摘　　要：选取1991—2022年发布的126项稀土产业政策,通过文本挖掘与社会网络方法选定9项一级指标和49项二级指标,构建PMC指数模型,结合PMC指数与曲面对我国稀土产业政策文本进行分析与评价。研究表明:我国稀土产业政策呈现统领性文件效力强,不同阶段政策重点差异性大;政策整体呈现随行政级别的降低,实用性与操作性愈强的特点;政策总体设计较为合理,但在调控范围、激励措施、长期规划等方面具有改善空间。126 policies on rare earth industry released from 1991 to 2022 were selected,9 first-level indicators and 49 second-level indicators were selected through text mining and social network methods,PMC index models were constructed,and China's policy texts on rare earth industry were analyzed and evaluated by combining PMC indices and surfaces.The results show that China's policy on rare earth industry presents a strong overarching document,and the policy priorities at different stages are very different.The overall policy shows the characteristics of being more practical and operational as the administrative level decreases.The overall design of the policy is reasonable,but there is room for improvement in the scope of regulation,incentive measures,and long-term planning.
