Abstract:In the way of analyzing the article count, fractional count and weighted fractional count from the nature index, taking the example of China, India, Japan, South Korea and Singapore, we compare the ability, advantaging subjects, efficiency of the high-quality research and the international collaboration, indicating that China has a much better high-quality research than the other Asia Pacific countries, but has a relatively lower research efficient and out-of-balance subject development. China, Japan and Australia are the main outer collaborating countries with each other.
