Emission Reduction Effect of Renewable Energy Technology Innovation:Spatial Spillover and Threshold Characteristics
Renewable energy technology innovation is an important driving force to achieve green and low-carbon development.Based on the panel data of 30 provinces in China from 2003 to 2020,a fixed-effects model is constructed to analyze the impact of renewable ener-gy technology innovation on carbon emissions and regional heterogeneity,a spatial Durbin model is used to explore the spatial spillover effect,and a threshold regression model is used to test the nonlinear impact of renewable energy technology innovation on carbon emis-sions.The results show that:in terms of the whole country,renewable energy technology innovation significantly suppresses carbon e-missions;by region,the carbon reduction effect of renewable energy technology innovation is significant in the eastern region,but not significant in the central,western and northeastern regions.Spatially,renewable energy technology innovation not only reduces carbon emissions in the region,but also promotes carbon emission reduction in neighboring regions.The higher population and R&D invest-ment,as well as the lower environmental regulation,can strengthen the promoting effect of renewable energy technology innovation on carbon emission reduction.
