This paper analyses the patterns of Danish research productivity, citation impact and (inter)national collaboration across document types 2000–2012, prior to and after the introduction of the Norwegian publication point-based performance indicator in 2008. Document types analysed are: research articles; conference proceedings papers excluding meeting abstracts; and review articles. The Danish Research & Innovation Agency’s basic statistics combined with Web of Science (WoS) are used for data collection and analyses. Findings demonstrate that the research article productivity increases steeply (37 %) after the start of the performance indicator and the citation impact progresses linearly over the entire period, regardless the introduction of the performance indicator. Academic staff progression is only 24 % during the same time period. The collaboration ratio between purely Danish and internationally cooperated research articles remains stable during the period, the number of collaborative countries increases while the ratio declines significantly for proceedings papers. The citation impact of internationally cooperated research articles increases since 2009 but drops for proceedings papers; also their productivity declines slightly from 2009 according to Research Agency statistics. Since 2006 the WoS indexing of proceedings papers is fast declining; as a consequence the ratio between Danish proceedings papers and research articles declines in WoS. According to Research Agency statistics a decline likewise takes place, starting from 2009. The positive growth in research articles mainly derives from the Science and Technology fields published in prestigious Level 2 journals; the development of articles published in less prestigious Level 1 journals derives from all fields. Three of the eight Danish universities have significantly altered their research publication profiles since 2009. The publication performance model is regarded as the significant accelerator of these processes in recent years.
