Abstract: Scientific paradigm evolution is the core issue of scientific development, while tacit knowledge continues to accumulate in the academic genealogy, and its inheritance is crucial to scientific paradigm shaping. Focusing on the mechanism of the role of tacit knowledge transformation in the transmission of academic genealogy on the formation of scientific paradigm, 967 valid samples were collected through questionnaires and empirically examined using structural equation modeling. The study shows that tacit knowledge transformation significantly contributes to scientific consensus through cognitive consensus, methodological consensus, normative consensus, etc., and then promotes the shaping of disciplinary characteristics and the formation of scientific paradigms; disciplinary attributes play a moderating role in this process; the higher the maturity of the discipline, the stronger the cross-fertilization, and the greater the degree of openness and tolerance, the higher the marginal utility of tacit knowledge transformation, and the greater the likelihood of the formation of innovative scientific paradigms. The higher the maturity of the discipline, the stronger the cross-fertilization and the greater the openness and tolerance, the higher the marginal utility of tacit knowledge transformation and the greater the possibility of innovative scientific paradigm formation. The study deepens the theoretical connotation of academic genealogy and expands the path of analyzing the cross-level influence mechanism of tacit knowledge, which is inspirational for government departments to formulate policies on talent cultivation and discipline construction, for universities and research institutions to improve academic management and promote scientific research innovations, and for scholars to pursue excellence in innovations and expand the paths of their academic careers.
