Abstract: The disorderly expansion of capital has evolved into a brandnew monopoly model with the superposition of capital, data and traffic flow. The three behaviors, ie. creating structural competitive advantages, building a closed ecosystem and raising market entry barriers, are different from other behaviors designed to thwart competition, with significant characteristics of competition among traffic flows. They are the behavior mapping of the “centerperiphery” system of the digital platform ecology: capital continues to pour in the field of information infrastructure and accelerate the construction of digital essential facilities, and data traffic flows are gathered to form a central platform, through which a pincer attack is loosened against the competitors through diagonal merger; internal selfpreferences but external transaction restrictions lead to a “degradation” of the system structure from the platform to the pipeline, forming a monopoly system of traffic flows; capital solidifies the system with business models and legal regulations that do not conform to the data flow, which makes it difficult for latecomers to break through the data monopoly created by the superplatform through the firstmover advantage and data rules. The innovation highly dependent on data has become an oligopoly game of a few superplatforms. Based on the PDA paradigm of “platformdataalgorithm”, this paper puts forward three regulatory pathways: defining the structural platform from the perspective of the “relational and structural power” of Strange and introducing the principle of the open platform into the Antimonopoly Law; comprehensively transforming the SSNIP and SSNDQ methods tested by the hypothetical monopolist for the two types of platforms, by reforming the transmission mechanism of traffic flows among the center, subcenter, and periphery, since the price mechanism controlled by the circulation organization cannot fully reflect the market supply and demand; validating the data capture methods with two innovations in order to smooth the algorithmic evolution channel blocked by capital.
