Internet platforms have demonstrated unique advantages such as resource concentration， efficiency improvement， and multiple connections in mutational situation. Exploring how Internet platforms can make full use of platform advantages to quickly respond to environmental changes is an important issue worthy of the attention of industry and academia. It selected WeDoctor as the research object and explored the enabling mechanism of the Internet platform in mutational situation， by analyzing the empowerment process of the platform respond quickly to the mutational situation. It finds that： the platform’s response shows a phased evolution from emergency response to plan response in mutational situation， and the empowerment process is the key to the platform’s rapid response to mutational situation； the empowerment process of the platform builds an interactive context for value co-creation for the platform and platform participants. The transition of platform empowerment level will be promoted in the interaction with the enabled person； the platform’s empowerment mechanism for rapid response to mutational situation appears to be platform value enhancement realized by interaction between empowerment. It extends the traditional research context of empowerment theory to the discussion of emergency decision-making， broadens the interpretation boundary of empowerment theory for the rapid response behavior of the platform， and contributes to the deconstruction and deepening of the internal logic of the empowerment process.
