Abstract: The formation mechanism of monopoly profit in digital platforms is able to answer the question of “what is the cause” of monopoly profit, which is the same as the research theme of Western industrial organization theory. Based on the basic principles of the Marxist theory of monopoly capital and the existing literature both at home and abroad, this paper establishes a Marxist analytical framework of the formation mechanism of monopoly profit, which is used to analyze the formation mechanism of monopoly profit in digital platforms, and finally forms a Marxist paradigm of industrial organization theory. Comparing the industrial organization theory in the Marxist paradigm and in the neoclassical paradigm, we can find that certain flaws of the neoclassical industrial organization theory are exactly where the advantages of that in the Marxist paradigm lie. The Marxist theory of monopoly capital based on the labor theory of value is able to analyze the formation process of monopoly profit in digital platforms in more detail, whose explanatory power on a number of issues is no less than or even better than that of the neoclassical industrial organization theory. Based on this analytical framework, we can derive a Marxist antimonopoly scheme for digital platforms, that is, antimonopoly supervision of digital platforms from the perspective of monopoly profit and digital ownership.

Key words: digital platforms, monopoly profit, monopoly capital, the labor theory of value

摘要： 数字平台垄断利润的形成机制可以回答垄断利润“因何而来”的问题，这与西方产业组织理论的研究主题是相同的。本文基于马克思主义垄断资本理论的基本原理，在借鉴国内外最新研究文献的基础上，建立了垄断利润形成机制的马克思主义分析框架，并利用该框架分析了数字平台垄断利润的形成机制,最终形成马克思主义范式的产业组织理论。对马克思主义范式与新古典范式的产业组织理论进行比较可以发现，新古典范式产业组织理论的诸多缺陷，正是马克思主义范式的优势所在。基于劳动价值论的马克思主义垄断资本理论，可以更加细致地分析数字平台垄断利润的形成过程，对许多问题的解释力不亚于甚至超过了新古典产业组织理论。基于这个分析框架，可以得出具有马克思主义色彩的数字平台反垄断方案，即从垄断利润和数字所有权的角度对数字平台进行反垄断监管。
