摘要
本文通过将Metafrontier分析方法与EBM模型高度融合,构建基于Metafrontier—EBM模型的效率评价新框架,并以医药制造业为例,分析了高技术产业效率的演进规律、变化趋势与潜在成因。研究发现:EBM模型兼容了径向比例和非径向松弛,估算值介于CCR模型和SBM模型之间,能更真实地反映效率水平;资本存量对综合技术无效率的贡献率居首位,且贡献度逐渐提升,研发资本存量和劳动力分别居第二和第三;劳动力和研发资本存量的节约潜力逐渐缩小,固定资本存量的节约潜力先缩小、后扩大,部分省份的投入之间显现替代效应;区域不平衡特征显著,东部效率显著高于中西部,且东部与中西部之间存在技术落差,但落差逐渐缩小。
