Purpose:In recent decades,with the availability of large-scale scientific corpus datasets,difference-in-difference(DID)is increasingly used in the science of science and bibliometrics *** method outputs the unbiased estimation on condition that several hypotheses hold,especially the common trend *** this paper,we gave a systematic demonstration of DID in the science of science,and the potential ways to improve the accuracy of DID ***/methodology/approach:At first,we reviewed the statistical assumptions,the model specification,and the application procedures of DID ***,to improve the necessary assumptions before conducting DID regression and the accuracy of estimation,we introduced some matching techniques serving as the pre-selecting step for DID design by matching control individuals who are equivalent to those treated ones on observational variables before the ***,we performed a case study to estimate the effects of prizewinning on the scientific performance of Nobel laureates,by comparing the yearly citation impact after the prizewinning year between Nobel laureates and their prizewinning-work ***:We introduced the procedures to conduct a DID estimation and demonstrated the effectiveness to use matching method to improve the *** a case study,we found that there are no significant increases in citations for Nobel laureates compared to their prizewinning *** limitations:This study ignored the rigorous mathematical deduction parts of DID,while focused on the practical *** implications:This work gives experimental practice and potential guidelines to use DID method in science of science and bibliometrics ***/value:This study gains insights into the usage of econometric tools in science of science.
