| 摘 要： | 价格上限是电力市场化改革的简单产物。事实上价格上限不能有效地抑制电价飞升和规避市场风险。作者首次将最高限价同动态调整机制联系起来，提出了利润上限模型。该模型吸取了英国的零售价格指数法(RPI-X)和美国的回报率法(ROR)两种监管思想，克服了价格上限在吸引投资和规避风险方面的两难选择，矫正了边际成本定价造成的利润剧烈波动，为发电侧市场的最高限价监管提供了一套可行的解决方案。

| Abstract: | Price cap is a natural by-product of power industry restructuring. In fact, price capping cannot suppress the price spikes and evade the market risks effectively. For the first time the price limit is integrated with dynamic profit-adjusting mechanism, and a new regulation model, namely Profit Capping Model (PCM), is proposed. The PCM assimilates the essence of two popular regulation tools, i.e., the British Retail Price Index (RPI) and the American Rate of Return (ROR). By means of PCM, the dilemma in attracting investment and evading risk is overcome. The profit fluctuation caused by marginal-cost-pricing is remedied. It can be proved that the PCM is a successful and practicable solution to the deregulated electricity market. |
