In order to explore the influence of data literacy on scientific research performance,this paper designs a data literacy evaluation scale from dimensions of data awareness,data acquisition ability,processing capacity,analysis and utilization ability and data ethics. The paper measures the performance of scientific research from the number and quality of research papers,inventions,patents,research projects and scientific research awards,and constructs the influence model of data literacy on research performance. Through the test of Cronbach's α coefficient,results show that the scale has good reliability and validity. Data acquisition ability,data analysis and utilization ability,and data ethics positively affect the scientific research performance,while data awareness and data processing ability have no significant effect on the scientific research performance.
