At present, the issue of scientific research integrity has become a hot issue of common concern to academia and the public, and scientific research personnel' research misconduct has always been the focus prevention area of scientific research integrity, so it is the key to prevent and curb breach of trust from the source. This study conducts semi-structured interviews with 26 scientific researchers, uses rooted theories to encode the original data, and constructs an analysis framework for theinfluencing factors of scientific research credibility from four dimensions: scientific research literacy, personal literacy, resource environment and institutional policies. Research shows that the personal accomplishment and scientific research literacy of scientific researchers are internal driving factors that directly determine the frequency and intensity of their scientific research dishonesty behaviour. The resource environment and system policy are external driving factors that indirectly affect the scientific research credibility of scientific researchers. The research results provide countermeasures and ideas for further standardising the behaviour of scientific researchers and creating a healthy academic environment.
