In scale expansion, digital platforms have jumped out of the constraints of production and transaction costs to a certain extent, but they have encountered surging social costs. Unlike previous enterprises, the digital platform is the organizational form of the online trading market, the maker of market rules, and the defender of market order. Based on the theory of social operating finds that, due to the organizational attributes and structural advantages of digital platforms, the digital platform is related to the vital interests of the general public, which is prone to large-scale conflicts of interest and social stability if poorlyhandled. At the same time, it needs to respond to all parties’doubts about their market rules. Moreover, as an integrator of data and technology, it relates to the security of national data and the core competitiveness of the country. It is necessary to highlight the public nature,coordination, fairness, and security of the platform and to assume more responsibilities for maintaining social order.
