Objective: This paper aims to find out the factors that are likely to increase the citation impact of Turkey-addressed international papers. Method: For this purpose, we downloaded bibliographic records of some 226,000 TR-addressed papers that were published between 2006 and 2015, there from selected a sample (2%) using stratified probabilistic sampling technique, and obtained relevant data from various sources such as the number of citations and coauthors, journal impact factors (JIF) and journal quartiles pertaining to each paper in the sample. We then identified 19 independent variables on article, journal, cooperation, support and access levels and analyzed the data using the hurdle model. Findings: The strongest factors increasing the number of citations of TR-addressed papers are five-year JIFs and journal quartiles (Q1) in which TR-addressed papers appeared and the number of references in papers' reference lists. These factors also reduce the number of papers with zero citations. Papers published in cooperation with other countries collect higher numbers of citations. Factors such as the subjects of papers, whether papers received monetary support or not, and methods by which papers can be accessed (open or closed access) have no impact on the number of citations received. Implications: Findings indicate that academic promotion and support policies encouraging publishing in high impact journals while forestalling publishing in low impact journals should be developed in order to increase the scientific impact of TR-addressed papers. Originality: This is the first study using hurdle model to investigate the direct impact of several article, journal, collaboration, monetary support and access level explanatory variables on the number of citations that TR-addressed papers receive.
