摘要
从产业角度研究中国高技术产业技术积累的作用机制,并且评估其绩效,发现潜在问题具有重要意义.文章在理论分析的基础上建立研究框架,综合采用面板数据模型、面板门槛回归模型、贝叶斯向量自回归模型进行研究.结果表明:技术积累对创新的正向机制大于负向机制,技术积累绩效总体良好;中国高技术产业已经进入了技术积累的成熟期,对创新贡献的弹性逐渐降低;随着创新水平的提高,技术积累对创新成果贡献的弹性越大;随着研发经费的提高,技术积累对创新成果贡献的弹性越低:技术积累与研发经费、创新成果之间的互动效应良好.最后提出,应注重革命性新技术积累,鼓励创新能力强的企业进行技术积累的政策建议.
It is of great significance to study the mechanism of technology accumulation in China’s high-tech industry from the industrial perspective,and to evaluate its performance and identify potential problems.This paper establishes a research framework on the basis of theoretical analysis,and comprehensively adopts Panel data model,Panel threshold regression model and Bayesian vector autoregressive model to conduct research.The results show:The positive mechanism of technology accumulation for innovation is greater than the negative mechanism,and the performance of technology accumulation is generally good;China’s high-tech industry has entered the mature period of technology accumulation,and the elasticity of its contribution to innovation has gradually decreased;As the level of innovation increases,the elasticity of the contribution of technology accumulation to innovation achievements is greater;With the increase of R&D expenditure,the elasticity of the contribution of technology accumulation to innovation achievements is lower;The interaction effect between technology accumulation,R&D expenditure and innovation results is good.Finally,it is proposed that we should pay attention to the accumulation of revolutionary new technologies and encourage enterprises with strong innovation capabilities to carry out technology accumulation.
