Abstract: Internet healthcare is conducive to promoting the reform and innovative development of the medical and health industry, and is of great significance to improving the medical level of people's livelihood in China. Firstly, this paper briefly reviews the development process of Internet healthcare based on the practices of Internet healthcare development in China. Then, based on the multi-source model theory put forward by Kingdon, this paper constructs the dynamic mechanism and path optimization analysis model of Internet healthcare development, and analyzes the dynamic mechanism of Internet healthcare development from the problem source, policy source and politics source in a holistic and multi-stage way. Studies have shown that the catalysis of people's livelihood needs, focus events and policy feedback is the fundamental driving force for the development of Internet healthcare; the attention of government personnel, experts and scholars and practitioners in the medical industry is the main driving force for the development of Internet medical care; the CPC’s ruling idea and the guidance of public opinion are the key traction for the development of Internet healthcare. Finally, based on the investigation of the dynamic mechanism of the development of Internet healthcare, this paper puts forward some suggestions to promote the further development of Internet healthcare, including: establish a problem-oriented notion, and promote the deep connection of top-level design and bottom-level practice; improve the decision-making mechanism, and broaden channels and build consensus; persist in ideological guidance and consolidate the foundation for ideological construction and public opinion response.
