China has become one of the world's most prolific publishers of scientific papers, producing 3.7 million papers in 2021, 23% of global output, and just behind the 4.4 million total from the US.
The quality of Chinese research has been called into question due to systemic inefficiencies and fraudulent research, including the use of "paper mills" to create fake research papers.
Pressure to publish and meet performance targets in academia has led to a focus on quantity over quality and increased fraudulent research.
Weak enforcement of penalties against paper mills has created an institutionalized incentive to cheat in order to meet citation and publication output targets.
