电力市场效率理论及其评价方法

电力市场效率研究是电力市场建设的核心问题。文章提出了考虑宏观因素、市场内部因素、物理因素的广义电力市场效率理论，从电力市场效益、交易成本、外部性、市场力、风险等方面详细论述了产权制度、政府职能、法律保障、市场机制、市场结构、交易品种、交易方式、电网结构等因素对电力市场效率的影响，提出了基于资源配置状态、生产者和消费者剩余及其增量的电力市场效率评估关键指标，从不同层面有效评估了电力市场效率。

Efficiency Theory of Electricity Market and Its Evaluation Method

Making clear efficiency of the electricity market is the core issue of electricity market construction. In this paper, a generalized efficiency theory of electricity market, in which the macroscopic factors, the internal and external factors as well as physical factors of market are taken into account, is proposed. In the field of the benefit of electricity market, cost of transaction, market externality, market power and risk, the impacts of such factors as property right system, government function, legal guarantee, market mechanism, market structure, trade variety, transaction mode and power network structure are studied on the efficiency of electricity market; based on the resource allocation condition, producer- and consumer-surplus and their increments, the key indices to evaluate electricity market efficiency are put forward, thus the efficiency of electricity market can be effectively evaluated in different aspects.
