Rare earth elements are important resources for national development and industrial upgrading,and it is critical to establish an improved rare earth policy system.Based on the constructed analysis framework of rare earth policies,48 rare earth policies issued from 1985 to 2022 in China were evaluated by using text data mining,social network and policy modeling consistency(PMC)-index model from three aspects,including the evolution process of rare earth policies,policy network and quantitative policy analysis.It is found that the evolution of China's rare earth policies can be divided into four stages,among which standardizing the exploitation procedure for rare earth resources and rectifying the order of rare earth market have always been the focus of China's rare earth policies.A policy network has been initially constructed,but there is poor correlation among policies and there are many isolated policies,which indicates that the correlation among policies needs to be strengthened.The overall design of the polices is reasonable,but there are some deficiencies in incentive measures and effectiveness.Finally,some suggestions are put forward to optimize and improve China's rare earth policies based on the features and shortcomings.
