In the context of international competition，global competition policy for the digital economy has undergone important changes in both theory and practice. The New Brandeis School has criticized the Chicago School’s antitrust goal of consumer welfare，and advocated the “reconstruction of roots and branches” of antitrust theory，which has also affected the antitrust regulation of the digital economy in the United States，the European Union and other jurisdictions. Based on China’s digital economy antitrust practice，the most critical issue of competition governance is how to correctly understand the digital “gatekeeper” regulation，scientifically promote the normalization of regulation and strengthen the competition assessment of innovation impact. Based on the national strategy of high-quality development and optimizing and strengthening the digital economy，China should avoid adopting the digital “gatekeeper”-style structuralist regulation，promote the stable and predictable，scientific，professional and prudent，multi-tool and full-chain normalized regulation，view the competitive impact of innovation from the perspective of long-term competition，and further strengthen digital competition policy through international cooperation and dialogue.
