Turkey today combines a highly centralized state with a mixed economy. Since the early 1980s, the Turkish economy has been undergoing a structural transformation, moving away from direct government regulation and control towards greater reliance on market forces. Although Turkish R&D institutions are not very well equipped in comparison with other OECD countries and member countries of the EU, they have a relatively high level of publication activity. Within 50 countries with more than 1,000 publications over a five-year period, Turkey has advanced from 42nd place between 1985 and 1989 to 36th place in the period between 1989-93, leaving Ireland, Hong Kong, Chile, Saudi Arabia and Nigeria behind. Turkish publication productivity in 1994 lifted Turkey to 34th place in a table based on national publication output in the sphere of basic sciences, engineering and health sciences. In terms of the publication rate, behind the ten world leaders of scientific research and publications. Turkey is at a turning point with regard to R&D policy.
Status about the different subjects in which extensive research is going on: Over the last decade, Turkey's GDP (gross domestic product) has grown significantly, prompting the government to increase its R&D spending. Turkey increased its research and development expenditure from 0.54 percent of GDP in 2001 to 0.86 percent in 2011, according to the Surgery journals Turkey and Turkish Statistical Institute (TUIK). In research output, Turkey ranks number 18 of the world's top 20 countries (based on number of articles among list of Surgery journals published between 2006 and 2010) and is already a definitive global competitor. Although it is on the lower end in terms of the number of articles published, it is at the top in terms of the rate of growth – at number 4, behind only China, India and Brazil.The key to increasing the international scientific influence is to increase international collaboration. Although Turkey's growth of research output is increasing rapidly, it has long way to go to be a leader in international collaboration compared to Turkey Surgery journals list and developing countries. The establishment of the surgery journals and the Scientific and Technological Research Council of Turkey (Turkish: Türkiye Bilimsel ve Teknolojik Ara?t?rma Kurumu, TÜB?TAK) is a national agency of Turkey whose stated goal is to develop "science, technology and innovation" (STI) policies, support and conduct research and development with support from list of surgery journals Turkey.
