Abstract:

A total of 26 material sciences journals in the 2019 Annual Report for Chinese

Academic Journal Impact Factors published by CNKI were quantitative studied. The characteristics

of on-line first material sciences journals on database platforms at home and abroad were studied

through horizontal comparison. The correlation mechanism between on-line first and influence

index was analyzed through vertical comparison within the discipline. The proportion of on-line

first of material sciences journals is 58%. The horizontal comparison shows that the proportion and

efficiency of on-line first in English journals are significantly higher than those in Chinese journals，

and each of the on-line first papers in English journals are marked with a Digital Object Unique

Identifier（DOI）which is resolved. The longitudinal comparison results show that the impact

factors of the 14 on-line first journals have shown an upward trend in the last three years. The

contribution of on-line first to the frequency of download has a significant effect. Scientific journals

in material sciences with high IFs pay more attention to on-line first. The on-line first of domestic

material sciences journals needs to be further promoted.
