From April to June in 2017，China Hospital Association-Private hospital branch and Martec Shanghai jointly conduct a market research project for 214 private hospitals from different grades and types. We segment the private hospitals by three types：premium，public equivalent and public supplementary and analyze the purchase volume and purchase mode for each group. The aim of this study is to find out the difference of purchase mode and volume for different segments and help these private hospitals to better manage their supply chain management，as well as to provide strategic recommendations for them.
