The Chinese Academy of Sciences has historical origins in the [[Academia Sinica]] during the [[Republic of China (1912–49)|Republican era]] and was formerly also known by that name until the 1980s. The academy functions as the national scientific [[think tank]] and academic governing body, providing advisory and appraisal services on issues stemming from the national economy, [[Social change|social development]], and science and technology progress. It is headquartered in [[Beijing]], with affiliate institutes throughout China. It has also created hundreds of commercial enterprises, [[Lenovo]] being one of the most famous. 

CAS also runs the [[University of Science and Technology of China]] and the [[University of the Chinese Academy of Sciences]],<ref name=":8">{{Cite web|title=中国科学院教育简介 — 中国科学院|url=https://www.cas.cn/rcjy/zkyjyjj/201704/t20170411_4596697.shtml|url-status=live|access-date=2022-01-24|website=Chinese Academy of Sciences|archive-url=https://web.archive.org/web/20170522052624/http://www.cas.cn:80/rcjy/zkyjyjj/201704/t20170411_4596697.shtml |archive-date=22 May 2017 }}</ref> both of which were among the world's top three academic institutions in the [[Nature Index]] rankings as of 2024.<ref name=":2">{{Cite web |title=2024 Research Leaders: Leading academic institutions {{!}} Nature Index |url=https://www.nature.com/nature-index/research-leaders/2024/institution/academic/all/global |access-date=2025-01-18 |website=nature.com |archive-date=7 October 2024 |archive-url=https://web.archive.org/web/20241007120240/https://www.nature.com/nature-index/research-leaders/2024/institution/academic/all/global |url-status=live }}</ref><ref>{{Cite web |title=2024 Research Leaders: Leading institutions {{!}} Nature Index |url=https://www.nature.com/nature-index/research-leaders/2024/institution/all/all/global |access-date=2025-01-18 |website=nature.com |archive-date=9 October 2024 |archive-url=https://web.archive.org/web/20241009173648/https://www.nature.com/nature-index/research-leaders/2024/institution/all/all/global |url-status=live }}</ref> CAS has also founded and spun off multiple companies, such as [[Sugon]] and GoLaxy.<ref>{{Cite news |last=Barnes |first=Julian E. |date=2025-08-06 |title=China Turns to A.I. in Information Warfare |url=https://www.nytimes.com/2025/08/06/us/politics/china-artificial-intelligence-information-warfare.html |access-date=2025-08-20 |work=[[The New York Times]] |language=en}}</ref>

Membership of the Chinese Academy of Sciences, also known by the title Academician of the Chinese Academy of Sciences ({{zh|中国科学院院士|labels=no}}), is a lifelong honor given to Chinese scientists who have made significant achievements in various fields. According to the ''Bylaws for Members of the Chinese Academy of Sciences'' adopted in 1992 and recently amended in the year 2014, it is the highest academic title in China. A formal CAS member must hold [[Nationality law of the People's Republic of China|Chinese citizenship]], although foreign citizens may be elected as CAS foreign academicians. Members older than 80 are designated as "senior members" and may no longer hold leading positions in the organization.<ref name="bylaws">{{cite web |url=http://www.casad.cas.cn/document.action?do |title=中国科学院院士章程 [Bylaws for Members of the Chinese Academy of Sciences] |publisher=Chinese Academy of Sciences |access-date=16 September 2014 }}{{Dead link|date=September 2024 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> Academicians of the Chinese Academy of Sciences carry an obligation to advance science and technology, to advocate and uphold scientific spirit, to develop a scientific and technological workforce, to attend member meetings and receive consultation and evaluation tasks, and to promote international exchanges and cooperation. Academicians can give suggestions and influence Chinese state policy related to science and technology.<ref>{{cite web|url=http://english.casad.cas.cn/Me/OR/200905/t20090515_3152.html|title=Obligations and Rights of a CAS Member|publisher=Academic Divisions of the Chinese Academy of Sciences|access-date=16 September 2014|archive-date=6 October 2014|archive-url=https://web.archive.org/web/20141006101220/http://english.casad.cas.cn/Me/OR/200905/t20090515_3152.html|url-status=live}}</ref>

==History==
In 1956, China formally began its computing program when it launched the Twelve-Year Science Plan and formed the Beijing Institute of Computing Technology under the CAS.<ref name=":Mullaney2">{{Cite book |last=Mullaney |first=Thomas S. |title=The Chinese Computer: a Global History of the Information Age |date=2024 |publisher=[[The MIT Press]] |isbn=9780262047517 |location=Cambridge, MA}}</ref>{{Rp|page=100}}

In 1964, CAS debuted China's first self-developed large [[Computer|digital computer]], the 119.<ref name=":Mullaney2" />{{Rp|page=101}} The 119 was a core technology in facilitating China's first successful nuclear weapon test ([[Project 596]]), also in 1964.<ref name=":Mullaney2" />{{Rp|page=101}}

