The Chinese Academy of Sciences, founded in 1949 – the same year as the People's Republic of China – has attempted to use science to speed up technological, economic, and defense-related development, as well as the entire process of modernization. At' the same time, political structures on the development of science have hampered scientific output and kept it to a level that was far below what might have been expected from the creative potential of China's scientists.
Early in this century, when modern science was brought to China by foreign missionaries and by scientists and students returning from abroad, only a few people in the country were engaged in scientific research. In 1928 and 1929, two state-run comprehensive research establishments were founded: the Academia Sinica, consisting mainly of scientists who had studied in the United States, and the Peking Academy, consisting mainly of European-trained scientists. Two decades later, a month after the proclamation of the People's Republic of China, a single national scientific research body was founded: the Chinese Academy of Sciences (CAS). This article will review the contribution and status of the CAS, its successes and its failures in the ensuing forty years.
