以新浪微博平台的中国媒体智库及其主办媒体为主要分析对象，以各个机构间的关注关系构建社会网络，探讨媒体智库微博传播生态的社会网络结构和特征，并以社交网络影响力大的媒体智库——国是直通车为案例，结合数据挖掘的方法探究提升社交网络影响力的策略。研究发现：中国媒体智库社交媒体传播生态呈现以主办媒体为核心，以媒体智库为边缘的结构，且存在媒体智库社交网络影响力不足、“马太效应”显著、媒体间智库相互独立为“信息孤岛”的问题。最后，提出了提高媒体智库社交网络影响力、深化“媒体+智库”合作模式、打破媒体智库间“信息壁垒”的建设性建议。

We focus our research on Chinese media think tanks and their host media on Sina Micro-blog. We use social network analysis method to construct a social network according to the "follow" relationship between various institutions, so as to discuss the social network structure and characteristics of the communication ecology of media think tanks on Micro-blog. Taking the media think tank"Guoshi Zhitongche", a social network with great influence, as a case, this paper explores strategies to improve the influence of social network by combining data mining methods. The research finds that the social media communication ecology of Chinese media think tanks presents a structure with the host media as the core and the media think tank as the periphery. The existing problems are as follows: media think tanks lack influence on social networks, "Matthew effect" is significant, and media think tanks are independent of each other as "information islands". Therefore, we put forward constructive suggestions, such as improving the social network influence of media think tanks, deepening the "media + think tank" cooperation mode, and breaking the "information barrier" between media think tanks.
