With the flourishing of e-commerce industry, online short-rent—a brand-new business model, has begun to enter people’s vision. The entry into force of the Electronic Commerce Law in 2019 also marked that the online short-rent industry has formally entered into a standardized governance track. As far as C2C model is concerned, the private law attribute of online short-rent platform has not changed, and it is essentially still a commercial intermediary in housing leasing. Besides keeping regulation of private law, we should strengthen the macro-regulation construction based on the general layout of the Electronic Commerce Law. In other words, to provide a holistic scheme for resolving externalities and avoiding endogenous risks in the industry, we should start with perfecting the supporting system, building industry self-discipline mechanism and speeding up the construction of credit system. Finally, we can realize the blueprint of the modernization of the national governance system.
