市场力对发电公司收益的影响研究

Research on the effect of market power on generation companies

利用产业经济学的新经验主义产业组织学引入推测变分对发电公司的市场行为进行分析,并定量评估电力市场环境下发电公司所拥有的市场力,论述了市场力的运用,推测变分的设定与发电公司的收益之间的关系。研究表明,发电厂商为了获取高额利润会通过设定自己的推测变分来调整市场力,只要推测变分设定适当,无论成本高低,发电公司都可以获取高额利润。

Market behaviors of generation companies are analyzed by using New Empiricism Industrial Organization and the conjectural variations of generation companies are introduced. After estimating the market power of generation companies in the electricity market environment, the relationship between market power and profit of generation companies is discussed by setting the conjectural variation. It is indicated that in order to acquire high interests generation companies set their own conjectural variations to adjust their market power. As long as the conjectural variation is appropriate, generation companies can acquire high interests, no matter whether the costs are high or low.
