Evaluation and comparison of influence in international Open Access journals between China and USA

This paper makes an evaluation and comparison of influence on international Open Access (OA) between China and USA. First, Chinese and American OA journals are taken as an example. Second, combining traditional citation indicators with altmetrics indicators, a process of influence evaluation and comparison model on Chinese and American OA journals is constructed. Third, an evaluation indicator system of OA journals from two dimensions of academic influence and societal influence is constructed too. Lastly, through normalization, correlation analysis, reliability analysis, validity analysis, factor analysis and two-dimensional analysis, the academic and societal influence of OA journals are evaluated and compared between China and USA. It is found that in terms of academic influence and societal influence, the evaluation scores of international OA journals are quite different between China and USA. The influence of the USA is far greater than that of China. The results show a strong positive correlation among the 7 traditional citation indicators based on JCR, and a high positive correlation among the 8 altmetrics indicators based on Altmetrics Explorer, and the indicators have a significant consistency both overall and internal. There is a highly positive correlation between academic influence and societal influence scores for the Chinese and American OA journals. Overall, the results confirm that the evaluation of societal influence of OA journals is used as supplement to the evaluation of academic influence. Altmetrics is also a powerful tool to measure the societal influence of OA journals, but it cannot replace the traditional citation indicators at present.
