【目的】对比分析科技期刊研究热点与网络关注峰值出现的时间顺序,从传播内容角度探讨科技期刊发展途径。【方法】采用文献计量学和网络计量学方法,分析2011—2016年《中国卫生政策研究》的研究热点,并以百度指数为测量指标,统计相应高频关键词的网络关注程度。【结果】2011—2016年《中国卫生政策研究》各年度前5位的高频关键词共有14个,其中多数期刊高频关键词的出现时间比网络关注峰值出现的时间早,少数期刊高频关键词的出现时间与网络关注峰值的出现时间一致。【结论】与网络媒体相比,科技期刊可以更早地发现专业热点问题,而改善传播内容、保障引领地位是提升科技期刊竞争力的关键措施。
【Objective】 The purpose of this paper is to compare and analyze the time sequence of the hot spots in the research of sci-tech periodicals and the peak of the network attention, and to explore the ways of sci-tech periodicals development from the angle of dissemination. 【Method】 By using bibliometrics and econometrics methods, this paper analyzes the research hotspots of “China’s Health Policy Research” from 2011 to 2016. Using the Baidu index as the measurement index, the network attention of the corresponding high-frequency keywords is calculated. 【Results】 There were 14 high-frequency keywords in the first five years of “China’s Health Policy Research” from 2011 to 2016. Most of the high-frequency keywords in most journals appeared earlier than the peak of network attention. The appearance time of the key words coincides with the appearing time of the peak value of the network concerned. [Conclusion] Compared with the online media, the sci-tech periodicals can find the hot issues of the specialty earlier, and improving the dissemination content and guaranteeing the leading position are the key measures to improve the competitiveness of sci-tech periodicals.
