摘要
基于DEA-Malmquist模型,对皖江城市带装备制造业2009-2014年效率进行分析得出以下结论:第一,在时间维度上,综合效率的变化趋势与技术变动指数差别较大而与純技术效率和规模效率变化趋势较为一致,特别是与规模效率几乎重合;第二,通过纵向比较发现,综合效率的空间分异程度在不断缩小,但内部空间格局变化较大;第三,技术变化在全要素生产率指数提升方面起到了关键作用;第四,皖江城市带技术效率得到很大改进,要素的投入和产出配置越来越合理有效。
Based on DEA- Malmquist model of Wanjiang city belt,we analyzed the efficiency of the equipment manufacturing industry in 2009- 2014 and it is concluded that ： 1From the aspect of the time dimension,the change trend of comprehensive efficiency and technology changes index difference is bigger,and pure technical efficiency and scale efficiency change trend is relatively consistent,particularly with scale efficiency is almost perfect. 2Through the longitudinal comparison of the efficiency,the comprehensive efficiency of spatial differentiation degree is narrowing,but the internal spatial pattern changes. 3Technology changes in total factor productivity index has played a key role. 4Wanjiang city belt technical efficiency has been greatly improved,the elements of the input and output configuration are more and more reasonable and effective.
