中國以令人驚訝的速度，悄悄成為世界第二大科學(xué)知識產(chǎn)出者，僅次于排名第一的美國照.照這樣發(fā)展下去，中國將在2020年左右趕上或超過美國，屆時世界將呈現(xiàn)不同景象。歐美這些歷史上的科學(xué)統(tǒng)治者將不得不適應(yīng)新的世界秩序。

China is on course to overtake the US in scientific output possibly as soon as 2013 - far earlier than expected.

China's surge in progress could soon overwhelm the US, say experts

That is the conclusion of a major new study by the Royal Society, the UK's national science academy.
The country that invented the compass, gunpowder, paper and printing is set for a globally important comeback.

An analysis of published research - one of the key measures of scientific effort - reveals an "especially striking" rise by Chinese science.

The study, Knowledge, Networks and Nations, charts the challenge to the traditional dominance of the United States, Europe and Japan.

The figures are based on the papers published in recognised international journals listed by the Scopus service of the publishers Elsevier.

'No surprise'

In 1996, the first year of the analysis, the US published 292,513 papers - more 10 times China's 25,474.

By 2008, the US total had increased very slightly to 316,317 while China's had surged more than seven-fold to 184,080.

Previous estimates for the rate of expansion of Chinese science had suggested that China might overtake the US sometime after 2020.

But this study shows that China, after displacing the UK as the world's second leading producer of research, could go on to overtake America in as little as two years' time.

"Projections vary, but a simple linear（線的） interpretation of Elsevier's publishing data suggests that this could take place as early as 2013," it says.

Professor Sir Chris Llewellyn Smith, chair of the report, said he was "not surprised" by this increase because of China's massive boost to investment in R&D.

Chinese spending has grown by 20% per year since 1999, now reaching over $100bn, and as many as 1.5 million science and engineering students graduated from Chinese universities in 2006.

"I think this is positive, of great benefit, though some might see it as a threat and it does serve as a wake-up call for us not to become complacent（自滿的） ."

The report stresses that American research output will not decline in absolute terms and raises the possibility of countries like Japan and France rising to meet the Chinese challenge.

"But the potential for China to match American output in terms of sheer（絕對的，透明的） numbers in the near to medium term is clear."
