[Purpose/significance] This paper analyses the current situation and changes of the research integrity policy issued by the Chinese central government and the local response, in order to grasp the development trend and stage focus of the policy, provide support for the construction of research integrity, and provide help for the development of research integrity policy in China. [Method/process] This paper collected 108 policies related to research integrity issued by the central government and ministries, and 80 local policies for the implementation of the central policy.

Finally, this paper got the characteristics of the time of policy release, the characteristics of important institutions, the change of content focus and the characteristics of policy response. [Result/conclusion] ①Relevant governance measures of research integrity have been involved earlier. In recent years, China has put forward the need to build an innovative country, so the number of policy papers has increased sharply, the attitude to the governance of research integrity is more resolute, and the measures are more specific. ②The management of scientific research integrity is led by the central government. The Ministry of Education and the Ministry of Science and Technology are the main administrative departments at all stages. Relevant departments have gradually joined in the joint management. At present, a pattern of joint efforts has been formed. ③There are slight differences in the focus, object and method of research integrity governance among different departments, but generally speaking, the trend is to gradually shift from self-restraint, moral education to system construction and moral construction. ④The vast majority of local provinces and municipalities throughout the country have responded positively to the central policy and taken measures to improve scientific research integrity, but there is a relative time lag.
