摘要
结合煤炭行业特点,先运用数据包络分析方法对2017年煤炭产出量前8的省份的煤炭供应链效率进行静态分析,然后运用Malmquist指数对这8个省份2010—2017年的煤炭供应链效率进行动态分析。结果表明:我国煤炭行业供应链整体水平较低,煤炭行业全要素处于不稳定状态,但总体呈上升趋势,煤炭产能及绿色供应链发展仍有可提升的空间,煤炭行业相关设施的利用程度仍可提高。
Combined with the characteristics of the coal industry,the data envelopment analysis method is used to statically analyze the coal supply chain efficiency of the top eight provinces in terms of coal output in 2017,and then the Malmquist index was used to dynamically analyze the coal supply chain efficiency of the eight provinces from 2010 to 2017.The overall analysis results showed that the overall level of China’s coal industry supply chain was low,the overall factor of the coal industry is in an unstable state,but the overall upward trend,there is still room for improvement in coal production capacity and green supply chain development,and the utilization of related facilities in the coal industry can be improved.
