中文摘要：

经营效率作为衡量上市公司治理状况是否良好的重要指标，是具有一定研究价值的。文章基于CCR模型对我国15家开采业上市公司在2010年度的经营效率和规模收益进行了研究，通过选定反映公司规模实力及抗风险能力大小的3个投入指标和反映公司整体获利能力及经营状况的2个产出指标，并结合15家开采业上市公司的年报数据进行运算分析。分析结果表明，我国开采业上市公司在2010年度经营效率总体水平不高，发展势态较弱，存在进一步提升的空间。最后通过数据结果从微观和宏观层面上对开采业上市公司未来的发展提出了建议。

英文摘要：

As an important index that evaluates the business condition of the public company, business efficiency deserves a deep research. This article is focused on the research about business efficiency and scale returns of 15 listed companies in mining industry in 2010 based on CCR model. Through selecting three input indexes that re- flect the scale and ability of a company that resists the risk, and two output indexes that reflect the total profit abil- ity and business condition, this article calculates and analyzes the data from the annual report of 15 listed compa- nies. The result shows that the total business level of public companies in mining industry is low, and the develop- ment trend is weak, and thus there is enough room to progress. Finally, this article adjusts the input-output index in theory with the projecting analysis method, and offers suggestions about the development of public companies in mining industry in microcosmic and macroscopic view according to the data processed.
