This document presents a typology of scientific agglomeration forms based on an analysis of publication data from 2000-2010. It identifies 5 types: 1) monocephalic agglomerations with a single center; 2) agglomerations with a single decentralized center, including those with a more dynamic suburb; 3) agglomerations with multiple decentralizations; 4) two close agglomerations within or across borders; 5) emergence of new centers. Examples of each type are shown on maps with publication data from two time periods to illustrate spatial configurations and evolutions.
4. Data processing
• Biases acknowledged :
• WoS journals (english language mainly, slow perimeter évolution)
• Authors’ postal addresses / postal districts variation
• Automatic geocoding sometimes wrong (Leuven / Louvain …)
• Results :
• 20M publications, 40M authors
• geocoded worldwide and fractionated on 35.000 cities
• moving averages for 1999-2001 and 2009-2011, evolutions
• Several publications (Urban studies, journals, doctoral thesis …)
A new tool to represent the centers of scientific publication at the
city scale and its evolution since 1999.
5. A new dynamic map online tool
(Hopefully soon to be available freely online)
6. Focus of today’s presentation :
agglomerations
• Illustrating the diversity of the spatial configuration of the scientific
production.
• A typology of spatial forms taking into account the temporal
evolution.
7. Type 1 : the monocephalic or
centralised agglos.
A single centre of publications only, stable in time (no new centres of
production in the agglomeration during the period).
11. Type 2 : agglomerations with a
single decentralised scientific
centre
Subtype 2a : With one suburb more
dynamic than the centre
Very often, the second centre of scientific production is a university
campus, decentralised or delocalised from an old city-centre campus.
