我国高技术产业自主创新能力评价——基于DEA的Malmquist生产率指数分析

本文采用DEA方法,计算了1995—2007年13年间我国高技术产业17个行业全要素生产率的Malmquist指数,并对全要素生产率进行分解研究,结合R&D强度这一指标综合反映高技术产业的自主创新能力。最后得出主要结论:我国高技术产业技术进步率低,自主创新能力较弱,与发达国家相比存在很大差距,但这一现状在逐年改善。

Appraise on High-Tech Industries Innovation Ability in China: An Analysis of Malmquist Index

This paper adopts DEA method to calculate Chinese 17 high-tech industries＇ malmquist index of total factor productivity during the 13 years from 1995 to 2007,and it also studies on decomposition of total factor productivity.Meanwhile the combination with R D intensity of the indicators is also used to comprehensively reflect the independent innovation ability of high-tech industry.The main conclusions from the analysis described above are：Chinese technological progress rate of high-tech industry is low and the independent innovation ability is weak.Fortunately,although there is a huge gap about independent innovation ability between the China and other developed countries,this situation has been improved each year.
