CHINA’S CLOSE CONNECTIONS

PATTERNS OF DOMESTIC COLLABORATION IN MAINLAND CHINA
CAPTURED BY THE NATURE INDEX

This map shows two aspects of Chinese science. Line thickness and colour reflect the number of partnerships that formed between pairs of institutions in Chinese cities in 2016. A partnership occurs when researchers from both institutions publish joint papers in a journal included in the index.

The map also shows the high-quality research produced in mainland Chinese cities in 2016, as measured by the index. Bubbles represent the contribution of a city’s institutions to journals included in the index, a measure known as weighted fractional count (WFC). Read more about index metrics.
