Abstract In this paper, we study the evolution of global cooperation through proposing a multilevel threshold public goods game model, and introducing an insurance compensation mechanism to probe the risk control. We find that high risk and high threshold are in favor of global cooperation. Furthermore, the introduction of insurance compensation remarkably promotes the emergency of global cooperative behaviors. On the other hand, the fixation time of global cooperation is sharply shortened after introducing insurance compensation mechanism. Besides, global cooperation is strengthened with the increase of imitation intensities.
