我国通信设备制造业创新效率的再测度——基于链式关联网络DEA

Analyzing the Innovation Efficiency Evaluation of Chinese Communication Equipment Manufacturing Enterprises with Chain-typed Relational Network DEA Approach

摘要:

以中国通信设备制造业为研究对象,将创新过程分解为两个相互关联的创新链式子阶段(管理阶段和获利阶段),通过构建链式关联网络DEA模型对技术创新的整体及各子阶段的效率进行评价。研究发现,目前中国通信设备制造业无论是研发生产的管理阶段和研发成果商业化的获利阶段的子效率,还是创新过程的综合效率,效率值都普遍较低。不同规模企业的创新效率差异显著,规模以上企业的管理效率较低,而获利效率则较高；中小企业往往具有较高的管理效率而获利效率较低。不同企业应对创新各个子阶段进行监控,并采取差异化的提升策略。

Abstract:

Taking the Communication Equipment Manufacturing Industry of China as research target, this paper decomposes the innovation process into two sub-processes (management stage and profit-making stage) and evaluates the efficiencies of the whole and each stage by constructing the chain-typed relational network DEA model. The empirical results show that the efficiency scores of communication equipment manufacturing industry of China are not high, not only in the sub stage of R D management process and profit-making process, but also in the overall process of innovation. The difference of innovation efficiency among enterprises of different sizes is significantly, enterprises above designated size always with lower management efficiency and higher profit-making efficiency, SMEs always with higher management efficiency and lower profit-making efficiency in contrast. Different types of innovative enterprises should monitor each innovation sub-process and adopt diverse strategy.
