 This study investigates the policy interventions, development trends and service innovations of internet hospitals in China, analyzing official policies related to internet hospitals implemented by the government since 2005, collecting data from officially approved internet hospitals and conducting in-depth semi-structured interviews with key stakeholders. The results show that 25 policies promoted the development of internet hospitals in China, public tertiary hospitals led the development of internet hospitals, and internet hospitals mainly played complementary roles to physical medical institutions. However, the service model of internet hospitals needs more distinguished innovations to provide personalized digital health and patient-centric services.
