Abstract：Objective To create a good social atmosphere, put an end to the phenomenon of accepting kickbacks, standardize the
process of medical equipment market, optimize the supervision mechanism of public hospital medical equipment bidding and
purchase. Methods Based on evolutionary game theory, stakeholders in the stage of medical equipment bidding and procurement
were identified, an evolutionary game model was constructed. The evolutionary strategy of behavior selection of all parties was
obtained by solving the model, and the influence on the behavior of participants was discussed by using Matlab
simulation. Results According to the model analysis, a good equilibrium state could be achieved when the extra income of
collusion was less than the sum of the punishment and cost of collusion investigated and punished, and the cost of strict supervision
by regulators was small. Conclusion Through the model simulation analysis, it is found that only strengthening the supervision of
one party can not achieve the supervision goal, strengthening the supervision and punishment of the conspirators can prevent the
occurrence of corruption collusion, and the audit institutions’ excessive accountability for the supervision machine is not conducive
to the transformation of the strategic behavior of both parties to the ideal balance state.
