摘　　要：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。Relying on before - and - after deregulation data collected from 309 power plants nationwide, this paper makes use of difference - in- differences model to investigate into the deregulation policy results between 2002 and 2005 from an empirical perspective. As the empirical test results shows, the deregulation policy in the generation side didn＇ t increase resource allocation efficiency and productivity significantly. Deregulation incompleteness brought about distortion in generationside market competition; and as it can been observed, deregulation is neg- atively correlated with the relative productivity and electricity- generation efficiency.
