基于DEA-Malmquist指数的煤炭企业新旧动能转换绩效评价

Performance evaluation for new and old kinetic energy conversion of coal enterprises based on DEA-Malmquist index

随着煤炭企业新旧动能转换工作的逐步开展,其绩效评价问题迫切需要解决。基于此,文章采用非参数的DEA-Malmquist指数方法对煤炭企业2015—2018年新旧动能转换绩效进行了定量分析。结果表明,我国煤炭企业平均技术效率为0.731,存在资源浪费现象。技术进步拉动了全要素生产率的增长,短时间内企业新旧动能转换绩效显著,但存在下滑的趋势。煤炭企业只有保持技术创新,提高管理水平,持续优化资源配置,才能提高新旧动能转换绩效水平。

With the gradual conversion of new and old kinetic energy in coal enterprises,the problem of performance evaluation needs to be solved urgently.The nonparametric DEA Malmquist index method is used to quantitatively analyze the performance of coal enterprises in 2015—2018.The results show that the average technical efficiency of coal enterprises in china is 0.731,indicating the wasting of resources.Technological progress has promoted the growth of TFP.In a short period of time,the transformation performance of new and old kinetic energy of enterprises is significant,but there is a downward trend.Only by maintaining technological innovation,improving management level and continuously optimizing resource allocation can coal enterprises improve the performance level of new and old kinetic energy conversion.
