引言本研究实证检验了在线零售商销售的电子烟油的价格折扣与产品属性之间的关联。方法 我们分析了 2021 年 4 月至 5 月期间来自五家主要在线电子烟零售商的 14000 种电子烟油产品，以确定价格折扣与产品属性（如尼古丁含量和形式、风味以及植物甘油/丙二醇比例）之间的关联。分析中使用了固定效应模型，折扣以美分/毫升电子烟液量计算。结果 14 407 款烟油产品中，92.5% 为折扣价。平均而言，五家商店的 13 324 种有折扣的产品的价格折扣为 16.84 美分/毫升。在三种形式的尼古丁（盐、游离碱和不含尼古丁）中，盐烟油的平均价格折扣最高。结论 我们的研究结果表明，含盐尼古丁的电子烟油在网上销售时具有较高的平均价格折扣，这可能会影响消费者的购买行为。需要进一步研究来评估这些折扣对青少年和成人烟草使用的潜在影响。政策制定者可能会考虑采取措施限制电子烟油的在线价格折扣，以此作为减少年轻人销售的一种手段。
Introduction The present study empirically examined the association between price discounts and product attributes of e-liquids sold by online retailers. Methods We analysed 14 000 e-liquid products from five major online e-cigarette retailers between April and May 2021 to determine the association between price discounts and product attributes such as nicotine level and form, flavour and vegetable glycerine/propylene glycol ratio. A fixed-effects model was used in the analysis and discounts were calculated in US cents/mL of e-liquid volume. Results Out of 14 407 e-liquid products, 92.5% were offered at a discounted price. On average, the price discount for the 13 324 products that had discounts was 16.84 cents/mL across the five stores. Among the three forms of nicotine (salt, freebase and nicotine free), salt e-liquids had the highest average price discount. Conclusion Our findings suggest that e-liquids with salt nicotine have a higher average price discount when sold online, which may influence consumer purchasing behaviour. Further research is needed to assess the potential impact of these discounts on youth and adult tobacco use. Policymakers may consider implementing measures to limit online price discounts for e-liquids as a means of reducing sales among young people.
