湖南省高端装备制造业技术创新效率评价研究——基于DEA和Malmquist指数模型

Research on Evaluation of Technological Innovation Efficiency of High-End Equipment Manufacturing Industry in Hunan Province:An Index Model Based on DEA and Malmquist

为研究湖南省高端装备制造业的技术创新效率,对2011—2016年湖南省高端装备制造业5个细分产业的技术创新效率进行了静态和动态研究。静态研究结果表明:湖南省高端装备制造业大部分产业为DEA有效,其中部分产业没有达到DEA有效,主要是由规模效率偏低造成的。动态研究结果表明:2011—2016年湖南省高端装备制造业的全要素生产率大于1,但增长速率较为缓慢,其主要影响因素是技术进步指数较低。故可知技术进步对全要素生产率起主要的限制作用,且湖南省的技术水平有待加强。最后,在实证分析的基础上,建议从提高资源利用率,发挥集群优势;促进湖南省科研院所、高等院校和高端装备制造业的大力合作;引进发达国家装备制造业的关键技术,努力吸收并创新等3个方面着手提高湖南省装备制造业的技术创新效率。

In order to study the technological innovation efficiency of high-end equipment manufacturing industry in Hunan Province,a static and dynamic research has thus been carried out on the technological innovation efficiency of five subdivision sectors of high-end equipment manufacturing industry in Hunan Province from 2011 to 2016.The static research results show that most of the high-end equipment manufacturing enterprises in Hunan Province are DEA effective,and still some of them are not DEA effective due to their low scale efficiency.The dynamic results show that the total factor productivity of high-end equipment manufacturing industry in Hunan Province is greater than 1 from 2011 to 2016,but the growth rate is relatively slow,with the low technological progress index being the main influencing factor.Therefore,it can be inferred that technological progress plays a major role in the limitation of TFP,an indication that the technical level of Hunan Province needs to be strengthened.Finally,based on the empirical analysis,it is suggested to improve the technological innovation efficiency of equipment manufacturing industry in Hunan Province from three aspects:improvement of the utilization rate of resources with full play given to the advantages of cluster;promotion of the cooperation between scientific research institutes,universities and high-end equipment manufacturing industry in Hunan Province;introduction,assimilation and innovation of key technologies of equipment manufacturing industry of developed countries.
