摘要
采用DEA方法的CCR模型和超效率模型,比较了美国PJM市场在有竞争市场的情况与假定无竞争市场情况下的发电厂效率,并通过投入冗余度来衡量影响发电厂效率的资源配置是否合理。根据计算结果来科学、客观地评估电力改革所带来的影响并分析原因,从而概括出PJM市场对我国电力工业改革的启示。
This paper selects some models that are appropriate for the evaluation of power plant, such as technology efficiency model （CCR） and super efficiency model and compares the power plant efficiency in electric market with competition to without competition. It also introduces the input redundancy rate to find out weather the resources allocation is reasonable. According to these evaluations, we can assess the affection of electric power restructure objectively and scientifically and analyse the reason to find out the enlightening to power electric industry in China.
