Legal education plays an important role in cultivating the subjective elements of new quality productivity. This paper mainly uses two-way fixed effect model, individual effect and time effect, to empirically study the influence effect of legal education on the new quality productivity and its functioning mechanism, and to reasonably explain the empirical results in line with the logic of reality. Secondly, from the perspective of talent aggregation effect and talent ecological environment, the qualitative comparative analysis method of fuzzy set (fsQCA) was chosen to analyze the development path of legal talent-driven new quality productivity. It is found that no matter which fixed effect model, it can be obtained that the average increase of legal education index by 1%, the index of new quality productivity increases by about 21.3%, the effect of legal education on the development of new quality productivity is significant, and the effect of legal education empowering the development of new quality productivity is positive. Legal talent concentration and the talent ecosystem have positive feedback effects on the development of new industries.
