本文利用DEA方法测算了中国的原始创新、集成创新和消化吸收再创新能力,并在此基础上考查了三种创新能力在中国技术进步中的作用。分析结果表明,原始创新和集成创新能力均抑制了中国的广义技术进步,只有消化吸收再创新能力对中国广义技术进步有正向作用,但作用不显著。剔除技术效率后,对狭义技术进步的研究得到了与上述分析基本一致的结论。通过状态空间模型的进一步分析,我们发现原始创新能力和集成创新能力对中国技术进步的贡献度在1998年之后呈持续上升趋势,而消化吸收再创新能力的贡献度则在1998年之后显著下降,直至2002年左右各种创新能力的贡献度渐趋平稳。本文的研究还发现,中国的人力资本水平还未达到促进技术进步的临界值。
In this paper, we use DEA to measure China’s original innovation, integrated innovation and digestion, absorption and re-innovation capabilities, and based on that, we examine the role of the three innovation capabilities in China’s technological progress. The analysis shows that the original innovation and integrated innovation all inhibit China’s broad-based technological progress. Only the digestion and absorption and re-innovation have a positive effect on China’s broad-based technological progress, but the effect is not significant. After excluding the technical efficiency, the research on narrow technological progress has been basically consistent with the above analysis. Through the further analysis of the state space model, we find that the contribution of original innovation capability and integrated innovation capability to China’s technological progress has been on an upward trend since 1998, while the contribution of digestion and absorption and re-innovation capability dropped significantly after 1998, Until 2002, the contributions of various innovative capabilities gradually stabilized. The research in this paper also finds that the level of human capital in China has not reached the critical value of promoting technological progress.
