Some significative conclusions are founded out in the dissertation. The evolution of securities investor behaviors bears multi-equilibrium characteristics, namely, possibly converging to the equilibrium of complete value investment, or full noise trade, or coexistence of former two behaviors. And its evolution path and equilibrium are affected not only investor's payoff function and initial state of securities market, but expect error of noise traders, noise trade risk and so on.
