摘要:

近年来社交电商的兴起得益于多种营销组合方式的推陈出新,其中拼团模式针对不同特性消费者进行精准营销,兼具社交属性和区别定价属性,已成为时下最有效的营销模式之一。本文通过对比统一定价模式与提供拼团渠道的差异定价模式,综合考虑消费者异质性和消费者特征信息有价获取,在信息不对称下,为商家和平台两个主体构建拼团条件、拼团定价与拼团规模的最优决策模型。模型将消费者分为拼团偏好型和等待厌恶型,分析潜在消费者规模、消费者组成和成团成本差异对商家决策的影响。在得出各模式下最优定价组合和拼团规模的精准决策后,本研究还发现:(1)当等待厌恶型消费者占比略高时,依然提供拼团选项不但没有降低品牌价值,反而使商家与平台利润同时上升;(2)消费者异质性越明显,越可以从开通拼团渠道中获利;(3)平台收集的消费者占比信息对大型商家有更显著的影响,随着等待厌恶型消费者占比的增大,商家应该拉大定价差异,并设置较大的拼团规模;(4)在一定范围内,平台可以通过信息有价售卖的方式获得额外利润,但商家对市场预测能力较低时,平台选择无偿共享信息反而可以实现平台-商家双方的共赢。

Abstract:

The rise of social e-commerce has benefited from innovative marketing strategies. Among them, group-buying model is a precise marketing strategy that targets consumers with different characteristics. It has combined social attributes and differentiated pricing properties, making it the most effective marketing model today. An optimal decision-making model for merchants and platforms is provided under information asymmetry by comparing uniform pricing models with differential pricing models that provide group buying channels. The model has taken into account consumer heterogeneity and valuable consumer feature information to offer optimal group buying conditions, pricing, and scale. It has also categorized consumers into group-buying preference type and waiting aversion type, analyzing the impact of potential consumer scale, consumer composition, and differences in group formation costs on business decisions. After obtaining precise decision-making on optimal pricing combinations and group-buying scales for each mode, it is found that (1) when the proportion of waiting aversion consumers is slightly higher, providing group-buying options not only does not reduce brand value but also increases both the profits of businesses and platforms. (2) The more pronounced the heterogeneity of consumers, the more profit can be gained from opening group-buying channels. (3) Information on consumer proportions collected by platforms has a more significant impact on large-scale businesses. As the proportion of impatient consumers increases, businesses should widen pricing differentials and set larger group-buying scales.(4) Within a certain range, platforms can obtain additional profits through selling valuable information. However, when businesses have low market forecasting capabilities, choosing to share information with them for free can actually achieve a win-win situation for both the platform and the businesses.
