Apart from a few bibliometric studies of limited scope, the Pakistani scientific system is a scantly researched area requiring large-scale empirical evidence-based studies. This study aims to explore various features of collaboration in research and its impact on the performance of computer scientists in Pakistan. Over 15,494 SCOPUS-indexed publications in the area of computer science for the period 1997 to 2017, having at least one Pakistani author, were analyzed. The findings of the study disclosed the important role of collaboration in the citation count of the publications. International collaborative works and the more countries in collaboration significantly impacted the number of citations. The study's findings revealed that collaborative publications are more frequently cited and considered of high quality. This study is the first large-scale quantitative analysis of research collaboration, represented by co-authorship in computer science research in Pakistan.
