The world network of scientific collaborations between cities: domestic or international dynamics

  1. 1. The world network of scientific collaborations between cities: domestic or international dynamics? Marion Maisonobe*, Denis Eckert, Michel Grossetti, Laurent Jégou, Béatrice Milard *marion.maisonobe@univ-tlse2.fr, UMR LISST-CIEU, CNRS, Toulouse (France) Fédération INCREASE, CRIEF, Poitiers (France) 21st International Conference on Science and Technology Indicators Valencia, Spain – September 14-16, 2016
  2. 2.  Dataset : the SCI Expanded  More than a million publications per year between 1999 and 2010  Two step method 1. Geocode addresses of authors for each publication 2. Assign data at the urban area level  Analyze the spatial distribution of scientific activity and exchanges between cities through co-authorship data Dataset and method
  3. 3. Web visualization tool shared among all project participants to control the results of automatic geocoding processes and delineate urban areas’ perimeters (developed in 2010 with OpenLayers)
  4. 4. Counting method : the case of an article co-signed by 16 authors in Paris and Toulouse An only link : Paris-Toulouse Value = 1 Publication weight : Paris = 0,5 Toulouse = 0,5 Whole Normalised Counting (Gauffriau et al, 2008)

  14. 14. For countries where there is a growing dispersion of scientific activities, the growth of interurban collaborations is more pronounced within national boundaries than between them. Growing autonomy and polycentrism for developing countries !
