In view of the cross-field and cross-discipline characteristics of science popularization and the extensive influence of decision making, the basic elements of the orientation and connotation of think tank for popularization of science were put forward. According to the requirement that the science popularization and science and technology innovation are equally important,the human resource, the products and the evaluation of think tank for popularization of science were analyzed. The paper put forward that the research and thinking on the theoretical and practical problems related to the think tank for popularization of science should be accelerated. Think tank for popularization of science should carry out forward-looking, long-term and stable research on the overall problems and major problems of the development of science popularization and the demand of science popularization industry in China, so as to promote the high-quality development of science popularization in China.
