The rapid development of digital capitalism has laid the social foundation for the emergence of the techno-feudalism. Cedric Durand brought techno-feudalism into the public spotlight, providing a theoretical framework for understanding and analyzing the phenomena of capitalist digital technology. Evolved from technological accelerationism, techno-feudalism is closely linked to the alliance between technology and capital, which enables tech giants to monopolize political privileges, the unlimited expansion of “technological fiefdoms” driven by the growth of digital platforms, and the “cloud rent” underpinned by intellectual property rights. The political, economic, and cultural transformations of digital capitalism collectively shape the techno-feudalism social ideology. From the critical perspective of Marxist political economy, it becomes evident that the political privileges of tech giants are essentially a product of the marriage between capital and technology in the era of digital capitalism; the integrated development of information and data is a necessity for the growth of the digital information industry and the emergence of new sectors; and the rental value of intangible assets reflects capitalists’ pursuit of surplus value. By controlling key technologies and data resources to generate profits, tech giants neither transcend the theory of surplus value nor alter the traditional capitalist production relations. Techno-feudalism is, in essence, a sub-form of digital capitalism. Therefore, clarifying the evolution and nature of techno-feudalism, drawing lessons from experiences that benefit the development of China’s socialist digital economy, and strengthening digital economy construction through socialist democratic politics, the guidance of shared capital, and the development of data platforms hold significant theoretical and practical importance for exploring a new form of digital civilization with implications for human civilization.
