Competing in Digital Markets: A Platform-Based Perspective
提出基于平台的竞争视角，区分三种平台市场，引入平台身份概念，从平台规模和身份两个维度解释数字市场的竞争动态，对研究平台战略的学者有参考价值。
The digitization of the economy is altering the nature of competition, affecting the fundamental way firms compete in digital markets. In this article, we offer a platform-based view of competition in digital markets, present three distinct types of platform markets, the key elements affecting the value of a platform-based service, and the competitive logic that shape competition in these markets. We introduce the concept of platform identity to delineate the platform’s technological and market profile delineating the platform’s competitive identity domain and distinguish it from platform size (which reflects the scale of its user and complementor network). We argue that each platform has a unique identity, and comparisons of rival platforms along these two strategic dimensions—platform size and platform identity—help to explain the nature of competition in digital markets and explain the unique competitive dynamics that depart from mainstream competitive theory’s predictions. Our framework also helps to identify cases where the market boundaries and competitive domains become contested because of platform competition, leading to market convergence. We discuss how the proposed framework can enrich and extend existing theory on competitive dynamics to the context of digital markets, and offer a foundation for future research.
