摘要(Abstract):

海工装备制造业作为海洋战略性新兴产业,是当前我国拓展蓝色经济空间、推动产业升级的重要领域。基于DEA的三阶段评价模型,首先对18家海工装备制造业上市公司的效率进行初始阶段评价;对于处于生产前沿面上的多家企业,通过引入Jackknifing方法,对生产前沿面进行稳健性检验并剔除了异常指标,在此基础上,加入最优虚拟决策单元,对剔除异常值后的公司进行第二阶段的效率评价;为了更加精细地分析前沿面上的公司如何改善管理,进而实现帕累托最优,又进行了第三阶段评价;最后基于评价结果给出了相应的政策建议。
Marine equipment manufacturing industry, as a strategic emerging industry, is an important area for expanding the blue economic space and promoting the industrial upgrading in China. Based on the three-stage evaluation model of DEA, this paper evaluated the efficiency of 18 listed companies in the marine equipment manufacturing industry first of all; for many enterprises in the frontier, this paper introduced the Jackknifing method to test the robustness of the production frontier and eliminate the abnormal indicators, and on this basis, we added the optimal virtual decision-making unit to evaluate the two-stage efficiency of the companies after eliminating the abnormal value; in order to analyze more subtly how the frontier companies has improved management and then achieved Pareto optimality, this article carried out the third stage evaluation.
