Abstract:For historical reasons, the nature of legal status on Chinese Academy of Sciences (CAS) began to vague and uncertainly early from the "Organization regulation of Chinese Academy of Sciences (draft)". The present legal status of CAS is not yet confirmed by the law and regulations, which caused more instability and unreliability. Thus, it is difficult to meet the requirement to form modern governance structure of CAS. Therefore, it is suggested to reconstruct the legal status system of CAS as soon as possible, through a specific legislative proposal, a special legal status system for national research organization, a clear administrative authority for internal governance and management.
