一个广义精确仿射斯通指数模型，用以分析乳制品牛奶与植物基奶替代品（PBMAs）的需求，并采用了2020年至2023年的面板数据。四分之一的白奶消费量和三分之二的腰果奶消费量不受价格影响。乳制品牛奶与PBMAs的需求均缺乏弹性。PBMAs之间与杏仁奶的竞争程度高于彼此之间的竞争。特色乳制品（无乳糖牛奶、传统风味牛奶、Fairlife和有机牛奶）与白奶的竞争程度高于彼此之间的竞争。PBMAs对白奶的净替代性强于对特色乳制品的净替代性。
