R&D in China and India

“A great deal of the debate over globalization of knowledge economies has focused on China and India. One reason has been their rapid, sustained economic growth. The Chinese economy has averaged a growth rate of 9-10 percent for nearly two decades, and now ranks among the world’s largest economies. India, too, has grown steadily. After years of plodding along at an average annual increase in its gross domestic product (GDP) of 3.5 percent, India has expanded by 6 percent per annum since 1980, and more than 7 percent since 1994 (Wilson and Purushothaman, 2003). Both countries are expected to maintain their dynamism, at least for the near future.”

A June 16 paper in Proceedings of the National Academy of Sciences, titled ‘China’s Rise as a Major Contributor to Science and Technology’, analyses the academic and research environment in China over the last decade or so, and discusses the factors involved in the country’s increasing fecundity in recent years. It concludes that four factors have played an important role in this process:

  1. Large human capital base
  2. A labor market favoring academic meritocracy
  3. A large diaspora of Chinese-origin scientists
  4. A centralized government willing to invest in science

A simple metric they cite to make their point is the publication trends by country. Between 2000 and 2010, for example, the number of science and engineering papers published by China has increased by 470%. The next highest climb was for India, by 234%.

“The cheaters don’t have to worry they will someday be caught and punished.”

This is a quantitative result. A common criticism of the rising volume of Chinese scientific literature in the last three decades is the quality of research coming out of it. Dramatic increases in research output are often accompanied by a publish-or-perish mindset that fosters a desperation among scientists to get published, leading to padded CVs, falsified data and plagiarism. Moreover, it’s plausible that since R&D funding in China is still controlled by a highly centralized government, flow of money is restricted and access to it is highly competitive. And when it is government officials that are evaluating science, quantitative results are favored over qualitative ones, reliance on misleading performance metrics increases, and funds are often awarded for areas of research that favor political agendas.

The PNAS paper cites the work of Shi-min Fang, a science writer who won the inaugural John Maddox prize in 2012 for exposing scientific fraud in Chinese research circles, for this. In an interview to NewScientist in November of that year, he explains the source of widespread misconduct:

It is the result of interactions between totalitarianism, the lack of freedom of speech, press and academic research, extreme capitalism that tries to commercialise everything including science and education, traditional culture, the lack of scientific spirit, the culture of saving face and so on. It’s also because there is not a credible official channel to report, investigate and punish academic misconduct. The cheaters don’t have to worry they will someday be caught and punished.

At this point, it’s tempting to draw parallels with India. While China has seen increased funding for R&D…

The issue of funding is slightly different in India, in fact. While Chinese science is obstinately centralized and publicly funded, India is centralized in some parts and decentralized in others, public funding is not high enough because presumably we lack the meritocratic academic environment, and private funding is not as high as it needs to be.

Even though the PNAS paper’s authors say their breakdown of what has driven scientific output from China could inspire changes in other countries, India is faced with different issues as the charts above have shown. Indeed, the very first chart shows how, despite the number of published papers having double in the last decade, we have only jumped from one small number to another small number.

“Scientific research in India has become the handmaiden of defense technology.”

There is also a definite lack of visibility: when little scientific output of any kind is accessible to 1) the common man, and 2) the world outside. Apart from minimal media coverage, there is a paucity of scientific journals, or they exist but are not well known, accessible or both. This Jamia Milia collection lists a paltry 226 journals – including those in regional languages – but it’s likelier that there are hundreds more, both credible and dubious. A journal serves as an aggregation of reliable scientific knowledge not just for scientists but also for journalists and other reliant decision-makers. It is one place to find the latest developments.

In this context, Current Science appears to be the most favored in the country, not to mention the loneliest. Then again, a couple fingers can be pointed at years of reliance on quantitative performance metrics, which drives many Indian researchers to publish in journals with very high impact factors such as Nature or Science, which are often based outside the country.

In the absence of lists of Indian and Chinese journals, let’s turn to a table used in the PNAS paper showing average number of citations per article compared with the USA, in percent. It shows both India and China close to 40% in 2010-2011.

The poor showing may not be a direct consequence of low quality. For example, a paper may have detailed research conducted to resolve a niche issue in Indian defense technology. In such a case, the quality of the article may be high but the citability of the research itself will be low. Don’t be surprised if this is common in India given our devotion to the space and nuclear sciences. And perhaps this is what a friend of mine referred to when he said “Scientific research in India has become the handmaiden of defense technology”.

To sum up, although India and China both lag the USA and the EU for productivity and value of research (albeit through quantitative metrics), China is facing problems associated with the maturity of a voluminous scientific workforce, whereas India is quite far from that maturity. The PNAS paper is available here.
