考虑平台赋能的竞争型电商供应链决策研究

A Study of Competitive E-Commerce Supply Chain Decision-Making Considering Platform Enablement

摘要: 近些年，电商平台企业纷纷凭借自身数字化的优势赋能供应链企业，这极大地影响了供应链成员的决策和收益。本文将电商平台赋能和中小零售商数字化投入纳入到竞争供应链，我们研究了电商平台赋能和可竞争市场如何影响供应链的决策，实现供应链成员的共赢。本文结果表明：(1) 当数字化成本不高时，零售商才会接受电商平台的数字赋能。(2) 中小零售商在接受数字赋能后倾向于降低自身的数字化投入水平。(3) 数字赋能行为是“双刃剑”，一方面能提高供应链效益，另一方面会造成平台滥用市场支配地位，需要从政府规制和市场约束出发，共同推进平台经济的健康发展。

Abstract: In recent years, e-commerce platform companies have been empowering supply chain companies with their digitalization advantages, which greatly affects the decisions and benefits of supply chain members. In this paper, we incorporate e-commerce platform empowerment and small and medium-sized retailers’ digitalization inputs into a competitive supply chain, and we investigate how e-commerce platform empowerment and contestable markets affect supply chain decisions and achieve win-win outcomes for supply chain members. The results of this paper show that: (1) Retailers accept digital empowerment from e-commerce platforms when the cost of digitization is not high. (2) Small and medium-sized retailers tend to reduce their level of digital investment after accepting digital empowerment. (3) Digital empowerment is a “double-edged sword”: on one hand, it can improve supply chain efficiency; on the other hand, it will cause the platform to abuse the dominant position in the market, and it is necessary to start from the government regulation and market constraints to jointly promote the healthy development of platform economy.
