摘　　要：从信息范式的角度,讨论电力市场的运行模式。在假定市场信息不完备或不对称条件的前提下,探寻追求效用最大化的理性个体之间博弈行为的本质。在不改变最大化行为的前提下,将信息不对称或不完备的假设应用于均衡分析,通过边际分析和演进的均衡分析方法,深入研究电力市场交易的内部关联。对发电商的微观行为进行分析,证明了市场的信息结构,对发电商报价策略的选择和市场力的发挥都起着重要的作用。The operation mode of the electricity market is studied from the view of information paradigm in this paper. And the essential problem of the game action between the individuals searching for utility maximization is discussed under the condition of imperfect and asymmetric market information. Under the precondition of not changing the maximization action ,it is helpful for the study of the internal relationships of electricity market trade to apply the hypothesis of information asymmetry and imperfection into the equilibrium analysis. The information structure of the electricity market is very important for the generation companies to choose the pricing strategy and exert the market power.
