Abstract:

[Purposes] The study aims to compare the time sequences between research hotspots appearing in scientific journals and hotspots appearing on the internet, and discuss the development path of scientific journals from the perspective of communication content. [Methods] Bibilometrics and webometrics were used to analyze the research hotspots of Chinese Journal of Health Policy from 2011 to 2016, and the Baidu Index was used to describe the trend of network attentions for high-frequency keywords in scientific journals. [Findings] Fourteen high-frequency keywords in top-five per year are extracted from Chinese Journal of Health Policy from 2011 to 2016. The appearing time of most high-frequency keywords in scientific journals is earlier than the time when the peak appears on network media, while the others are in the same period. [Conclusions] The professional hotspots can be found earlier in scientific journals than that on network media. Improving the communication content and ensuring the leading role of research hotspots are the key measures on increasing the journal competiveness.
