Abstract: 【Purpose/significance】The scientific research integrity policy is an important carrier for the government to manage scientif⁃ic research integrity issues,and its evolution characteristics show the development history of the research integrity problems in China.In recent years,dishonesty in scientific research has emerged one after another in China.In-depth analysis of the development of scien⁃tific research integrity policy is conducive to summarizing experience and provides references for the formulation of scientific research integrity policy in China in the future.【Method/process】This paper selects 75 scientific research integrity policy texts issued by the Chinese government from 1981 to 2020,analyze and summarize the development trend of scientific research integrity policies through in-depth analysis of the policy texts【. Result/conclusion】The development of China's scientific research integrity policy can be divid⁃
ed into four stages: the germination period (1981-1999); The initial development period (2000-2006), the rapid development period (2007-2016) and the new development period (2017 year to date) of the scientific research integrity policy; the development of China's scientific research integrity policy is becoming more and more targeted and nuanced; the strength of China's scientific research integri⁃ty policy has formed a complete system; the concept of scientific research integrity has gradually become clear,but there is still not clearly defined; China's scientific research integrity policies focus on restraining individuals and dealing with academic misconduct, but pay little attention to the evaluation; the cooperation of China's scientific research integrity policy release departments needs to be
strengthened【. Innovation/limitation】The paper summarizes the changing process and evolution characteristics of China's scientific re⁃search credit policies from the new perspectives,and then evaluates China's scientific research credit policies and puts forward some suggestions.
