选取全国范围内309家发电厂放松规制前后的生产经济数据,使用双重差分模型对2002年至2005年放松规制的政策效果进行了实证检验和研究。结果表明,发电侧放松规制政策未能显著提高我国电力行业发电厂的资源配置效率和生产效率,放松规制政策的不完全性导致发电侧电力市场的竞争发生扭曲。因此,应进一步完善电力市场的竞争结构,使信息披露机制更加透明化。
Select 309 national power plants before and after relaxation of the regulation of production and economic data, the use of double-difference model to relax the regulatory policy from 2002 to 2005 conducted an empirical test and study. The results show that the relaxation regulation policy of generation side can not significantly improve the resource allocation efficiency and production efficiency of power plants in our country, and the incompleteness of regulation policy loosens the competition of power generation side power market. Therefore, the competition structure of the power market should be further improved to make the information disclosure mechanism more transparent.
