【摘要】：本文利用基于DEA模型的Malmquist指数方法对有色金属矿采选业上市公司2008~2012年的财务面板数据进行测算,分析采选业全行业及各上市公司的经营效率变动情况。研究发现,采选业全行业经营效率呈现逐年下滑的态势,金融危机冲击对采选业的负面影响日趋加深;采选业内经营效率最优企业出现严重效率衰退是全行业经营效率下滑的主导因素;各上市公司经营效率变动参差不齐反映了金融危机对各微观企业主体的负面影响程度存在差异。
[Abstract]:In this paper, the Malmquist index method based on DEA model is used to measure the financial panel data of the listed companies in non-ferrous metal mining and dressing industry from 2008 to 2012, and to analyze the change of operating efficiency of the whole industry and the listed companies. It is found that the operating efficiency of the whole industry is declining year by year, and the negative impact of the financial crisis on the mining and dressing industry is deepening day by day. The serious efficiency recession in the optimal enterprises is the leading factor for the decline of the operation efficiency of the whole industry. The variation of operating efficiency of each listed company reflects the difference of the degree of negative influence of financial crisis on the main body of micro enterprises.
