创新政策对全要素生产率的影响及其溢出效应

A study on the effect of innovation policy on TFP and its spillover effect

本文旨在揭示创新政策对区域经济发展的影响。通过对中国30个省级行政区域2001-2017年创新政策对全要素生产率的影响及其空间溢出效应的研究发现,区域创新政策显著地影响全要素生产率水平,并且这种影响主要通过劳动扭曲而形成。从政策工具异质性的角度来看,政府资金对全要素生产率的提升作用最大。从空间溢出效应角度的分析表明,创新政策对全要素生产率的影响具有显著的空间溢出效应,一个地区的创新政策不仅会直接影响本地区的全要素生产率,而且这种影响会辐射到相邻地区,产生正向溢出效应。本文的研究结论肯定了区域创新政策对于区域经济发展的激励引导作用以及对其他地区所产生的标杆和示范作用。

This paper aims to reveal the effect of innovation policy on regional economic development.Through the effect of innovation policy on TFP and its spatial spillover effect in 30 provincial regions of China from 2001-2017,we find innovation policy has a significant impact on TFP,and this effect is mainly driven by labor distortion.The government funds play the most important role comparing with other policy tools.And innovation policy not only has a significant direct effect,but also has a significant spatial spillover effect.In other words,the innovation policy will not only directly affect the TFP of the region,but also affect the TFP of neighboring regions.This paper affirms the role of the innovation policy in stimulating and guiding the regional economic development,and its demonstration role for other regions.
