中国制造业生产效率测度及时空演变特征研究

摘要

基于JLMS思想推导了分离公式 ,并运用面板三阶段DEA模型测算了我国2000-2012年省级制造业生产效率 ;通过构造"GE"矩阵 ,分析了生产效率的时空演变特征.研究表明 :创新环境和对外开放度是提高制造业生产效率的有利因素 ;东、中、西部制造业生产综合技术效率的差距并非由纯技术效率主导 ,而主要源于规模效率 ;制造业生产效率的演变特征呈现较强的地域性聚类.对此 ,提出了提升我国制造业生产效率的政策建议.%In this paper ,the separation formula is deduced based on the idea of JLMS .The manufactur-ing production efficiency at the provincial level in China from 2000 to 2012 is evaluated by using three-stage DEA model .The spatial-temporal evolution features of production efficiency is analyzed by the establishment of "GE" matrix .The results demonstrate that the innovation environment and the de-gree of openness have positive effect on the manufacturing production efficiency .The gap of the com-prehensive technical efficiency (TE) between the eastern ,central and western regions in China is mainly caused by scale efficiency(SE) instead of pure technical efficiency(PTE) .The homogenization phenomenon of the evolution of manufacturing production efficiency is relatively serious .According to the results , some advices for improving the manufacturing production efficiency in China are pro-posed .
