The Commission Communication entitled "A Strategy for ICT R&D and Innovation in Europe: Raising the Game" proposes reinforcing Europe's industrial and technology leadership in ICT. Building on Europe's assets, the Communication anticipates a landscape where, by 2020, "(?) Europe has nurtured an additional five ICT poles of world-class excellence (?)". This study attempts to identify ICT R&D&I-related agglomeration economies in Europe that would meet world-level excellence, and to identify weak signals that would indicate the dynamics of a changing ICT-related economic geography in Europe. Both of those identification processes are based on quantitative data, built on a set of relevant criteria leading to measurable indicators. The study is developed around several tasks, the results of which are presented in a series of EIPE reports. This second EIPE report develops an empirical assessment strategy for the identification of ICT agglomerations in Europe. It defines measures and data sources used in the study.
