| 总结: | Green technology innovation (GTI) helps to promote the transformation
of energy development and achieve low-carbon development. This paper
evaluates the effect of GTI on energy intensity (EI) using a sample of
China's provincial panel data from 2001 to 2019. First, using a mediation
effect model, we study the potential pathways of GTI that affect EI.
Moreover, we examine whether the GTI has a spatial spillover and
threshold effect by using the spatial econometric model and threshold
regression. The results show that there is a positive effect of GTI on
reducing EI, and this effect is partly realized through the industrial
structure transformation and upgrading. In addition, the influence has a
spatial spillover effect between regions. Finally, we find that GTI has
heterogeneous effects on EI due to differences in regional economic
development levels.
