Abstract: In view of the current situation and problems in the construction of new think-tanks with Chinese characteristics, based on clarifying the operation logic of think-tanks in national decision-making, this paper discusses the connotation, necessity and innovation strategy of the operating mechanism of the "revolving door" for the think-tanks. Chinese think-tanks have a "revolving door" mechanism with the characteristics of localized operation. The "revolving door" channels of the official think-tanks are relatively smooth; those of social think-tanks "revolving door" channels are slightly narrow; those of local think-tanks between CPC and government departments are not smooth. The "one-way rotation" exists between government officials and think-tank experts. The "revolving door" mechanism is helpful for new think-tanks to acquire data and information, build a smooth channels of advice and to invigorate the talent resources. In order to promote the transformation of the achievements of new think-tanks to public decision-making, it has suggested that the government and think-tanks should be reformed in aspects of two-way personnel flow, talent evaluation, temporary training.
