摘要：A discrete-time financial system is proposed by using forward Euler scheme. Based on
explicit Neimark-Sacker bifurcation (also called Hopf bifurcation for map) criterion, normal
form method and center manifold theory, the system's existence, stability and direction of
Neimark-Sacker bifurcation are studied. Numerical simulations are employed to validate the
main results of this work. Some comparison of bifurcation between the discrete-time financial
system and its continuous-time system is given.
