摘要 有关电力市场改革中竞争性的讨论已暴露出对市场权力的定义、分析、实质有很多误解,本文试图阐明市场权力的内涵以及如何将市场中竞争性定价和重要的短期供给约束区别开。同时也提出市场权力的两种常用说法:(A) 市场权力存在于所有市场中;(B) 市场权力的存在必须使公司收回固定成本后还能盈利。通过讨论得出:市场中存在市场权力并不必然预示需要政府的干预;分析市场权力对建立公平的政策有很重要的意义。 Discussions of competition in restructured electricity markets have revealed many misunderstandings about the definition, diagnosis, and implications of market power. In this paper, I attempt to clarify the meaning of market power and show how it can be distinguished form competitive pricing in markets with significant short-run supply constraints. I also address two common myths about market power: (A) that it is present in all markets and (B) that it must be present in order for firms to remain profitable in markets with significant fixed costs. I conclude by arguing that,while a finding of market power in an industry does not necessarily indicate that government intervention is warranted, such analysis is an important part of creating sound public policy.
