Abstract: During the outbreak of new coronavirus, the advantage of online healthcare became prominent, and many patients resorted to online medical resources. Online healthcare platforms have become an effective supplementary medical treatment channel for medical institutions. Under the background of uneven distribution of healthcare resources in China, the key to solving the difficulty of seeing a doctor is to formulate reasonable policies to guide the development of online healthcare platform. This paper constructs a two-channel medical service supply model to explore the performance of single protection policy and combination protection policy on protecting online medical platform, and to find out the most suitable protection policy. The results show that when the service quality ratio between online medical platform and offline hospital is low, combined protection policy performs better than single policy because combined protection policy can not only expand the market demand of online medical service, but also reduce the government's financial expenditure. On the contrary, when the ratio of dual-channel medical service quality is relatively high, single price policy performs better than combined protection policy. This paper extends combined protection policy to the research of spatial competition model to explore the impact of government policy on the performance of online healthcare platforms. The results of our study not only help expand the relevant research on the combination of policy intervention under the background of dual-channel service supply, but also provide policy recommendations and theoretical guidance for China's medical reform and the development of online healthcare.
