Abstract: This paper mainly studies on the policy framework of price regulation on power grid. By comparing different regulatory methods and their mixed forms, this paper summarizes regulatory models of major countries in the world into four major models, according to their regulation content and regulation period. Regulatory models of the United Kingdom and the United States are analyzed in detail. Based on theoretical and international practices, this paper points out that the model based on the rate of return regulation implemented in China is suitable for current development period. Subsequent reforms need to develop specific methods to deal with weak incentive caused by rate of return regulation and deviations caused by ex ante pricing. In the end, this paper puts forward two alternative paths for improving incentive effect.

摘要： 本文主要研究电网的价格监管政策框架。通过监管方法配合的视角，以监管内容与监管时间为标准，将世界主要国家的电网监管制度总结为四大模式，并详细对比分析了英美两国的电网监管实践。以理论与国际实践为参照，本文指出我国实行的以回报率监管为基准的模式是适合当前发展阶段的，后续需要针对回报率监管的弱激励以及事前定价的特点，引入强激励机制和不确定调整机制。特别是制定强激励方案，本文提出了两条可选择路径。
