"Nihon Keizai Shimbun" recently reported that China's research capabilities in the field of clean energy have jumped significantly. From 2011 to 2020, China published about a quarter of the global total in the number of energy research papers related to decarbonization.
According to the "Nihon Keizai Shimbun" report on the 11th, Dutch academic publishing giant Elsevier analyzed 1.6 million decarbonization-related energy research papers and about 800,000 patents published globally from 2001 to 2020, covering fields Including batteries, renewable energy, energy-saving semiconductors, electric vehicles, nuclear fusion, etc. The analysis found that among the decarbonization-related energy research papers published around the world from 2011 to 2020, Chinese papers accounted for 26.8 percent (340,000 papers), the United States accounted for 15.7 percent (200,000 papers), and Japan accounted for 4.5 percent (57,000 papers). ). China is very active in research on lithium-ion batteries, photocatalysts, wind power and other fields.
Raws li cov ntaub ntawv los ntawm Elsevier, Tuam Tshoj tau dhau lub tebchaws United States nyob rau hauv 2012 nyob rau hauv cov nqe lus ntawm tus naj npawb ntawm decarbonization- hais txog lub zog tshawb fawb cov ntaub ntawv luam tawm txhua xyoo; thiab hais txog tus naj npawb ntawm cov ntaub ntawv hauv txhua qhov kev kawm, Tuam Tshoj tsuas yog hla Tebchaws Meskas xyoo 2020. Nws tuaj yeem pom tau tias Tuam Tshoj tau pib ua ntej ntawm lub zog huv si- ntsig txog kev tshawb fawb.
Elsevier calculates the paper quality indicators based on the number of citations of the paper, and the United States still leads the way. From 2011 to 2020, China's decarbonization-related energy research paper quality index was 1.531, higher than the world average of 1.437, but lower than the US's 2.023. The quality index of Japanese papers in this field is 1.393, which is lower than the world average.
