The relative influences of government funding
  and international collaboration on citation impact 
Loet Leydesdorff, Lutz Bornmann, and Caroline S. Wagner

In a recent publication in Nature, Wagner & Jonkers (2017) report that 
public R&D funding is only weakly correlated with the citation impact of 
a nation's papers as measured by the field-weighted citation index 
(FWCI; defined by Scopus). On the basis of the supplementary data, we 
upscaled the design using Web-of-Science data for the decade 2003-2013 
and OECD funding data for the corresponding decade assuming a two-year 
delay (2001-2011). Using negative binomial regression analysis, we find 
very small coefficients, but the effects of international collaboration 
are positive and statistically significant, whereas the effects of 
government funding are negative, an order of magnitude smaller, and 
statistically non-significant (in two of three analyses). In other 
words, international collaboration improves the impact of average 
research papers, whereas more government funding tends to have a small 
adverse effect when comparing OECD countries.
