Abstract  

[Objective] The article tries to objectively evaluate the influence of China’s webcast Platforms with the help of link analysis. [Methods] First, we used Google search engine and Alexa.com to collect the link data of 20 popular webcast platforms in China. Then, we examined their influence with a modified grey correlation analysis method. [Results] We obtained the ranking of 20 webcast platforms and analyzed their characteristics. [Limitations] We could not obtain comprehensive data from the webcast platforms and the smaple size was limited. [Conclusions] The overall level of current webcast platform is not so good. This article proposes strategies to increase the influence of webcast platforms.
Key words： Link Analysis      Webcast Platform      Grey Relational Analysis      Influence Evaluation
