摘要(Abstract)：

以2016—2020年中国9家钨类上市公司为研究对象，运用数据包络分析法（DEA）和Malmquist指数模型分别进行静态分析和动态分析，揭示我国钨类上市公司的运行效率及发展状况。从研究结果可知，我国钨类上市公司的整体效率较高，纯技术效率和规模效率都保持在较高的水平，但是规模效率要低于纯技术效率。全要素生产率在企业效率中呈现先降后升的趋势，表示我国钨类上市公司效率仍处于不稳定的状态，存在一定的风险。研究表明全要素生产率受技术进步的影响较大，进一步说明我国钨类企业在技术革新方面还有待加强。为此提出几点建议：一是增加研发投入在企业经营成本中的占比；二是提高企业管理效率；三是合理控制企业规模。
