Abstract: We solve the problem on local statistics of finite Lyapunov exponents for M products of  NXN Gaussian random matrices as both M and N go to infinity, proposed by Akemann, Burda, Kieburg and Deift. When the ratio  (M+1)/N changes from 0 to  infinity , we prove that the local statistics undergoes a transition from GUE to Gaussian. Especially at the critical scaling  (M+1)/N /to /gamma /in (0,/infty)， we observe a phase transition phenomenon.
