高技术产业不同资本类型企业创新效率分析——基于三阶段DEA模型

Analysis on Innovation Efficiency of the Different Capital Type Enterprises in High-tech Industries——Based on the Three-stage DEA model

三资企业和国有企业的效率差别直接影响社会经济的协调发展.高技术产业多为改革开放以后发展起来的新兴产业,不同资本类型企业的效率如何,值得深入探讨.文章运用三阶段DEA模型对我国高技术产业中三资企业和国有企业的创新效率进行测量,并剔除了政府资助、行业人员素质、行业研发氛围、行业硬件基础和平均企业规模等环境变量的影响.结果显示,三资企业和国有企业的纯技术效率基本无差异,导致二者创新效率差距的主要是规模效率,且国有企业的规模效率持续保持低水平.

The efficiency difference between foreign-invested and state-owned enterprises has a direct impact on the co- ordinated development of social economy. Most of the high-tech industries are new-emerging industries developed after the reform and opening-up. The efficiency of different capital type enterprises is worth discussing. It uses the threestage DEA model to measure the innovation efficiency of foreign-invested and state-owned enterprises in China＇s high- tech industries, and excludes the impact of the environment variables, such as government funding, qualification of technical personnel, R＆D atmosphere, average enterprise scale, and hardware base in the industries, and so on. The results show that foreign-invested and state-owned enterprises almost have no differences on their pure technical efficien- cy. Their difference in innovation efficiency mainly comes from scale efficiency, and the scale efficiency of the state- owned enterprises is continuously at a low level.
