摘要
以高技术产业为例,建立了创新速度作用机制的理论框架,然后基于面板向量自回归模型和面板门槛回归模型,研究了创新速度的要素替代效应和门槛效应特征。结果表明:创新速度间接作用机制主要体现在,其加快了高技术产业创新对要素的替代效应,高技术产业的技术进步是节约劳动力的技术进步。创新速度的直接效应主要体现在其能给高技术产业带来效益,效益越高的高技术企业,其创新速度的弹性越高。在不同创新速度下,高技术产业资本和劳动力的弹性具有门槛效应:创新速度越高,资本的弹性系数越大,劳动力的弹性系数也越大,但是提高的程度要小于资本。我国高技术产业正处于转型期,资本和创新速度的弹性偏低,质量有待提高。向量自回归模型提供了一种新的计算技术进步偏向的思路。
