Cooperation patterns in science within Europe: the standpoint of small countries

This article is concerned with the cooperation patterns of science among European countries from the viewpoint of small countries. This is an issue, which empirical literature so far has overlooked, but which is still relevant for understanding the implications of integration processes in EU. We have replicated and expanded in sample, indicator and time dimensions the empirical analysis suggested by Frenken (Economic Systems Research 14(4):345-361, 2002) for assessing the homogeneity of cooperation patterns among European countries. We find that small states are less homogenously collaborating with all countries in the European research system and their intra-national research cooperation is also more fragmented. Our analysis reveals the outcomes of cooperation processes, and also highlights the factors such as research funding and research specialisation that can impact the results of the connectivity measurement. We also show that the results are sensitive to the size and measurement of the science system.
