| 摘要: |
| 可再生能源配额制（RPS）要求可再生能源在电力生产中占有一定比例，但实施过程中出现的市场力问题会对可再生能源证书（REC）市场和电能市场带来影响。针对RPS实施中的市场力问题，提出了主导企业竞争边缘模型，分析了不同主导企业的市场力对REC价格和上网电价的影响。在不同RPS要求下，通过实证研究得出不同主导企业的市场力对REC价格和上网电价的影响结果,说明REC价格太低将导致长期可再生能源发展的投资不足，REC价格太高也会扭曲投资的激励信号，导致长期发电资源的低效配置。因此，管制机构需要认真监督市场绩效，从而保障在RPS政策体制下可再生能源的健康发展。 |

| Abstract: |
| Renewable Portfolio Standard (RPS) requires a certain percentage of electricity production from renewable. The market power in the process of RPS implementation always affects the renewable energy certificate/credit (REC) market and electricity market. This paper develops dominant firm-competitive fringe models that account for market power. It shows that market power could have significant impacts on the REC and power prices. Through empirical research, this paper gets the effects of market power on REC and power prices with different RPS requirements increase in different dominant firm situation. This paper indicates that lower REC price could lead to an underinvestment in renewable in the long run. Meanwhile, higher REC price could distort investment incentives, resulting in inefficient resource allocation for power generation in the long run. Therefore, regulatory agencies need to carefully oversee the market performance to ensure a healthy development of renewable industries under the RPS policies. |
