重庆市制造业R&D效率研究——基于三阶段DEA模型

Research on R&D Efficiency of Chongqing Manufacturing——Based on the Three-Stage DEA Model

借助三阶段DEA模型对重庆市制造业R&D效率进行研究,在控制人力资本等环境因素的基础上对重庆市R&D效率进行测度和分析。研究发现人力资本增加有利于提高新产品开发经费存量的利用效率,但会导致R&D人力投入与R&D经费利用效率下降。剔除环境与随机因素后,R&D效率整体呈现下降趋势,纯技术效率过低是综合技术效率低下的主要原因。调整后的R&D效率值表现出较大行业差异,更能反映真实的R&D效率。各行业应充分考虑环境因素以及自身R&D特征以提升相应效率水平。

Applying three-stage DEA model to research on R＆D efficiency of manufacturing in Chongqing and the efficiency was measured based on the control of human capital and other environmental factors. It is found that increase of human capital is beneficial to utilization efficiency of product development funds, but it will lead to the decrease of utilization efficiency in R＆D human resources and R＆D funds. After elimination of environmental and random factors, the efficiency of R＆D generally decline, for which the low efficiency of pure technology is the main reason. The adjusted R＆D efficiency shows a great difference of the industry which shows the real R＆D efficiency. Industries should take into full account of environmental factors and features to improve the R＆D efficiency.
