Abstract
Green technology innovation is one of the important ways to
achieve carbon emission reduction targets. Based on the STIRPAT (Stochastic Impacts by Regression on
Population, Affluence and Technology) model and the fixed-effects model, we measured CO2
emissions by region using regional panel data from 2005 to 2021 at provincial
level in China and explored the CO2 emission reduction effect. Based
on this, we analyzed heterogeneity of green technology innovation and the
mechanism of the effect. The results show that green technology innovation has
a significant effect on carbon emission reduction, achieving a 5% reduction.
Second the CO2 emission reduction effect of green technology
innovation varies according to differences in economic, scientific and
technological human resources, and environmental management inputs. It shows
that green technology innovation has a significant CO2 emission
reduction effect in economically developed regions, regions with sufficient
scientific and technological human resources, and regions with high
environmental management inputs. Third, green technology innovation mainly
achieves CO2 emission reduction by improving the level of
cleanliness.
