Ranking Countries by Scientific Publication Citations: USA, UK, Germany…
Posted on January 24, 2015 Comments (1)
The SCImago Journal and Country Rank provides journal and country scientific indicators developed from the information contained in the Scopus database. I posted about this previously (in 2014, 2011 and 2008).
The data in the post is based on their data from 1996 through 2013. The web site also lets you look at these ranking by very specific categories. For example biotechnology #1 USA, #2 Germany, #3 UK, #4 Japan, #12 China or human computer interaction #1 USA, #2 Germany, #3 UK #4 Japan, #13 China).
I like looking at data and country comparisons but in doing so it is wise to remember this is the results of a calculation that is interesting but hardly definative. We don’t have the ability to measure the true scientific research output by country.
The table shows the top 6 countries by h-index and then some others I chose to list.
|% of World
|% of World GDP||total cites|
|Additional countries of interest (with 2013 country rank)|
|19) South Korea||375||258||161||.7||1.7||5,770,844|
This data makes a good case for the USA, UK, Germany… producing a very high level of very influential science publications. Whether Italy (#7) is obviously more influential than Brazil (#22) or India (#23) I think is fairly questionable.
Read more about the h-index (Hirsh index). Country population and GDP data taken World Development Indicators 2013, by the World Bank.
Without doing any analysis it seems to me the data shows that scientific influence is heavily correlated with GDP (and also GDP per capita). Also while GDP changes (for a country as a percent of world GDP) generally are fairly slow (China’s may not be but nearly everyone else is) I would guess scientific influences is even slower to change – but it will change in a fashion correlated with relative GDP.
My belief is there is a system reinforcing effect, greater GDP allows more scientific research (and investing in universities, etc.) which increase economic growth down the road, which provides more income to invest in scientific research and so on.
Some countries, the USA for example, are more effective at turning scientific research into GDP gains. Where countries are more effective at doing so it reinforces investing in science. It also encourages leading scientists interested in business applications to be tempted to move to the USA which then helps the USA scientific influence and so on.
