The number of published academic papers in science and technology is often taken as a gauge of national scientific prowess. China has been investing heavily in scientific research and technological development in recent years to strengthen its innovative capacity. As China’s economy has soared to the second place in the world, the country’s scientific strength has als surged, if only measured by the numbers.
According to recent data by Elsevier, it is revealed that Chinese researchers published more than 1.2 million papers from 2006 to 2010, second only to the US but well ahead of UK, Germany and Japan. This figure represents a 14% increase over the period from 2005 to 2009. However, these impressive numbers mask an uncomfortable fact that most of the papers are of low quality or have little influence.
When measured by the citation per article (CPA), which measures the quality and impact of the papers, China fall below emerging countries like Indica and Brazil with a CPA of 1.47. Among papers lead-authored by Chinese researchers, most citations were by domestic peers and in a lot of cases, were self-citations.
