摘　　要：构建了市场条件下电煤价格竞争的博弈模型。该模型分为两层,第一层发电商根据煤炭企业和运输公司的报价进行最优购煤决策,第二层煤炭企业和运输公司依据发电商的决策模型选择最优的报价策略,通过求解KKT条件将两层优化模型融合为一层模型,求解Nash均衡得到模型的最优解。The game model of the price competition between the electricity and the coal was built.The model was divided into two layers.In the first layer,the generation companies make the optimum coal purchasing decisions according to the quotation of the coal enterprises and the transportation companies.In the second layer,the coal enterprises and the transportation companies choose the optimum quotation strategy according to the decision of the generation companies.The two-layer optimal model was integrated into a one-layer model by solving the KKT condition,and the optimum solution of the model was obtained by solving the Nash equilibrium.

关 键 词：电煤价格 KKT条件 NASH均衡
