Background and aim: Due to the limited financial and human resources, determining the research priorities are the most important issues facing science and technology policymakers. This study determined the Iranian research priorities from economic approach.

Material and Methods: This study is applied research with scientometrics and econometrics methods. SCImago and Gross Domestic Product Per capita (GDPP) data were extracted from World Bank database and data were analyzed by EViews 7 software.

 Findings: Engineering and Human Science groups (0.01 level) have affected GDPP. Human science (0.01 level), Medicine and Veterinary (0.05 level) groups have been affected by GDPP.

 Conclusion: Biomedical Engineering, Building and Construction, Control and Systems Engineering, Industrial and Manufacturing Engineering, Mechanical Engineering, Material Science and the Mechanics of Material fields have affected economic growth. In other words, these fields can be placed in Iranian research priorities.
