The monopoly of our country stems from the planned economy and it has changed to some extent after the reform and the opening- up policy，but the administrative monopoly still occupies the leading position.In view of our country's conditions，some of the existence of the administrative monopoly are rational and the other are unreasonable.Reasonable administrative monopoly and economic monopoly can be called the normal monopoly，while the unreasonable administrative monopoly can be called the abnormal monopoly.The abnormal monopoly destroys the rational resource distribution and damages the social economic welfare.So the spearhead of anti-monopoly should be mainly pointed to the abnormal monopoly in our country.
