China has set up the dynamic adjustment mechanism of National Reimbursement Drug List (NRDL) since 2019. The establishment of this dynamic adjustment mechanism was caused by “The Drug God Event”, which is the policy window of the NRDL adjustment. The adjustment responded to the public’s questions in the problem stream, showed the political stream of government concern about public services and health care, absorbed experts’ advice on the medical insurance drug issue in the policy stream and realized the annual update of NRDL. The government and other subjects should build a more convenient input channel for public suggestions, increase input strength, and establish a more friendly political system to reply to society’s needs in time, construct policy agenda and promote the progress of the country.
