摘要
Aiming at the problem in supervision of dangerous chemicals in ports, this paper establishes an evolutionary game model between government regulators and accident rate. A replicator dynamic equation is established to depict the evolutional behavior of government and enterprise during supervision of hazardous chemicals in ports. An evolutionary numerical simulation is carried out. The "paradox of supervision" exists in the supervision of hazardous chemicals in ports. In the short term, enterprises tend to choose the safety strategy for facilities to cope with the strict supervision of the government. In the long run, enterprises cannot consciously choose the safety strategy for facilities. The choice of enterprise strategy is not affected by the enterprise income but is related to the probability of accidents. In the face of low risk, regardless of whether government regulations are strict or not, enterprises choose to ignore risks. In the face of high risk, the government does not take strict supervision, and enterprises will consciously choose safety strategy for facilities. © 2019, Editorial Department of Journal of HEU.
