本文采用未知断点的Quandt-Andrews方法检验了全要素生产率增长的结构变化,基于R&D驱动TFP增长的门限面板回归模型进行实证分析,结论认为:全国高技术产业研发对全要素生产率增长呈现倒“U”型影响;东部地区研发存量差距的扩大,使得研发对全要素生产率增长的驱动效应明显减弱;中部地区高技术产业化水平不高导致其出现了“R&D生产率悖论现象”;由于研发资源的利用效率较低等原因,西部地区高技术产业中R&D驱动TFP有效增长的门槛最高。
In this paper, the Quandt-Andrews method with unknown breakpoints is used to test the structural changes of TFP growth and the empirical analysis based on the threshold panel regression model of R & D-driven TFP growth. The conclusion is that: the national high-tech industry research and development to the total factor productivity growth, The driving effect of R & D on the growth of total factor productivity is obviously weakened; the low level of high-tech industrialization in the central region leads to the phenomenon of “paradox of productivity R & D” ; Due to the low utilization efficiency of R & D resources and other reasons, the threshold of effective R & D-driven TFP growth in western high-tech industries is the highest.
