asia: the growing hub of scientific research

asianscientist | The scientific global village has a new member: Asia. The shifting face of science reflects the strides made by Asian nations in recognizing R&D as a valuable industry.

• Asia-8′s R&D expenditure is second only to the US, surpassing the EU-27
• One-third of all scientific researchers worldwide are Asian
• One-quarter of the world’s publications are from Asia
• China’s scientific publishing output may overtake the US in 2013

The Asian research landscape is dynamic and burgeoning, with its researchers making significant contributions in academic publications, research & development, and high-technology manufacturing and exports.

The emerging Asia-8 economies (China, India, Japan, Malaysia, Singapore, South Korea, Taiwan and Thailand) are currently leading this change in status quo, driving a shift from the traditional hubs of research in the US and countries in the EU-27.

Asian R&D Spending Has Risen

An important measure of an industry’s growth, Asian R&D expenditure has grown significantly with China’s spending now US$100 billion of the worldwide total of US$1.1 trillion in 2007.

In figures from the 2010 National Science Foundation Key Science and Engineering Indicators, spending by Asia-8 economies have now reached second place behind the US, surpassing those of the EU-27. Overall, R&D growth in US and Europe has plateaued, averaging 5-6 percent annually over the period 1996–2007, whereas R&D growth rates of Asian economies during the same period often exceeded 10 percent, with Chinese spending growing at 20 percent since 1999.

Reflecting an increase in private spending by domestic and foreign firms as well as public R&D spending, Asia-8 member Singapore has nearly doubled its spending between 1996 and 2007 from 1.37 to 2.61 percent of its GDP. This unprecedented growth is part of the island nation’s policy designed to raise its competitiveness through the development of a knowledge-intensive economy.

One Out Of Three Researchers Are Asian

Other signs of a shift in research can be observed by the distribution of researcher nationalities. Asia now contributes nearly one-third of the 5.8 million researchers worldwide.

The combined number of researchers of South Korea, Taiwan, China, and Singapore rose from 16 percent in 2003, to 31 percent in 2007, driven mostly by China’s rapid growth in R&D. In contrast, the number of US and EU researchers declined from 51 to 49 percent; Japan’s share dropped from 17 to 12 percent.

There has also been a surge in a new generation of researchers from Asia, with 1.5 million students in China alone currently enrolled in postgraduate programs. This number is an increase in 57 percent compared to the previous year, according to the Chinese National Bureau of Statistics (NBS). In total, China has 31 million students in higher education institutions in 2010, an increase of 35 percent compared to 2005, and almost double compared to 2002.

Publication Output From Asia Is Increasing

Another metric – publishing output – indicates that the world’s scientific hub is slowly shifting east. Between 1995 to 2007, the growth rate in science and engineering article output from mature economies of the US (0.7 percent) and EU (1.9 percent) has plateaued, in contrast to the rapidly developing science base of Asia-8 countries (9.0 percent) and China (16.5 percent).

Although the UK and US together still account for 38 percent of publications in 2004-2008, this figure is down from 45 percent in the previous five years. This is contrasted by Asia-8, China and Japan, which now account for 22 percent of the world’s total academic publication output. Singapore’s output, though small in comparison, has tripled between 1996 and 2008, from 2620 to 8506 papers.

Together, China and Spain have now edged Australia and Switzerland out of the top ten publishers for the last five years.
