创新持续、创新质量对碳排放的影响效应研究--基于2006-2017年的省际面板数据

Research on the Influence Effect of Innovation Persistence and Innovation Quality on Carbon Emissions

分析了创新持续、创新质量对碳排放影响效应机制,并利用2006—2017年我国省际面板数据,运用面板模型与面板门槛模型估计方法,实证检验创新持续与创新质量对碳排放的影响,研究结果表明:创新持续与碳排放的关系为倒“U”型曲线,创新质量对碳排放的影响存在贸易开放水平与制度水平单门槛效应,即随着贸易开放水平与制度水平的提升,创新质量对碳排放的抑制作用增强,且创新质量与创新持续协同项对碳排放的抑制作用将会增强。

This paper analyzes the impact mechanism of innovation sustainability and innovation quality on carbon emissions.By using provincial panel datas from 2006 to 2017,using panel model and panel threshold model estimation method,this paper empirically tests the impact of innovation sustainability and innovation quality on carbon emissions.The results show that:the relationship between innovation sustainability and carbon emissions is an inverted“U”shaped curve,the impact of innovation quality on carbon emissions has single threshold effect of trade openness level and institutionalization level.That is,with the increase of trade openness and institutionalization level,the elasticity of innovation quality to carbon emission suppression increases,and the synergistic effect of innovation quality and innovation sustainability on carbon emissions will be enhanced.
