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
