The aim of this research is to explore journal self-citation, as well as its impact on the outcomes of frequently used
major citation analysis indicators. Journals published in China, Japan, India, Singapore, South Korea, and Taiwan,
during 2010 to 2012 and indexed by JCR-SE are collected and analyzed using citation analysis and statistics
methods. The results show that Japan had the highest number of journals indexed in JCR-SE, and also had highest
average IF values. Six countries had average self-citation rates mostly below 23%. The self-citation rates of Japan
and Singapore are relatively stable, with the lowest values and the least variations. In general, self-citations show
no significant effect on corresponding IF values in all countries.
