      市场力评估对于确保电力市场公平竞争、提高电力市场运行效率具有重要意义。针对市场力的产生来源和评估方式，按成因将市场力划分为结构性市场力和物理限制性市场力，据此评价国内外市场力评估指标体系的优劣性及适用性，为合理选择实际应用中的评估指标提供参考。将市场力评估方法划分为基于市场份额的评估、考虑负荷及阻塞的评估以及基于参与者系统的评估3类，在此基础上，分析市场力评估研究的发展趋势，为建立健全市场力评估研究提供支持。

英文摘要:

      Market power evaluation in the electricity market is important to ensure fair competition and high market efficiency.In view of the sources and evaluation methods of market power, the source of market power to structural market power（SMP）and physical restrictive market power（PRMP）is attributed. Based on attribution, the advantages and disadvantages of the domestic and international market power evaluation indexes and their application are summarized, reference for reasonable selection of evaluation indicators in practical applications is provided. The assessment methods are divided into three categories：market share - based assessment methods, load and congestion-based assessment methods and participant system-based assessment methods. On this basis, the development trends of market power evaluation research is analyzed to provide support for the establishment and improvement of market power evaluation research.
