摘要
基于信息经济学和制度经济学的信息有效市场理论,从电力市场中信息披露有效性的全新角度,分析了信息披露对市场效率、交易成本、交易速度和市场公平性的影响;根据信息披露的主体和有效性原则,设计了电力市场信息披露有效性的评价指标;应用这些评价指标,分析比较了电力市场中双边交易和集中交易2种主要的交易方式的特点和适用环境;在借鉴国外电力市场建设经验的基础上,从信息披露有效性的角度分析了华东和东北区域电力市场的交易方式设计;提出了中国应根据国情、市场环境和交易目标,采用以中长期双边交易为主、现货集中交易为辅的市场模式。
Based on the efficient market theory in information economics and institutional economics, information disclosure and its effects on market efficiency, transaction cost, transaction velocity and market fairness are analyzed, from the new view of information disclosure effectiveness. Then the evaluation indicator system of electricity market information disclosure is established according to the subjects and principles of information disclosure. Applying this evaluation indicator system, characteristics and suitable environments of two main transaction modes, i.e. bilateral trading and centralized trading are compared. The conclusion is that the mid-long term bilateral trading should be the chief transaction mode, and spot centralized trading the assisted one according to national conditions, actual market environment and transaction target in China.
