This paper report the data analysis of the annual reports of the medical and health agency （health and family planning statistics1-1 statements） and the first page of medical records （health and family planning statistics4-1 statements） of the secondary hospitals in 2016. The disease，surgery and operation were classified according to ICD-10 and ICD-9-cm-3. Comparative analysis was carried out from the three dimensions of medical service ability，quality and efficiency. The data was used to measure the true level of hospitals and to help private secondary hospitals find their own position.

The results suggest that most private secondary general hospitals have smaller scale，fewer medical personnel，fewer outpatient visits and patients，fewer bed utilization ratio，and their medical quality and medical services are weaker than that of public hospitals. But their medical efficiency index is obviously superior to that of public hospitals because they are more concerned with cost control and economic benefit. Compared with public hospitals，private hospitals have the advantages of flexible mechanism，strong resilience and innovative motivation. The results show that the gap also indicates that private hospitals have a lot of space to improve the medical ability and quality of medical care.
