基于数据包络分析的煤矿安全管理效率评价

Efficiency evaluation of coal mine safety management based on data envelopment analysis

安全管理效率作为评判煤矿管理工作的重要方面。针对不同煤矿,本文提出了提升的安全管理效率的具体建议。以安徽省为例,共选取了17个企业样本,通过统计年鉴、企业年报等方法搜集满足计算需求的样本数据,构建了‘从业人数、培训次数’两个输入指标和‘事故次数、伤亡人数、年产量’三个输出指标,借助数据包络分析模型对2015~2019年间各样本的安全管理效率进行评价,静态分析结果表明:样本企业的综合技术效率、纯技术效率、规模效率均处于中等水平,仍有很大的进步空间。运用动态指数模型,补充样本企业安全管理的动态变化指标。动态结果表明:样本企业在2015~2019年间总体处于进步状态,但进步率在减少。

Safety management efficiency is an important aspect of evaluation coal mine management.For different coal mines,this paper proposes specific suggestions to improve the efficiency of targeted safety management.Taking Anhui Province as an example,a total of 17 enterprise samples are selected to collect the sample data to meet the calculation needs through the relevant statistical yearbook,enterprise annual reports and other methods.Two input indicators of"number of employees,number of training"and three output indicators of"number of accidents,casualties and annual output"are constructed.The data envelopment analysis is used model to evaluate the safety management efficiency of each sample from 2015 to 2019.The results of static analysis show that the comprehensive technical efficiency,pure technical efficiency and scale efficiency of the sample enterprises are in the middle level,and there is still much space for improvement.And the dynamic index model is used to supplement the dynamic change index of sample enterprise safety management.The dynamic results show that the sample enterprises in 2015-2019 are in a state of progress form,but the rate of progress is mostly in the state of decreasing.
