Literature study，logical analysis and empirical analysis were adopted to understand the theories and core ideas of “New Normal” and “Supply Side Reform” and to shed strategic enlightenment on the future development of public hospitals. The research showed that “Supply Side Reform” under “New Normal” was supposed as a developing economy reform model of all-in-all enhancement of productivity and the logical starting point of the reform and innovation for all industries. There are ineffective supply and less effective supply in China’s public hospitals. Combined with the reform practice of the affiliated drum tower hospital of Nanjing University medical school，the research suggests that，facing the important strategic opportunity period for future development，public hospitals must keep in step with current reform requirements，make self-orientation clear，do “Four Transforms”，improve supply capacity from six aspects and also consider “Demand side”，so as to promote the development of the hospital from the management system and mechanism，to lead the progress of Medicine，and to move towards to a healthy Chinese dream.
