In an article in VOX, Luc Bauwens,Giordano Mion, Jacques-Francois Thisse show that apart from low research budget and poor governance of academic institutions, lack of proficiency in English is also important factor for the poor performance of European academic research. http://www.voxeu.org/index.php?q=node/834. They explain this citing example of the better performance in the European countries where English proficiency is high like Sweden, Netherland and Denmark compared to countries where it is low like Germany, France and Italy. It even goes on to point out that the former English countries like Australia,Canada,New Zealand, Singapore,Israel Ireland etc. performed much higher when measured in terms of Highly Cited Research (HCR) counts per million. Of course this study is based more on the Thomson Database only. But seems the researchers are quite right in their assumptions.
As usual there is no mention about Indian or Chinese research capabilities. But a look at the site based on which the data is derived shows India has only 9 HCRs while Chinese have around 19 HCRs of which most of them are from Hong Kong (another former English Colony).
For the Education Departments in European countries this should be another wakeup call to be proactive. They are already under pressure to increase the emphasis on English because of the dilution of the other languages after the expansion of EU.
