Actually, this comparison is not very reasonable. China Academy of Sciences has six departments (Mathematics and Physics Department, Chemistry Department, Life Science and Medicine Department, Geology Department, Information Technology Science Department and Technology Department). 12 branches (established in Shenyang, Changchun, Shanghai, Nanjing, Wuhan, Guangzhou, Chengdu, Kunming, Xi 'an, Lanzhou, Xinjiang and Chongqing), 104 directly affiliated research institutions, 4 national laboratories, 85 state key laboratories and 153 key laboratories of Chinese Academy of Sciences. Kloc-0/2 field observation stations, 2 universities, 4 document information centers, 3 technical support institutions and 2 press and publication units, with more than 50,000 researchers in the hospital, distributed in more than 20 provinces (cities) in China. As far as scale is concerned, no research unit in China can compare with it. Peking University also has a strong scientific research capability, and there are several national key laboratories. The level of many fields or directions is not lower than that of relevant research units of Chinese Academy of Sciences, and some disciplines or directions are even worse. Moreover, the mutual mobility of related researchers is also strong. For example, Wang Enge, the current president of Peking University, and Xie Xincheng, the dean of the Institute of Physics, all came to Peking University from the Institute of Physics of the Chinese Academy of Sciences in recent years.
Comparing the scientific research level of these two forces, making an inappropriate metaphor is like asking an elite division of the army and a super-large joint naval fleet, which is stronger or weaker. It has no practical significance, and it is definitely greater than the total amount, but it depends on the specific direction of specific fields.
