The invention relates to stem cell differentiation technology in the technical field of stem cell treatment and in particular relates to a method for inducing differentiation of neural stem cells (NSCs) into dopaminergic neurons. The method is characterized by culturing 1-2 generation NSCs from the forebrain with a NSC basal culture medium until the diameters of neural spheres are 0.5-1mm, then changing the culture medium to an induction culture medium to enable the cells to grow adhering to the wall and obtaining dopaminergic neurons after culture for 3-10 days, wherein the induction culture medium contains inducers aFGF, TPA, forskolin, pramipexole and BMP-7. The method has the beneficial effects that after the NSCs from the forebrain are cultured by utilizing the induction culture medium, the proportion of the dopaminergic neurons obtained through differentiation of the NSCs is 30%, thus greatly increasing the differentiation rates of the dopaminergic neurons; the dopamine secretion rates of the neurons are increased by more than 20 times; the NSCs from the forebrain are effectively induced into the dopaminergic neurons.
