Evolutionary game analysis and computer simulation of iron ore price negotiation

摘要

The paper established an evolutionary game to analyze the international iron ore price negotiations which the Chinese steel enterprises participated under the rationality assumptions of negotiation parties. The results showed that the interest improved in the price negotiations between the steel enterprises and the iron ore enterprises is related to the additional income from both the steel enterprises and iron ore enterprises compromise, and the betrayal revenue for the party who choose the non-compromise strategy while the other party select the compromise strategy. Next, we simulate the evolutionary game using the matlab7.10 and find that the larger the distribution coefficient of additional income of the steel enterprise or the iron ore enterprises is, the faster the enterprise chooses the compromise strategy. Finally, we suggest some reasonable iron ore negotiation strategies to provide Chinese steel enterprises with a theoretical basis.
