摘要
世界矿业环境的变化导致我国钢铁企业的原材料成本剧烈上升,这对我国钢铁企业的规模经济效率提出了更高的要求。同时,国内煤炭价格、电力价格的波动以及中国投资拉动型经济的逐步转型,使得对钢铁需要的增速势必放缓,改变钢铁企业的粗放式经营、提高企业的规模经济效率已成为我国钢铁企业的重要任务。通过DEA方法进行实证检验得出,大型和特大型钢铁企业相对于部分规模较小的企业而言不具备显著的效率优势,各家钢铁企业纯技术效率的差距要大于规模技术效率的差距。进一步分析得出,规模经济目前无法成为我国钢铁行业重组的理由,钢铁行业在重组之后的融合问题亟待解决。
The world mining industry competition has been intensified day by day. On the one hand the unceasing rise of coal price, the short supply of electric power, and the market fiercely raised the raw material cost of iron and steel enterprises. Therefore, there is a higher request to China＇ s iron and steel enterprise＇ s economies of scale efficiency. This thesis aims at analyzing the scale efficiency of iron and steel enterprises and the influencing factors. The authors learned from this thesis that there is no significant advance between big and small enterprises. The difference on technique efficiency is much bigger than that on scale efficiency.
