The United States is still the world leader in scientific research, at least in biomedical research published in top journals, and has the most money on R & D. According to the American Academy of Interests website reported on June 15, some scientists today said in the Clinical Review Journal, which may not last long.
The researchers found that the role of the United States in the scientific community is slowly weakening, mainly because China has invested heavily in science for nearly two decades. In 2005, China's biomedical research team ranked fourth in the top ten in terms of new discoveries published in six top journals, the researchers said. Researchers said that in 2000, China did not even enter the top ten (ranked 14th).
In addition, the researchers said that China's investment in research and development in 2015 is 75% of the United States. In 2000, China's investment was only 12% of the United States.
However, the future of the study may be collaboration. Researchers say more scientists from the United States and around the world are making new discoveries and advances through working with international partners.
According to the report, in order to better understand the leading position in the field of science, the researchers visited the top journals from 2000 to 2015 ("American Medical Journal", "Lancet", "New England Journal of Medicine" , "Cell", "natural" and "science") and four intermediate journals. The researchers also analyzed the R & D investment in each country during this period.
Researchers have found that funding for research in the United States, Canada, Australia, the UK, and other European countries has been stagnant over the past 15 years, while China has seen a significant increase in capital.
The number of biomedical research papers published in the higher rank journals in the top ten countries in the United States, Britain, Germany, China, France / Japan, Switzerland, Canada, the Netherlands, Australia, Korea / Sweden / Italy.
At the same time, 15 countries with the largest investment in biomedical research and development include the United States, China, Japan, Germany, France, UK, Canada, Australia, Italy, Spain, the Netherlands, Sweden, Switzerland, South Korea and Singapore.
The researchers said the analysis shows that South Korea and Singapore's ranking is also rising slowly.
Researchers say the results show that the United States may one day lose its leadership in scientific and medical research.
They found in the study that although scientists born in China, scientists studying in the United States used to stay here, but now they will return to China after completing their studies.
However, the United States still has a competitive advantage. Researchers say the federal budget for the 2017 federal government has increased funding for the US National Institutes of Health, thanks to the support of both parties.
But the researchers say the current debate on the 2018 budget is worrying because someone advocates cutting money. At the same time, China's R & D investment is expected to surpass the US by 2022.
