[2013 research ranking of Spanish public universities].

Background: The evaluation of research production and productivity is becoming increasingly necessary for universities. Having reliable and clear data is extremely useful in order to uncover strengths and weaknesses. The objective of this article is to update the research ranking of Spanish public universities with the 2013 data.

Method: Assessment was carried out based on articles in journals indexed in the JCR, research periods, R+D projects, doctoral theses, FPU grants, doctoral studies awarded with a citation of excellence, and patents, providing a rating, both for each individual indicator and globally, in production and productivity. The same methodology as previous editions was followed.

Results: In the global ranking, the universities with a higher production are Barcelona, Complutense of Madrid, and Granada. In productivity, the first positions are held by the universities Pompeu Fabra, Pablo de Olavide, and the Autonomous University of Barcelona.

Conclusions: Differences can be found between the universities in production and productivity, while there are also certain similarities with regard to the position of Spanish universities in international rankings.
