Currently，there are still obstacles for patients’ right of self-determination in medical decision-making. By sorting out its historical origins，this paper found that the reasons for the current situation mainly include the influence of familial culture and medical paternalism，as well as the constraints of the behavioral capacity system and the guardianship systems. In this context，this paper criticized the view that “the key to enjoying decision-making power is rationality”，and called for a return to the concept of patient autonomy，so as to achieve a balance between agency decision-making power of others and the special intervention rights of doctors. The legal system for resolving conflicts can be constructed by replacing behavioral capacity with medical decision-making ability，requiring the evaluation of medical decision-making ability based on actual conditions，establishing a pre-medical instruction system，and clarifying the boundaries of medical special intervention rights.

OBJECTIVE：To provide reference for perfecting regional cooperation supervision mechanism under the marketing authorization holder （MAH） system in China. METHODS ：Based on the analysis of legal responsibilities of the MAH and entrusted manufacturing enterprise ，the problems were studied and suggestions for improving the regional cooperative supervision mechanism were put forward. RESULTS & CONCLUSIONS ：Sub-contract production is the main target of cross-regional collaborative supervision of drug regulatory agencies. The MAH is responsible for the entire life cycle of the drug ，and the entrusted manufacturing enterprise assumes supplementary responsibility. At present ， the problems of regional cooperation supervision are lacking of targeted legal enforcement basis ，insufficient supervision power ，difficulty in obtaining evidence ， untimely supervision and inadequate department cooperation supervision mechanism. It is necessary to improve the regional cooperative supervision mechanism continuously in perspectives of perfecting legislation ，establishing professional inspector system，improving departmental linkage mechanism ，and strenghtening the database construction.
