The performance of Asian S&T journals in international citation indicators

This research explores the performance of Asian S&T journals based on the outcomes of various citation indicators. Indexed by Journal Citation Reports - Science Citation Index Expanded (JCR-SCIE), journals published in China, Japan, India, Singapore, South Korea, and Taiwan between the years 2008 and 2012 are collected and analysed using bibliometrics and statistics methods. Results showed that the mean impact factor (IF) value of the journals from all countries was less than 1.3 throughout the period. Only journals from China and Japan had a mean IF or 5-year IF (5Y-IF) value exceeding 1. The self-cited rate of the journals from South Korea remained the highest among selected countries but showed a declining trend every year. The self cited rates among journals from all the six Asian countries did not considerably affect the journals' IF values. The results revealed that the IF-based ranking factor (IF-RF) of Chinese and Japanese journals in various subject fields constantly improved from 2008 to 2012, but this improvement trend was not observed in journals from the other four countries. Overall, the journals from Japan and China demonstrated stronger impacts than those from the other countries.
