At the Chinese Academy of Sciences, new members are elected biennially. Before 2014 only a maximum of 60 members could be inducted each time, but this restriction has since been removed by new bylaws. The candidates are nominated by current members or academic groups, although foreign members and senior members cannot nominate new candidates. Self nomination is also not allowed. Available candidates are approved by presidiums of academic divisions. Elections are held by secret ballots, and about 20% of the candidates are elected.
The membership system has been criticized as highly bureaucratic. Academicians receive government benefits equivalent to those enjoyed by vice-ministerial level officials. Additionally, academicians can receive numerous subsidies from the local governments in addition to statutory subsidies. Their opinions may carry more weight, which sometimes leads to academic monopolization.
As of September 2014, there are 738 living academicians across different divisions. 141 members constitute the Division of Mathematics and Physics, 126 in the Division of Chemistry, 136 in the Division of Life Sciences and Medicine, 122 in the Division of Earth Sciences, 86 in the Division of Information Technical Sciences, and 131 in the Division of Technological Sciences. 507 former members are deceased. 94% of the members are male, and 6% are female.
