Green energy as a new determinant of green growth in China: The role of green technological innovation

As China attaches great importance to accelerating the energy transition, improving national innovation capability, and achieving green growth, it is essential to investigate the nexus of green energy, technological innovation, and growth (3G). This paper utilizes the system generalized method of moments (SYS-GMM) estimator for exploring the impacts of green energy and green technological innovation on green growth. This paper also investigates the moderating and mediating roles of green technological innovation, heterogeneity, and asymmetry in 3G nexus. Therefore, the following conclusions are highlighted: (1) Green energy and green technological innovation are positively associated with green growth, and green technological innovation can enhance the positive influence of the green energy on growth and further promote sustainable economic development; (2) green technological innovation is a positive mediator in the impact of green energy on growth; (3) the impact of green energy is heterogeneous and asymmetric, while the influence of green technological innovation is consistent. This study highlights several policy implications aimed at enhancing green growth and sustainable development in China.
