Abstract

Abstract: Energy technology innovation plays a crucial role in the reduction of CO₂ emissions and environmental preservation. In order to explore whether there is causal relationship between energy technology patents and CO₂ emissions, this paper considers GDP as a control variable and builds dynamic panel data model using difference GMM(DIF-GMM) based on the data for 30 provinces in mainland China from 1996 to 2008. The results indicate that there are long-term equilibrium relationships among energy technology patents, CO₂ emissions and GDP; in short-term, the role of energy technology patents in reducing CO₂ emissions is limited in the national, and there are greater differences in different regions, energy technology patents have no significant effect on CO₂ emissions reduction in eastern and central of China except for in western China.

Key words: CO₂ emissions, energy technology patents, dynamic panel data approach, panel-based VECM
