摘　　要：传统的电力市场结构分析基于狭义的市场效率概念,对区域统一市场和区域共同市场这2种市场结构的比较存在局限。根据制度经济学中制度外部性和交易成本的关键思想,定义了电力市场中社会总效率的概念,提出了基于社会总效率的电力市场结构分析方法。应用该方法,研究了电力市场外部性的2种主要表现形式:扩大地区间经济发展不平衡性和提高整体电价水平,分析了交易成本和安全风险对电力市场的影响,比较了区域统一市场和区域共同市场在市场效率、市场外部性和交易成本等方面的优劣。两者社会总效率的综合比较表明:在我国当前省间经济发展和电价水平存在较大差距的实际情况下,区域共同市场比区域统一市场具有更高的社会总效率,是更适合我国国情的区域电力市场结构。Conventional structure analysis of electricity market is based on the narrow market efficiency ,with some limitations in the comparison of platform between regional uniform market and regional layered market. According to system externality and transaction cost of institutional economics,the social total efficiency is defined and the extended electricity market structure analysis method is established based on it. Two forms of electricity market externality are studied respectively：enlarging the unbalance of interregional economic development and raising the level of electricity price. The effects of transaction cost and security risk on electricity market are also analyzed. The market efficiency,market externality and transaction cost are compared between regional uniform market platform and regional layered market platform. The comprehensive comparison of social total efficiency between them indicates that,as there are great differences in economic development and electrical price between provinces,regional layered market platform has more social total efficiency than regional uniform market platform,and is more suitable for China.
