讨论了已有的资源利用效率研究成果，分析了矿产开发利用效率的内涵，在此基础上定义了矿产开发利用效率及其计算公式。为了消除价格因素影响，进一步提出了基于时间要素的效率增量概念及其计算公式。两项指标能较好地反映矿山企业状况，可以比较不同企业之间技术水平。最后，给出了不同矿山企业的矿产开发利用效率和差分效率的汇总计算办法以及计算实例。

The paper reviewed former research results , discussed MPE's connotation ,thus put for-ward a new MPE definition and a new MPE calculating formula .Furthermore,a concept of Differ-ence MPE based on time function was put forward for comparing MPE's of different mines ,and its calculation formula followed .MPE and Difference MPE could reflect products improvement of a mine,which makes it possible to compare technological progress among different mines .Finally,the paper introduced a summation equation of different mines'MPE and different MPE .Some calcula-tion examples were also included .
