Abstract:In the network environment, it is very important to evaluate the network influence of think tanks. The paper constructed the evaluation index system of the network influence of think tanks, which was composed of three first-level indicators (think-tank website construction, think tank network communication, and new media of think tank) and seven second-level indicators. Based on the analysis of data from the top 10 universities, the Party, Government and Army, the local academy of social sciences and the social think tanks in "China Think Tank Report 2015", we found that network influence of university think tanks was far ahead; the Party, Government and Army think tanks performed well in network influence; social think tanks were leading in the new media influence; the local academy of social sciences think tanks' network influence was the lowest. Finally, the paper put forward four suggestions including focusing on website construction, flexible use of new media, enriching participation forms in network and strengthening cooperation with media.
