河北省钢铁产业技术效率评价及对策研究

以2001年—2009年面板数据为基础,运用数据包络分析（DEA）方法,对河北省等六省区钢铁产业整体效率、技术效率、规模效率、投入冗余及超效率进行评价,并运用Malmquist效率指数对河北省钢铁产业的全要素生产率变动进行动态分析。研究结果表明,河北省钢铁产业整体效率在不断提高,其中,纯技术效率的贡献要大于规模效率;在产出不变的情况下,河北省钢铁产业存在着一定程度的投入冗余;产业超效率值总体上表现出不断提升的态势;技术进步对本省钢铁产业技术效率的影响并不稳定,呈波动变化状态。河北省要想提高钢铁产业总体效率,必须加快技术进步、优化产品结构、提高产业集中度和有效减少投入冗余。

The Technical Efficiency Evaluation and Countermeasure Study for Iron and Steel Industry in Hebei

Based on the panel data from 2001 to 2009,this study uses Data Envelopment Analysis(DEA) to calculate the technical efficiency,pure technical efficiency,scale efficiency,input redundancy and super efficiency of iron and steel industry for six districts including Hebei.Meanwhile,it uses Malmquist index to make a dynamic analysis on the variation of total factor productivity.The results show that the technical efficiency of iron and steel industry in Hebei is increasing gradually.In comparison,and the contribution of the pure technical efficiency is larger than the scale efficiency.Under the condition of invariable output,we find the input congestion is another problem.In general,the super efficiency is steadily increasing.However,the effect of technical progress is unstable and fluctuant.The iron and steel industry in Hebei should quicken the technical progress,optimize industrial structure,enhance industry concentration and reduce the input redundant in order to improve the overall efficiency.
