平台补贴对电商市场竞争与商家行为的影响研究

The Impact of Platform Subsidies on Market Competition and Merchant Behavior in E-Commerce

摘要: 随着数字经济的迅速发展，电子商务平台在国民经济中的地位不断提升，逐渐成为商品流通的重要载体。在平台竞争日益激烈的背景下，各大电商平台纷纷通过补贴策略吸引消费者和商家参与，形成以价格竞争为核心的市场格局。本文基于平台经济理论与市场竞争理论，从平台、商家与消费者三方关系出发，系统分析补贴策略对市场竞争格局及商家行为的影响机制。通过理论分析与案例研究相结合的方法，本文发现：平台补贴在短期内能够显著降低商品价格、刺激消费需求并扩大市场规模，但长期来看可能导致商家利润压缩、市场竞争加剧以及平台依赖增强等问题。此外，过度补贴还可能引发价格扭曲与资源配置效率下降。基于上述分析，本文提出优化补贴结构、促进差异化竞争以及完善市场监管等政策建议，以推动电商市场实现可持续发展。

Abstract: With the rapid development of the digital economy, e-commerce platforms have become increasingly important in the national economy and have gradually evolved into a major channel for commodity circulation. In the context of intensifying platform competition, major e-commerce platforms widely adopt subsidy strategies to attract both consumers and merchants, thereby forming a market structure characterized by price competition. Based on platform economy theory and market competition theory, this paper analyzes the impact mechanism of subsidy strategies on market competition and merchant behavior from the perspective of the tripartite relationship among platforms, merchants, and consumers. By combining theoretical analysis with case studies, the results show that platform subsidies can significantly reduce product prices, stimulate consumer demand, and expand market scale in the short term. However, in the long run, such strategies may lead to profit compression for merchants, intensified market competition, and increased dependence on platforms. In addition, excessive subsidies may distort price signals and reduce the efficiency of resource allocation. Based on the above findings, this paper proposes policy recommendations, including optimizing subsidy structures, promoting differentiated competition, and improving market regulation, in order to support the sustainable development of the e-commerce market.
