Book excerpt: China's Scientific Elite is a study of those scientists holding China's highest academic honour - membership of the Chinese Academy of Sciences. Having carried out extensive systematic data collection of CAS members Cao examines the social stratification system of the Chinese science community and the way in which politics and political interference has effected the stratification. The book then goes on to compare the Chinese system to the stratification of the US scientific elite. The conclusions are fascinating, not least because one national elite resides in a democratic liberal social system, and the other in an authoritarian social system.
