Abstract:In order to measure the influence of state key laboratories in the new era, the online media influence evaluation system is constructed to analyze the influence of the online media influence of the state key laboratories. This paper uses the AHP to construct the online media influence evaluation system of the state key laboratory, and calculates the corresponding weight coefficient. At the same time, 156 state key laboratories are selected for case study. The results show that the influence of online media among state key laboratories is uneven, and most of them are in sync with the influence level of third-party platforms; the state key laboratories have great influence on the use of independent platforms, especially WeChat and Official website. Based on this, it is recommended that state key laboratory actively establish contacts with various social media, strengthen the content construction of the WeChat public account, and strengthen suggestions for the construction and maintenance of the official website.
