Purpose: This research aimed to investigate the status of research production of Iran in the field of science sicne the Islamic Revolution and comparing it with the world scientific production as well as to identify the contribution of Iran in production of world research publications in the field of science and its sub-disciplines (the 22 branches of science) during this period.
Methodology: This research is an applied bibliometric study. The research population included all of the indexed scientific outputs of Iran and the world in the Science Citation Index (SCI) during 1980-2016. The total number of scientific productions of Iran in the field of science during the studied period was 267626 items and the total number of scientific productions of the world at the same time was 40297747 items, all of which were census-based.
Findings: The results of the Yi index, which examines the status of different branches of science in a country, showed that the fields of chemistry (with 16.95% of the total scientific production of Iran), clinical medicine (with 14.84% of the total scientific production of Iran), engineering (with 12.80%), physics (with 8.7%) and material sciences (with 7.20%) have had better performance among twenty-two branches of science and these five categories have been the largest contributors in science production of Iran. Xi index which examines the global contribution of a country in various scientific fields showed that mathematics (0.66%), engineering (0.63%), chemistry (0.57%) and agriculture (0.53%) had higher rate than Xi of 0.05%, respectively. Other fields had lower Xi than 0.5%. Sx or scientific poverty index which examines the relative performance of countries according to the percentage of the country's population from the entire world population, showed that, Iran's situation in each of the twenty-two subject areas was below the scientific poverty line (below one percent) during 1980-2009, but since 2009, it has risen to over 1 percent, and has actually risen above the poverty line, and even exceeded 2 percent in some areas. The examination of the index in all areas in the country from 1980 to 2016 also showed that the index reached 1.19 percent in 2009 to about 2 percent (1.99 percent) in 2016.
Conclusion: Improving the status of science production indicators of Iran in the fourth decade after the Islamic Revolution has improved the status of various indicators of scientometrics and this improvement in performance has led to the passage of the poverty line in Iran. Therefore, the per capita production of Iranian science from world science production reached 1.11 percent in 2009 to 1.86 percent in 2016. By the end of 2016, about two percent of the total production of world science (indexed in SCI) was produced by Iranian researchers.
