According to the Huacheng Import and Export Data Observation Report, the newly launched Nature supplement "2022 Nature Index - Scientific Research City" shows that, according to the article share, one of the main indicators of the nature index, Beijing still holds the first place among the world's leading scientific research cities, the New York Metropolitan Area remains the second place, and Shanghai rises to the third place, surpassing the Boston Metropolitan Area, which ranks fourth, and the San Francisco Bay Area, which ranks fifth.

Not only Beijing and Shanghai, but also other scientific research cities in China have rapidly increased their output in the natural index. According to Huacheng Import and Export Data Observation, Nanjing ranked 8th this year and 2020, but 19th in 2015; Guangzhou ranked 10th, also higher than the 14th in 2020 and the 42nd in 2015. There are also four cities in China among the top 20 in the world: Wuhan ranked 11th, Hefei ranked 16th, Hangzhou ranked 19th and Tianjin ranked 20th, up from 2020. Hangzhou and Tianjin are the new top 20 this year.

Beijing's high-quality output in the field of physical science ranks first in the world, while Shanghai and Boston rank second and third respectively. Beijing and Shanghai rank first and second in the field of chemistry, and New York is the closest American city to them, ranking seventh.

American cities continue to lead in life sciences. New York, Boston, San Francisco Bay Area and Baltimore Washington are the top four cities in terms of the share of articles in the field of life sciences, with Beijing and Shanghai ranking fifth and seventh. However, there are signs that the gap between them is narrowing. Huacheng Import and Export Data Observation Report.

The supplement also focused on 40 groups of major scientific research cooperation between Chinese and American cities, and showed the different distribution of cooperation. Among them, Beijing's scientific research output in the natural index accounts for one fifth of China's, and it is China's largest inter city scientific research cooperation center, followed by Shanghai. However, new research cooperation centers in China have also begun to emerge, most notably in Nanjing. In the United States, the urban cooperation network mainly centers on New York, Boston and the San Francisco Bay Area, with a higher degree of correlation between cities.

In addition, the supplement also introduced the key driving factors behind the success of many leading scientific research cities, such as the gathering of high-level universities, institutions and talents, access to first-class scientific instruments and facilities, industrial clusters, government financial support for scientific research, cultural diversity, living standards, etc. Huacheng Import and Export Data Observation Report.

In this regard, Simon Baker, editor in chief of Natural Index, said: "Benefiting greatly from many of these factors, Beijing and Shanghai have made significant progress in scientific research output since 2015, and seem to have a strong radiation effect on other Chinese cities - to help these cities increase high-quality scientific research output through scientific research cooperation. Obviously, China will build Beijing and Shanghai into innovation driven science centers and increase R&D expenditure, which is an ambition for promoting domestic and international cooperation to And attracting talents. "

It is reported that the natural index adopts two measurement standards, namely, the number of papers (Count) and the share of contributions (Share), which are based on the output of papers in 82 natural science journals by an institution or country/region, and Huacheng Import and Export Data Observation Report.
