摘要
利用1987-1999年经济合作与发展组织(OECD)成员国的面板数据1,重新审视电力体制改革对电价的影响,并且把结果与一份关于电力体制、结构及市场运行状况的早期研究进行比较。结果与预期相同:零售侧引入市场机制的扩大化可能降低电价,并加大工业用户与居民用户的电价差别。但发输电分离和即时批发市场并不一定会降低电价,而且可能会导致更高的电价。这个发现不同于一般的预测,但从最近许多国家的经验看,这个发现似乎是可信的。
The impact of electrict industry regulatory reforms on prices is reexamined by using me panel oata for l OECD countries of the period 1987-1999. The results are compared with those found in an earlier study in 2000. It can be found that expanded retail access is likely to lower the industry prices and increase the price differential between industry customers and household customers. But the unbundling of generation and the introduction of a wholesale spot market do not necessarily lower the price and may possibly result in a higher price, This finding is not consistent with expectations. But it is plausible according to recent experiences in many countries.