Beginning in 1972, CAS began promoting the idea of balancing applied research with more theoretical research and in having scientific exchanges with other developing countries.<ref name=":Minami">{{Cite book |last=Minami |first=Kazushi |title=People's Diplomacy: How Americans and Chinese Transformed US-China Relations during the Cold War |date=2024 |publisher=[[Cornell University Press]] |isbn=9781501774157 |location=Ithaca, NY}}</ref>{{Rp|page=74}} 

As vice premier, [[Deng Xiaoping]] in 1975 also sought to re-orient CAS towards more theoretical research, which had not been a focus during the [[Cultural Revolution]].<ref name=":Minami" />{{Rp|page=74}} Deng emphasized that "the Academy of Sciences is an Academy of Sciences, not an Academy of Cabbage."<ref name=":Minami" />{{Rp|page=74}} Deng assigned CAS vice president [[Hu Yaobang]] to draft a plan for overhauling CAS.<ref name=":Minami" />{{Rp|page=74}} Deng and his aide [[Hu Qiaomu]] revised the draft and in September 1974 issued "The Outline Report on the Work of the Academy of Sciences".<ref name=":Minami" />{{Rp|page=74}} The Outline described scientific research in China as lagging behind the needs of socialist construction and the state of the advanced countries, and stated that to catch up, China should emphasize [[Basic research|basic science]] in order to develop a sound theoretical foundation.<ref name=":Minami" />{{Rp|page=74}}

This approach to scientific reform fell out of political favor in 1976 when Deng was purged, although it continued to be supported by many members within CAS.<ref name=":Minami" />{{Rp|page=75}} A month before Deng's political return in 1977 however, the Outline Report was revived and adopted as CAS's official policy.<ref name=":Minami" />{{Rp|page=81}}

Shortly after his return, Deng hosted a series of meetings on science and education in which he stated that science should become the forerunner of China's modernization.<ref name=":Minami" />{{Rp|page=82}} Following these remarks, CAS prepared its goals for natural science disciplines to be achieved by 1985, stating that as a developing socialist country, China should strengthen basic scientific research through foreign exchanges.<ref name=":Minami" />{{Rp|page=82}}

To further promote this agenda, Deng began a campaign to promote the National Science Conference.<ref name=":Minami" />{{Rp|page=82}} A team led by CAS vice president [[Fang Yi]] instructed schools, factories, and communes to organize youth-focused events celebrating science and technology.<ref name=":Minami" />{{Rp|page=82}}

In 1977, the Department of Philosophy and Social Sciences was split off of CAS and reorganized into the [[Chinese Academy of Social Sciences]] and led by Hu Qiaomu.<ref name=":Minami" />{{Rp|pages=86-87}}

In 1980, the CAS publication ''Journal of Dialectics of Nature'' convened its first annual National Symposium on Artificial Intelligence, which included national and international scholars like [[Herbert A. Simon]].<ref name=":122">{{Cite book |last=Frost |first=Shuang L. |title=Machine Decision is Not Final: China and the History and Future of Artificial Intelligence |publisher=Urbanomic, [[MIT Press]] |year=2025 |isbn=9781913029999 |editor-last=Bratton |editor-first=Benjamin |chapter=Translating Chinese AI: From 'Humanmade Intelligence' to 'Black Tech' |editor-last2=Greenspan |editor-first2=Anna |editor-last3=Ireland |editor-first3=Amy |editor-last4=Konior |editor-first4=Bogna}}</ref>{{Reference page|page=42}} The second annual symposium announced The Chinese Association for Artificial Intelligence (CAAI).<ref name=":122" />{{Reference page|page=42}} CAAI has continued to be the largest [[Artificial intelligence industry in China|AI]] association in China as of 2025.<ref name=":122" />{{Reference page|page=42}}

The [[Graduate School of the Chinese Academy of Sciences]] was established in 2001 as a successor to the Graduate School of the University of Science and Technology of China (Beijing).The Ministry of Education (MOE) approved the Graduate School of the Chinese Academy of Sciences (CAS) application to change its name to the University of the Chinese Academy of Sciences (UCAS) on July 23, 2012. Additionally, the MOE recommended that CAS discontinue the operation of the CAS Graduate School. In 2023, the [[Pasteur Institute]] suspended ties with CAS.<ref>{{Cite journal |last=Mallapaty |first=Smriti |date=2023-03-08 |title=Prestigious Pasteur Institute severs ties with China infectious disease lab |journal=[[Nature (journal)|Nature]] |language=en |doi=10.1038/d41586-023-00694-x |pmid=36890326 |doi-access=free}}</ref>
