通过政府规制下各国发电市场结构演进实践的考察和分析,认为政府利用准入规制控制了发电市场主体进入市场,是政府对发电市场结构进行规制的主要手段,决定着竞争性发电市场结构的形成;政府对市场力的规制可以防止发电商滥用市场力逐利,损害竞争,导致社会福利无谓损失,保护着竞争性发电市场结构形成。结论是政府规制对发电市场结构的演进起着决定性作用。 Through the investigation and analysis of the evolvement of the power generation market structure in various countries under the government regulation, it is considered that the government controls the entry of the main power generation market into the market, which is the main means by which the government regulates the structure of the power generation market and determines the formation of competitive power generation market structure ; The government’s regulation of market power can prevent power producers from abusing market power for profit and damaging competition, leading to unnecessary loss of social welfare and protecting the formation of competitive power generation market structure. The conclusion is that government regulation plays a decisive role in the evolution of power market structure.
