During the process of Centralized Public Bidding in drug purchasing in China，some achievements of the six policy objectives have been made along with the emergency of new problem；however，the achievement is gratifying to us. The direct cause lies in defects of the policy design and imperfect implementation，which come from the incomplete institutions. Reforms of Centralized Public Bidding in drug purchasing should be pushed at two stages，i.e.，the short term and the medium and long term. In short term，the objective of bidding policy must be defined rationally at first. The public drug bidding should be continued centrally by local government，and the government-affiliated agency should be encouraged to procure the National Essential Drug. In medium and long-term，the National Essential Drug should be procured by the government，and Non-National Essential Drug should be procured by the hospitals or other Non-Government Organizations. The government should play a much important role in the bidding rule making，public information service，and supervising on process of drug procurement.
