Analysis of Measurement Indicators of Comprehensive Chinese Sci-Tech Core Journals of Preventive Medicine and Public Health from 2012 to 2018

To improve the academic quality and academic influence of comprehensive Chinese sci-tech core journals of preventive medicine and public health, the total core citation frequency, impact factor, annual index, non-self-citing rate, AR paper volume, average number of citations and average number of authors per paper, and funded paper ratio were collected from the 2013—2019 editions of China Science and Technology Journal Citation Report (Core Edition). The linear mixed model was used to analyse the difference and change trend of each index from 2012 to 2018, and the journals were further sorted by the total citation frequency and impact factor. The results indicated that from 2012 to 2018, the number of comprehensive Chinese sci-tech core journals of preventive medicine and public health had increased from 16 to 22, all of which were Chinese journals, including 16 consecutive journals. The impact factor, annual index, AR paper volume, average number of citations and average number of authors per paper showed an upward trend from 2012 to 2018 (P < 0.05); there was no significant difference in the total citation frequency, non-self-citing rate and funded paper ratio among different years (P > 0.05). The academic quality and academic influence of comprehensive Chinese sci-tech core journals of preventive medicine and public health have been continuously improved.
