摘要
选取装备制造业7个行业作为样本,本文运用2002-2010年共9年的相关数据,采用生产前沿面理论中的SFA参数方法研究了中国装备制造业的创新效率。结果表明:企业规模与创新效率之间并不存在着倒U型关系而仅表现为线性关系;市场结构对创新效率的影响呈现先增加后递减的倒U型关系。同时,企业规模和市场结构的交互作用对创新效率均有显著的正向影响,较大的企业规模和充分竞争的市场结构相结合更有利于创新效率的提高。另外,引进技术的消化吸收能力正向作用于创新效率,而且影响作用十分显著。
This study selected seven industries as a sample of the equipment manufacturing industry u- sing of 2002 -2010 year of data, using the SFA parameters method. The results showed that： the inverted U shaped relationship does not exist and just show a linear relationship between the output value and the number of employees to measure firm size and innovation efficiency. The impact of market structure on innovation efficiency firstly increase and then decrease, showing the inverted U - shaped relationship. Through the estab- lishment of the interaction between firm size and market structure, the interaction between the two has significant positive impact on innovation efficiency, that means large scale enterprises and fully competitive market structure combining more conducive to the improvement of the efficiency of innovation. The introduction of technology digestion and absorption are also forward the role of innovation and efficiency, and its effects are more pronounced.
