摘要： 数字经济时代,数据作为一种生产要素对平台企业的定价决策产生了影响。本文在归纳平台市场发挥数据价值的典型事实基础上,建立数理模型,讨论了数据对不同规模的平台企业的定价及收益影响,并集中讨论了数据量与数据处理技术对定价的影响机制。研究表明,数据对于不同规模企业的定价决策确实有不同影响——在数据支持下,中小型企业倾向于通过提高价格获取更多收益,而大型企业更在乎如何实现完全价格歧视,仅从定价上看,是低于传统垄断定价的。在此基础上,本文认为,应当警惕大型平台企业通过完全价格歧视侵占消费者剩余,并可以通过对中小型企业提供技术支持以促进市场竞争,防止大型企业滥用市场支配地位。

关键词: 平台企业规模, 定价决策, 数据优势, 价格歧视

Abstract: In the era of digital economy, data, as a factor of production has an impact on the pricing decisions of platform enterprises. On the basis of summarizing the typical facts about the value of platform market data, this paper establishes a mathematical model to discuss the influence of data on the pricing and revenue for platform enterprises of different sizes, and focuses on the mechanism of how data volume and data processing technology influence pricing. The research shows that the pricing decisions of companies of different sizes are usually affected by data — with the support of data, small and medium-sized businesses tend to gain more profits by raising prices, while their larger counterparts care more about how to achieve complete price discrimination, which is actually lower than traditional monopoly pricing. On this basis, this paper argues that vigilance should be maintained for major platform enterprises that usurp consumer surplus through perfect price discrimination, and that not-so-large firms can be provided with technical support to promote market competition and prevent those giant corporations from abusing their dominant position in the market.

Key words: scale of platform enterprise, pricing decision, data advantage, price discrimination
