中小型高技术企业R&D效率的评价与分析——基于三阶段DEA模型

Evaluation and Analysis of R&D Efficiency in Small and Medium-sized High-tech Enterprises——Based on the Three-stage DEA Model

运用2005—2014年高技术企业的面板数据,基于三阶段DEA模型对中国中小型企业的投入产出效率进行评价,并与大型企业进行了对比分析。在此基础上,运用DEA-Malmquist生产率指数对中国不同规模类型高技术企业R&D的全要素生产率及其分解指数的变化趋势进行了分析。结果表明:样本期间高技术企业总体的全要素生产率有一定幅度的提升,且主要得益于技术进步,但小型企业的全要素生产率增长幅度远远小于大中型企业。最后,根据实证结果得出了相关的结论和政策建议。

Based on the three stage DEA model, we use high tech enterprises panel data from 2005 to 2014 to evaluate the R＆D input and output efficiency of Chinas small and medium sized high tech enterprises firstly, and compare it with large enterprises. Then we use the DEA Malmquist productivity index to analyze the change trend of total factor productivity and decomposition index of R＆D of high tech enterprises of different scale types in China. The estimation results show that the total factor productivity of the whole high tech industry has a certain increase in the sample period, and it mainly benefits from the improved skill, but small scale enterprises Malmquist total factor productivity growth rate is far less than large and medium sized enterprises. At last, the relative conclusion and policy suggestion are given according to the empirical results.
