Strength and weakness of national science systems: A bibliometric analysis through cooperation patterns

In this study we have focused on long term developments of various types of scientific publishing, and the field-normalized impact generated by these various types. The types of scientific output distinguished are output resulting from international cooperation, national cooperation, and single address publications, in which no apparent cooperation is found. A fourth type is distinguished by focusing on first authorship, within the international cooperation output. Changes in especially the share of a country's output from first-authored international cooperation and the share of single address publications can be regarded as indicators of strength and/or weakness of a science system.
