Figure 3

Simulation visualization for evolution of investor’s trading behavior in four network (ER Network, WS Network, BA Network, and IN Network), with the change of neighboring preferred degree, at different network degree (⟨𝑘⟩=4 and ⟨𝑘⟩=12), on the condition of peer effect function’s being marginal utility decreasing.
