The paper investigates international scientific competitiveness in institutions having a primary research profile in police sciences. This ever-increasing competition between institutions fits into the processes of a change of scientific approach at the level of individual researchers, institutions, and countries. Its dominating process is the “marketization” of science, as it becomes the source of earning of researchers. Another important process is the increasing role and significance of the international university rankings as an effective tool of performance evaluation of institutions. Six institutions are involved in the empirical analysis, including the Central Police University, College of Policing, Israel Police, National Research Institute of Police Science, Royal Canadian Mounted Police, Shandong Police College. Findings show that 79 percent of the total publications are published in journals, followed by conference proceedings and review articles. Social science research articles are in the 6th place with a total of 266 articles, while medicine is the leading discipline with 1,088 publications. By measuring the publication performance, the most popular topics can be identified as well. This list is dominated by the topic titled „Homicide; Serial Killer; Murderers”. Analyzing the co-author network, a very active and intensive network can be drawn between the institutions. Joining this network should be a hot priority for the Hungarian institutions as well, primarily for the Faculty of Law Enforcement of the University of Public Service.
