为了准确判断中外媒体在海外社交网络平台上的国际传播效果，本文对2017年Twitter、Facebook和YouTube这三大海外社交网站的传播情况进行了三个阶段的评估：一是评估8家中国主流媒体账号的全年传播情况，二是将中国媒体账号与40家国外知名媒体账号的传播情况进行横向对比，三是对热门帖文、热门视频、热门词汇、热门标签进行深度剖析。基于评估的结果，对中国媒体在海外社交网络平台上的传播提出了有针对性的策略建议。
To accurately size up the international communications effect of Chinese and foreign media on overseas social networks，this paper evaluates the effect of communications on three major overseas social networks：Twitter，Facebook and YouTube，in three stages. One is a year’s communications by eight Chinese mainstream media accounts；another is the horizontal comparison between the Chinese media and 40 well-known foreign media accounts；and the other is an in-depth analysis of the hot posts，hot videos，hot words and hashtags. Based on the evaluation results，the paper tries to put forward some well-targeted proposals for Chinese media in their communications activities on overseas social network platforms.
