Abstract：We build an interbank network model based on risk-averse behaviors. On a heterogeneous network structure, we explore the relationship between risk-averse behaviors of banks and systemic risk contagion, specifically, liquidity hoarding, fire sales behaviors and the composition of risk-averse behaviors. The simulation results show that liquidity hoarding behaviors mitigate systemic risk contagion at early stage, fire sales behaviors have little effect on mitigating systemic risk contagion and the composition of risk-averse behaviors exacerbate the systemic risk contagion. Heterogeneous network is more robust than the homogenous network if risk-averse behaviors exist, otherwise the homogeneous network is more stable. Furthermore, bank asset heterogeneity has no significant effect on systemic risk contagion.
