Abstract:International think tank evaluation mainly includes market-led evaluation model, government-led evaluation model and third-party-led evaluation model. The US think tank is market driven. South Korea think tank is dominated by the government. The German think tank evaluation mainly adopts the mode of the third party organization commissioned by the government. Based on the research of the evaluation process and characteristics of think tanks in the United States, Korea and Germany, this paper puts forward some countermeasures and suggestions on the establishment of evaluation model, evaluation method and evaluation index system of think tanks that meet the development needs of science and technology think tanks in China.
